How Handheld Laser Welding Works

Laser light from the source is transmitted through an optical fiber to the handheld welding head, where it is focused onto the workpiece surface. The laser energy is absorbed and converted to heat, melting the material or filler wire. Shielding gas protects the molten pool, forming a high-quality weld that securely joins the two pieces.

The water chiller cools and maintains constant temperature for both the laser source and welding head to protect critical components.

Fiber Laser Cleaner

Wed, 28 Oct 2026 00:00:00 +0000

Product Overview

The fiber laser cleaner is a non-contact, green cleaning equipment. It uses high-frequency laser pulses to impact the surface — the light beam rapidly moves, converting into acoustic waves that return from the lower layer, creating resonance with incident waves that breaks down contaminants. Simultaneously, the differential absorption of laser energy between the substrate and surface contaminants causes instant thermal expansion, generating sufficient acceleration to overcome the adsorption force and detach contaminants.

Simple to operate, highly efficient and safe, it is especially advantageous for objects that cannot be moved.

Core Advantages

Non-contact processing — no substrate damage, no secondary pollution
Eco-friendly and efficient — no consumables, no chemicals, no dust emissions
Safe and reliable — modular controls with shielding and safety interlocks
Simple operation — intuitive touch screen, preset cleaning parameters at one touch
High efficiency — spot diameter up to 200mm for large-area rapid cleaning
Wide power range — 1000W / 1500W / 2000W / 3000W / 6000W available

Technical Specifications

Parameter	Specification
Name	Fiber laser cleaner
Laser Power	1000W / 1500W / 2000W / 3000W / 6000W
Operating Mode	Continuous / Modulation (Pulse)
Laser Wavelength	1080nm
Focus Spot Diameter	0 – 200 mm
Fiber Length	10 m
Cooling System	Water cooling
Power Supply	AC 220V / AC 380V
Overall Weight	~ 300 kg

Working Principle

Laser cleaning operates through two combined effects:

Resonance Shattering Effect — high-frequency laser impacts the surface; the beam converts to acoustic waves returning from below, creating resonance with incident waves that shatter contaminants
Thermal Expansion Detachment Effect — substrate and contaminants differentially absorb laser energy, causing instant thermal expansion of contaminants which generates enough acceleration to overcome adsorption forces and detach

Application Industries

Nuclear power industry
Shipbuilding
Tire molds
Rail transit
Automotive parts
High-end machine tools
Industrial molds
Steel structure rust removal
Ancient building restoration
Precision electronics cleaning

Typical Cleaning Targets

VELTRA PSA Nitrogen Generator

Thu, 05 Nov 2026 00:00:00 +0000

Product Overview

The PSA (Pressure Swing Adsorption) nitrogen generator uses clean compressed air as its feedstock. Carbon molecular sieves adsorb oxygen and carbon dioxide under high pressure and desorb them at low pressure, separating nitrogen on site for immediate use — no cylinder handling, no liquid nitrogen delivery, and no evaporation loss. It is widely used for laser welding shielding, laser cutting assist gas, metal heat treatment, and food preservation.

Key Advantages

Generate gas on site, on demand — Cut out bottled and liquid nitrogen suppliers entirely; produce gas the moment you start the unit
Adjustable purity — Nitrogen purity from 95% to 99.999% in multiple grades to match different welding/cutting processes
Stable, self-regulating purity — Intelligent closed-loop control keeps flow and purity steady for consistent shielding quality
Low running cost — Cost per cubic meter is only 30%–50% of bottled/liquid nitrogen, so units pay for themselves quickly
Safe and convenient — Low pressure, ambient temperature operation; no high-pressure cylinders or cryogenic liquid
Saves labor and floor space — No cylinder swapping, compact footprint that sits right next to your production line

Advantages in Laser Welding Applications

The quality of the shielding gas (nitrogen) directly affects weld formation and cutting edge finish. On-site generation gives laser systems these unique benefits:

1. Stable gas flow, more consistent welds

Immediate on-site production keeps pressure and flow steady, giving uniform shielding at the nozzle and low-oxidation, consistent weld color
Avoids weld defects and spatter caused by pressure swings during cylinder changes

2. Controllable purity for multiple materials

When welding stainless steel, galvanized steel or aluminum, adjust the purity grade to precisely match the shielding requirement of each material
For cutting carbon steel or stainless steel, select the right purity for each plate thickness for cleaner edges

3. Integrated with laser lines, zero downtime

Gas production matches consumption in real time with no gaps, ideal for long continuous welding/cutting runs
One nitrogen system can serve multiple welders via centralized supply for maximum utilization

4. Batch consistency and easy scaling

Fully automated quality monitoring ensures consistent gas quality across production batches
Expand your line without renegotiating suppliers — just add capacity modules

Cost Comparison vs Traditional Supply

Aspect	Bottled Nitrogen	Liquid Nitrogen	On-site Generation (this unit)
Supply mode	Ordering & swapping	Tanker delivery	Produced on site in real time
Logistics & handling	Frequent cylinder swaps	Delivery + evaporation loss	No delivery, no handling
Cost per m³	High	Medium-high	Low (about 30%–50%)
Supply risk	Downtime during swaps	Delivery delays	No interruption
Storage safety	High-pressure cylinder	Cryogenic burn/vapor risk	Low pressure, room temp — safest
Floor space	Cylinder storage area	Storage tank + vaporizer	Minimal, next to the line
Purity control	Fixed grade	Fixed grade	Multiple adjustable grades
Ongoing cost	Rental deposits	Tank leasing	Only specialty filter media

Payback reference: For continuous daily use at moderate consumption, on-site generation typically recovers the equipment investment within 6–12 months through gas cost savings, after which savings continue.

Typical Applications

Shielding gas for laser welding / laser cutting
Nitrogen shielding for stainless steel, galvanized steel and aluminum welding

FAQ

Is on-site generation cheaper than buying liquid nitrogen?

Low consumption with short hours might favor purchasing, but laser welding/cutting usually means steady, long-term use. On-site generation costs only 30%–50% per cubic meter, and eliminates cylinder deposits, deliveries and waiting — winning on both total cost and production efficiency.

What installation conditions are required?

You need 380V three-phase power, a 0.6–1.0 MPa clean compressed air source (or we supply a matching compressor), and a 5–45℃ ventilated area. The unit is skid-mounted and plug-and-play on arrival.

Are purity and flow guaranteed to be stable?

Yes. The PLC closed-loop control with inline oxygen analysis monitors continuously, and auto alarms activate on out-of-range concentration or flow, so the output always meets the process requirement.

Will one unit cover multiple welders?

Yes. Size the generator by total gas demand to centralize supply across several laser welders/cutters, and add matching modules when scaling your line.

What is the warranty?

Main unit: 12 months from shipment
Core components (carbon molecular sieves, etc.): per manufacturer standard
Consumables (filter elements, seals): 3 months

Buying Laser Welders from China: A Complete Import Guide for Overseas Buyers

Tue, 27 Oct 2026 00:00:00 +0000

Buying industrial equipment from China can be intimidating — but with the right approach, it’s straightforward and cost-effective. Based on shipping machines to 12+ countries over 10 years, here’s our complete guide.

Step 1: Vet the Supplier

What to check before sending any money:

Check	Why It Matters	How to Verify
Registered company	Avoid personal traders	Ask for business license photo
CE / ISO 9001	EU/global safety compliance	Ask for certificate PDFs
Factory, not trading company	Better pricing, direct support	Ask for factory photos, video call
Existing customers in your country	Smooth import and after-sales	Ask for references
Clear payment terms	Protect your deposit	30% deposit + 70% before shipment is standard

Red flags to avoid:

“Friend/family” operation with no company registration
Refuses to show factory or provide certificates
Requests 100% payment upfront
No WhatsApp / WeChat for direct communication

Step 2: Sample Testing (Critical!)

Don’t skip this step. Any serious supplier will test-weld your material samples for free.

Send these to the supplier:

2–3 pieces of your actual workpiece material (100×100mm minimum)
Mark the joints you need welded
Include a photo of the finished weld appearance you’re targeting

What you’ll get back:

Photos + video of the test weld
Welding parameter report (power, speed, wire feed settings)
Your sample pieces back if you provide a return address

If the test weld doesn’t meet your requirements, move on — no shame, no cost.

Step 3: Payment Terms

Standard industry terms (China → Overseas):

Stage	Amount	When
Deposit	30%	After sample approval, before production starts
Balance	70%	After machine photos + test video sent, before shipment

Never pay 100% upfront. Never use Western Union or MoneyGram for deposits — use T/T (bank wire) or Alibaba Trade Assurance.

Payment methods:

✅ T/T (Telegraphic Transfer) — bank wire, most common
✅ Alibaba Trade Assurance — buyer protection, recommended for first-time orders
✅ PayPal — small amounts only (<$1,000), 5% fee

Step 4: Shipping

Two main options:

Method	When to Use	Cost Range
Sea Freight (FCL)	2+ machines, budget 2–4 weeks	$100 – $300 USD to most ports
Sea Freight (LCL)	1 machine, budget 4–6 weeks	$50 – $150 USD
Air Freight	Urgent, need in 3–7 days	$300 – $800 USD

What’s included in shipping price:

Factory loading fee
Export customs clearance (China)
Ocean/air freight
Full cargo insurance (always get this)

What’s NOT included (you pay locally):

Import duties and taxes (varies by country)
Customs broker fee
Local delivery to your address

Step 5: Import Duties by Country

Country	Laser Welder HS Code	Approx. Duty Rate	Note
United States	8456.11.00	0% (FTA)	No extra duties
EU (Germany, UK, etc.)	8456.11.00	2.7%	CE certificate required
Australia	8456.11.00	0%	GST applies
Brazil	8456.11.00	14% + ICMS	Complex, use customs broker
Indonesia	8456.11.00	5%	Permit required

Important: HS codes and rates change. Always confirm with a local customs broker before ordering.

Step 6: After-Sales & Warranty

This is where many buyers regret choosing a cheap supplier.

What you should demand BEFORE ordering:

Support Item	What You Get
Online training	Free 2–4 hour video call setup + operation training
Warranty	12 months full machine, 24 months laser source
Spare parts	Initial kit included; re-order at cost for 5+ years

Choose Laser Welder: 1000W vs 1500W vs 2000W vs 3000W

Tue, 27 Oct 2026 00:00:00 +0000

One of the most common questions we get from buyers is: Should I buy the 1500W or 2000W model?

The short answer is: it depends on three things — your material thickness, production volume, and future plans.

Quick Decision Matrix

Your Situation	Recommended Model
Welding 0.5 – 3.0mm sheet metal only	1500W Standard
Welding up to 5.0mm thick steel	2000W High-power
Small workshop, low daily output	1500W
Planning to scale up or add automation later	2000W
Budget is tight but need 220V operation	1500W

Key Differences You Must Know

Welding Thickness Range

Model	Max Weld Thickness
1500W	0.5 – 3.0 mm
2000W	1.0 – 5.0 mm

Critical rule: A 1500W machine on 4mm steel will struggle with penetration. A 2000W machine on 1mm aluminum is overkill — the high power may cause burn-through. Match power to your actual thickness range.

Power Supply Requirement

Model	Power Input
1500W	220V single-phase, 16A — plug into any workshop outlet
2000W	380V three-phase, 16A — requires three-phase power supply

This is a dealbreaker for many overseas buyers. If your workshop only has 220V (common in Southeast Asia, Middle East, and some European countries), the 1500W is your only practical option.

Energy Consumption

Model	Approx. Hourly Power Draw
1500W	~ 5 kWh
2000W	~ 7 kWh

Over a year of 8-hour daily operation, the 2000W adds approximately 5,000 kWh of extra electricity cost. That’s roughly $500 – $1,000 USD depending on your local rate.

Weight & Portability

Model	Handheld Unit Weight
1500W	12 kg
2000W	15 kg

A 3kg difference matters for operators holding the gun all day. For extended welding sessions, the lighter 1500W reduces operator fatigue significantly.

Upgrading Later?

Here’s the hard truth: You cannot upgrade a 1500W to 2000W. The laser source is a sealed unit — there’s no software setting or component swap that unlocks more power.

So if you’re planning to expand into thicker materials or higher-volume production within 1–2 years, buy the 2000W now. Selling and replacing a 1500W 18 months from now will cost you more than the price difference today.

Bottom Line

Choose 1500W if:

You weld 0.5–3mm metal sheets
You only have 220V power
Budget is limited
Portability and operator comfort are priorities

Choose 2000W if:

You need to weld 3–5mm thick steel
You have 380V three-phase power
You plan to scale up production
You need auto wire feeding for cosmetic welds

Still unsure? with your material type, thickness range, and daily production target. We’ll recommend the right model — and we can test-weld your samples for free before you order.

Handheld Laser Welder Daily Maintenance: 7 Habits That Extend Machine Life

Tue, 27 Oct 2026 00:00:00 +0000

A handheld laser welder is a 10,000+ hour machine — if you maintain it. Neglect it, and you’ll see problems by hour 2,000.

Based on 10 years of customer feedback and machine service records, here are the 7 daily/weekly habits that dramatically extend machine life.

Daily (Before Work) — 2 Minutes

1. Check the Protective Lens — Most Critical

The protective lens at the tip of the welding gun is the first line of defense. A dirty or cracked lens lets spatter and dust into the optical system, causing catastrophic laser damage.

Check daily:

Remove the lens cover
Inspect for cracks, smudges, or weld spatter
Wipe gently with isopropyl alcohol (95%+) and a lint-free cloth
Replace immediately if cracked or deeply stained

Replacement schedule: Every 200–300 operating hours, or whenever you notice decreased weld quality.

2. Inspect the Copper Nozzle

The copper nozzle directs the shielding gas. Deformation or blockage = bad welds.

Check daily:

Look for dents or deformation at the tip
Blow out any accumulated spatter with compressed air
Replace if deformed (cost: ~$15 USD, takes 2 minutes)

Weekly — 10 Minutes

3. Verify Coolant Level

For water-cooled machines (all our models):

Turn power OFF first
Check the coolant tank level (should be 80–100% full)
Top up with deionized water + anti-freeze mixture (never use tap water)
Replace coolant completely every 6 months

Running dry = laser source overheat = $$$ repair. Never skip this check.

4. Clean the Wire Feeder Rollers

If you use the automatic wire feeder:

Remove the wire spool
Blow out the roller groove with compressed air
Clean any accumulated dust or wire residue
Lubricate lightly with machine oil (not WD-40)

5. Tighten Cable & Connector Screws

Vibration from daily welding can loosen electrical connections.

Check the power cable connector at the machine
Check the optical fiber connector (be very gentle — optical fibers break easily)
Tighten any loose screws

Monthly — 20 Minutes

6. Calibrate Welding Parameters

Over time, the laser power output can drift slightly. Every month:

Weld a test piece on your standard material
Check weld width and penetration against your baseline
Compare machine-displayed parameters to what you recorded at setup
If drift > 10%, contact us for calibration

7. Check and Clean the Laser Gun Housing

Wipe down the entire gun body with a dry cloth
Clean ventilation slots (compressed air)
Check for oil or coolant leaks around seals
Inspect the trigger button for proper operation

Warning Signs You Should Not Ignore

Symptom	Possible Cause	Action Required
Weld suddenly becomes porous / spattery	Dirty lens or deformed nozzle	Replace lens + nozzle immediately
Machine shows error code E-001	Coolant flow blocked	Clean filter + top up coolant
Laser beam appears dim	Lens contamination or source drift	Clean lens; if no fix, contact us
Machine trips circuit breaker	Faulty power cable or overcurrent	Stop use, contact us
Clicking noise when pulling trigger	Trigger contact worn	Replace trigger (we ship spares worldwide)

Full Calibration & Service Every Year

Once per year, we recommend sending the machine to an authorized service center or having a video call calibration with our engineers. This covers:

Full laser power output verification
Optical system alignment
Wire feeder calibration
Safety check (laser radiation leakage)

Service cost: $150 – $300 USD (includes return shipping within China). Overseas service available on request.

Follow these 7 habits and your handheld laser welder will deliver 10,000+ reliable operating hours. Skip them, and you’ll pay for it — with downtime and expensive repairs.

Handheld Laser Welding vs TIG/MIG: 10 Key Differences for Industrial Metal Joining

Tue, 27 Oct 2026 00:00:00 +0000

If you’ve been using TIG or MIG welding for years, switching to handheld laser welding feels like a big change. We’ve put together the 10 most important differences based on real production data from our customers.

Comparison Table At A Glance

Metric	Handheld Laser	Traditional TIG	MIG (GMAW)
Welding Speed	3× faster	Baseline 1×	1.5×
Post-weld Polishing	Not needed	Required	Heavy polishing
Heat Input	Very low	Medium	High
Workpiece Deformation	Negligible	Noticeable	Significant
Operator Skill Required	Easy (1 week training)	Hard (certified welder)	Medium
Hourly Power Cost	~$0.50	~$1.50	~$2.00
Consumables Cost / 100 welds	~$2	~$8 (argon)	~$5
Weld Quality Consistency	Very high	Variable	Variable
Equipment Cost	$6,000 – $10,000	$500 – $1,500	$300 – $1,000
ROI Timeline	4 – 8 months	N/A	N/A

1. Welding Speed — Laser Is 3× Faster

The 3× speed improvement is real and consistent across materials. On 2mm stainless steel:

Laser welding: 300mm weld in ~10 seconds (30 mm/s)
TIG welding: 300mm weld in ~30 seconds (10 mm/s)

This means one laser welder can replace two to three TIG stations in a production layout.

2. Zero Post-weld Polishing

This is the single biggest labor saver. Laser welds are:

Narrow (≤ 1.2mm)
Clean, no slag
Uniform appearance

TIG and MIG welds both produce visible weld reinforcement that requires grinding and polishing — adding 30–60% extra time per workpiece.

3. Minimal Heat Input = No Deformation

Low heat input means:

No warping on thin sheet metal
No pre-heating required for most applications
Adjacent materials (paint, coatings) are not affected

For precision parts like battery trays or kitchenware, this eliminates an entire correction step after welding.

4. Operator Skill — 1 Week vs 6 Months

Traditional TIG requires certified welders with 6+ months of training. Laser welding is so forgiving that a new operator can produce production-quality welds after 3–5 days of supervised practice, and be fully independent within a week.

Your skilled welders can move to higher-value tasks like setup and quality control.

5. Power Cost — 3× Lower Per Hour

Method	Hourly Power Draw	Approx. Cost at $0.10/kWh
Laser 1500W	5 kWh	$0.50
TIG 400A	15 kWh	$1.50
MIG 400A	20 kWh	$2.00

Over 2,000 operating hours per year, laser saves $2,000 – $3,000 in electricity alone.

6. Consumables — Cheaper, Simpler

Consumable	Laser	TIG	MIG
Shielding Gas	None (wire feeder optional)	Argon (expensive)	Mixed gas
Electrode / Tip	1 copper nozzle ($0.50, 100+ hours)	Tungsten electrode ($2–5 each)	Contact tip ($1 each)
Filler Material	Wire only	Wire + gas	Wire + gas

7. Weld Quality — Machine-Controlled

Laser welds are consistent because the laser power, pulse frequency, and travel speed are all digitally controlled by the machine. With traditional methods, weld quality depends heavily on operator technique and can vary shift to shift.

8. Equipment Cost — Higher Upfront, Lower Total Cost

Laser welders cost $6,000 – $10,000 upfront vs $300 – $1,500 for traditional machines. But the total cost of ownership (including labor, power, consumables, and rework) is 30–50% lower within the first year of use.

Most customers see full ROI in 4–8 months.

9. Portable, No Fume Extraction Required

Handheld laser welders are air-cooled (or water-cooled) and produce minimal smoke. No dedicated fume extraction system is required — unlike TIG/MIG which generate significant welding fumes that must be captured.

10. Works On Materials Traditional Methods Struggle With

Laser welding is particularly effective for:

Dissimilar metals (steel + aluminum)
Thin materials (0.5mm – where TIG/MIG cause burn-through)
Highly reflective metals (copper, brass — requires specific laser parameters)

When NOT to Switch

Laser welding is not perfect for every situation:

Very thick steel (> 6mm) — need multi-pass welding or automated gantry systems
Rough / poorly fitted joints — laser needs tight gap control; use TIG for gap filling
Extremely low-volume one-off work — traditional methods may be more cost-effective

But for high-volume, sheet metal, cosmetic-quality welding, handheld laser is unequivocally the better choice.

New Energy Battery Tray Welding

Tue, 27 Oct 2026 00:00:00 +0000

Background

EV battery trays require welding 1.0–3.0mm aluminum alloys (6061, 5052). Aluminum has high reflectivity and excellent thermal conductivity — traditional welding suffers from poor fusion, heavy spatter, and severe deformation. Laser welding solves all three.

Solution Specs

Item	Details
Machine Model	VELTRA™ MJ-15-BFL or MJ-20-BFL
Laser Power	1500W / 2000W
Shielding Gas	Nitrogen N₂
Welding Material	Aluminum alloy 6061 / 5052, 1.0 – 3.0mm
Welding Type	Lap joint, T-joint
Optional	Rotary welding head (for complex joints)

Key Metrics

Metric	Spec
Weld Width	≤ 1.5mm
Tensile Strength	≥ 70% of base metal
Deformation	Minimal, no post-weld straightening needed
Consistency	Stable mass production

Pressure Vessel Welding

Tue, 27 Oct 2026 00:00:00 +0000

Background

Pressure vessel manufacturing requires high-strength, porosity-free welds that strictly meet GB/T 150, ASME VIII, and other standards. Traditional multi-pass TIG/MIG welding on 3–5mm steel plate needs 3–4 passes — slow, prone to inter-pass slag inclusions, and high rework rate.

Solution Specs

Item	Details
Machine Model	VELTRA™ MJ-20-BFL handheld laser welder
Laser Source	2000W fiber laser
Wire Feeder	Auto wire feeder (standard)
Shielding Gas	CO₂
Welding Material	Carbon steel Q355, 3.0 – 5.0mm
Welding Type	Single-pass butt joint on vessel body

Key Results

Metric	Before (multi-pass TIG)	After (2000W laser)	Improvement
Passes Required	3 – 4 passes	Single pass	4x faster
Porosity Rate	~ 3% (inter-pass slag)	~ 0.2%	15x lower
UT Test Result	Meets GB/T 150	Meets GB/T 150	Same quality, double speed
Heat Input	High, pre-heat needed	Low, no pre-heat	Simplified process
