Four Laser Functions in One Machine

1. Handheld Laser Welding

Handheld laser welding uses concentrated fiber-laser energy to melt and join metal along a controlled weld path.

Compared with many conventional welding processes, the focused energy can provide a narrow weld seam, smaller heat-affected zone and reduced workpiece deformation. The handheld gun allows operators to process butt joints, lap joints, fillet joints and inside or outside corners.

The machine supports welding with or without filler wire, depending on joint fit-up and application requirements.

2. Auxiliary Thin-Metal Cutting

The handheld cutting mode can perform limited cutting of compatible thin metal sheets using the correct nozzle, assist gas and operating parameters.

This function is intended for occasional trimming, fit-up adjustment and auxiliary workshop cutting. It does not replace a dedicated CNC fiber laser cutting machine for precision profiles, automated nesting, repeatable dimensions or volume production.

3. Remote Surface Cleaning

Remote cleaning uses a wider scanning pattern to remove suitable rust, oxide layers, paint and surface contaminants from metal.

It can be used for:

  • Pre-weld surface preparation

  • Rust removal

  • Oxide removal

  • Paint and coating removal

  • Oil and contaminant removal

  • Maintenance and restoration

Cleaning results depend on the coating type, thickness, adhesion, laser power, scan width and required substrate condition.

4. Weld Seam Cleaning

Weld seam cleaning uses a narrower processing area to remove discoloration, oxide and residue from a completed weld.

It is intended for localized post-weld finishing and can help prepare welded parts for inspection, painting or coating.

Surface Cleaning vs Weld Seam Cleaning

Function Surface cleaning Weld seam cleaning
Main purpose Clean a wider metal surface Clean a localized welded joint
Typical use Rust, oxide, paint or contamination removal Post-weld discoloration and residue removal
Processing width Wider scanning area Narrower, weld-focused area
When used Before welding or during maintenance After welding
Optical setup Remote-cleaning configuration Weld-seam-cleaning configuration
Limitation Not a replacement for high-speed dedicated laser cleaning Intended for localized finishing

The supplied optics, lenses and nozzles must match the selected operating mode.

  • Material and alloy

  • Joint design

  • Joint gap and fit-up

  • Welding position

  • Laser power

  • Welding speed

  • Focal position

  • Oscillation width

  • Filler-wire type

Metals the Machine Can Process

Stainless Steel

The system can weld stainless steel cabinets, sinks, kitchen equipment, enclosures, frames and decorative components. Correct shielding gas and parameters help limit oxidation and discoloration.

Carbon Steel and Mild Steel

Carbon steel and mild steel can be welded with or without filler wire, depending on material thickness, joint fit-up and strength requirements.

Galvanized Steel

Galvanized steel requires appropriate surface preparation, process control and fume extraction. Heating the zinc coating can generate hazardous fumes and increase the risk of porosity.

Aluminum and Aluminum Alloys

Suitable aluminum alloys can be welded using the correct power, filler wire, shielding gas and surface preparation. Aluminum generally requires more careful parameter control than carbon steel or stainless steel.

Copper and Brass

Some copper and brass applications may be possible, but results depend strongly on material reflectivity, alloy composition, thickness and laser-source configuration. Sample testing is required.

Handheld Laser Welding Methods

Butt Welding

Joins two workpieces along adjacent edges. Consistent part fit-up is important when welding without filler wire.

Lap Welding

Joins overlapping metal sheets and is commonly used for cabinets, enclosures and sheet metal components.

Fillet Welding

Joins two surfaces positioned at an angle, including common T-joint applications.

Inside-Corner Welding

The handheld gun provides access to internal corner joints when the torch, nozzle and workpiece geometry allow.

Outside-Corner Welding

Suitable for external corner seams on cabinets, boxes and fabricated metal products.

Autogenous Welding

Autogenous welding uses no filler wire and is suitable when the joint has a close and consistent fit-up.

Filler-Wire Welding

The automatic wire feeder supplies additional material to bridge gaps, improve bead formation or meet weld-strength requirements.

Intelligent Automatic Wire Feeder

The wire feeder delivers filler wire at a controlled rate and can help improve weld consistency.

It is recommended when:

  • Joint gaps are present

  • Additional weld material is required

  • A wider weld bead is needed

  • Part fit-up varies

  • Repeatable filler-wire delivery is important

  • Dissimilar material thicknesses are being joined

Common wire diameters may include 0.8mm, 1.0mm, 1.2mm and 1.6mm, subject to the supplied feeder, guide tube and nozzle.

Wire material must match the base metal and welding requirements.

Wobble Welding Technology

The handheld welding head moves the laser spot in a controlled oscillation pattern.

Wobble welding can help:

  • Increase effective weld width

  • Improve gap tolerance

  • Distribute heat more evenly

  • Control penetration

  • Improve weld seam appearance

  • Reduce the risk of localized overheating

Oscillation width, frequency and pattern must be set according to the material, thickness, gap and welding speed.

Digital Process Control

The control system allows the operator to select an operating mode and adjust relevant parameters.

Depending on configuration, adjustable parameters may include:

  • Laser power

  • Welding speed

  • Scan width

  • Oscillation frequency

  • Wire feed speed

  • Gas delay

  • Laser delay

  • Start and end settings

  • Material presets

  • Cleaning width

  • Cleaning speed

Only trained operators should change process parameters.

Why Choose an Air-Cooled Laser Welder?

No External Water Chiller

The cooling system is integrated into the machine and does not require a separate cooling-water unit.

Smaller Footprint

Removing the external chiller reduces the overall equipment footprint and simplifies workshop placement.

Easier Transport

The compact design makes the system easier to relocate between work areas or transport for suitable on-site applications.

Simplified Cooling Maintenance

Operators do not need to replace coolant, clean a water tank or inspect an external water circulation loop.

No Coolant Leakage or Freezing

Air cooling eliminates risks associated with coolant leakage, contamination and freezing. The machine must still remain within its specified environmental limits.

Faster Installation

Installation requires electrical power, grounding, gas or compressed air, ventilation and a controlled laser work area, but no external chiller connection.

Air-Cooled vs Water-Cooled Laser Welders

Factor Air-cooled laser welder Water-cooled laser welder
Cooling system Integrated air cooling Water chiller and cooling circuit
Portability More compact and easier to move Typically larger and heavier
Cooling maintenance No coolant replacement Requires coolant-system maintenance
Installation Simpler cooling setup Chiller setup required
Coolant leakage risk None Possible
Cold-environment risk No coolant freezing Freeze protection may be required
Best suited for Portable, flexible and space-limited work Demanding high-power or extended-duty production
Selection factors Power, duty cycle, temperature and dust Power, duty cycle, temperature and cooling capacity

The correct choice depends on the actual workload, ambient temperature and operating duration.

Laser Welding vs TIG and MIG Welding

Factor Handheld laser welding TIG welding MIG welding
Typical speed High for suitable joints Lower Medium to high
Heat-affected zone Relatively small Larger Process-dependent
Thin-sheet deformation Generally lower More likely Process-dependent
Filler wire Optional Commonly used Commonly used
Weld appearance Narrow and clean with correct settings High quality but slower Depends on settings
Post-weld finishing Often reduced May be required May be required
Operator requirements Laser and process training Skilled TIG operator Skilled MIG operator
Safety controls Class 4 laser controls Arc-welding controls Arc-welding controls

Laser welding is not automatically the best process for every joint. Irregular gaps, dirty material, inaccessible welds or one-off repairs may still favor conventional welding.

No. It uses an integrated air-cooling system and does not require an external water chiller or coolant circuit. This reduces the machine footprint and eliminates coolant replacement, leakage and freezing issues.

What Is the Difference Between Surface Cleaning and Weld Seam Cleaning?

Surface cleaning uses a wider scanning area to remove rust, oxide, paint and contamination from a metal surface. Weld seam cleaning uses a narrower processing area to remove localized discoloration and residue after welding.

Which Metals Can It Weld?

The machine can weld compatible stainless steel, carbon steel, mild steel, galvanized steel and aluminum. Some copper and brass applications may also be possible. Results depend on material grade, thickness, joint, gas and process parameters.

What Is the Maximum Welding Thickness?

Maximum welding thickness depends on laser power, material, joint design, gap, welding speed, filler wire and required quality. The final capacity should be confirmed with a material-specific test instead of relying on a single universal thickness value.

Can It Weld Aluminum?

Yes. Suitable aluminum alloys can be welded using the correct laser power, shielding gas, filler wire and surface preparation. Aluminum generally requires more careful parameter control than carbon steel or stainless steel.

Can It Weld Without Filler Wire?

Yes. Autogenous welding without filler wire is possible when the joint has a close and consistent fit-up. For larger gaps or applications requiring additional weld material, the automatic wire feeder is recommended.

Which Wire Diameters Are Supported?

Common configurations support 0.8mm, 1.0mm, 1.2mm and 1.6mm wire. The exact range depends on the supplied feeder, guide tube, drive rollers and welding nozzle.

Which Shielding Gas Should I Use?

Argon is commonly used for stainless steel and aluminum. Nitrogen or approved compressed air may be suitable for certain carbon-steel or cleaning applications. Gas selection, purity, pressure and flow must match the material and process.

Can It Remove Heavy Rust and Thick Paint?

It may remove rust, oxide and coatings, but cleaning performance depends on contamination thickness, adhesion, laser power and scan settings. Heavy corrosion or large-area thick coating removal may require a dedicated pulsed laser cleaning machine.

How Wide Is the Cleaning Area?

Cleaning width depends on the cleaning lens, focal length, scan configuration and operating parameters. Heavth should confirm the available cleaning width for the exact gun and optics included in the quotation.
