FLW technical specifications

FLW laser sources are rated from 1,000 to 3,000 W. Source output instability is below 3% under the specified test conditions of 25°C and at least 5 hours of continuous operation. Use a trial weld on your material to check joint quality.

Welding inputs

Choose the process for your joint

Power alone does not define a weld. Review material, joint, fit-up, filler, access, duty and inspection together.

Material and joint

Provide alloy, coating, thickness, joint type, seam length, access and target penetration/fusion.

Fit-up and filler

Record gap, edge preparation, wire, bead appearance, distortion and strength/leak criteria.

Duty and utilities

Define power, gas, cooling, fibre length, extraction and electrical supply.

Safety and validation

Confirm controlled access, reflection hazards, training, PPE, fume extraction and sample coupon.

Product systems

Inside the handheld welding system

The FLW setup combines a laser source, handheld head, process control and cooling. Select it around the material, joint access and required weld result, together with the planned workstation.

Laser source and fibre delivery

Laser source

Select output for the welding task

The FLW range lists 1000–3000 W sources with continuous or modulated operation.

Choose power against the intended material and joint, then validate the result with a weld sample.

Handheld laser welding head and cable connection

Fibre delivery

Connect the source to the handpiece

The fibre package delivers the source output to the handheld head.

Match fibre core and cable length to the selected machine and workstation.

Oscillating welding head

Control the path at the seam

The handheld head combines beam oscillation, nozzle positioning and shielding-gas delivery at the joint. Head access affects how the operator can follow the seam.

Review nozzle, optics, joint access and the intended material. Oscillation settings and the process recipe belong to the selected head and welding package.

Gas, wire and process control

Control panel for a handheld laser welding system

Shielding gas

Supply the specified gas

Shielding gas forms part of the welding recipe at the joint.

Select the gas and parameter range for the intended joint and supplied package.

Wire-feed unit and feed line for handheld welding

Wire feeding

Configure filler delivery when required

The 2026 FLW configuration uses a four-roll, dual-drive automatic wire feeder for 0.8–1.6 mm filler wire.

Select the filler alloy and wire diameter for the joint. Retraction at weld stop and a programmable feed delay coordinate the wire with the weld cycle.

Laser welding control panel with process settings and machine controls

Process control

Coordinate the welding recipe

The controller coordinates laser output and oscillation with gas and any wire feeding.

Review stored recipes and which control functions are included in the machine.

Source and optics cooling

Cooling system used with an FLW handheld laser welding machine

Match cooling to the operating duty

The 2026 FLW configuration has an integrated industrial water chiller with two temperature-control circuits for the laser source and optics.

Check the ordered source power, ambient temperature and cooling connections when sizing the workstation.

Workstation and operator protection

Workstation

Define the complete welding area

Plan the working area, extraction and controlled access around the intended process.

Define site responsibilities alongside the supplied equipment and installation scope.

Operator protection

Review the protection arrangements

Handpiece safety functions, interlocks, protective equipment and training form part of the installation review.

Confirm the supplied functions and operator requirements for the intended work.

Material and joint trial

Evaluate the required weld

A representative seam brings the source, head, wire or no-wire process, gas and operator access together. Inspect the weld against the intended joint requirement.

Agree material, joint preparation and the visual or measured acceptance criteria. Evaluate the delivered recipe and workstation conditions used for the trial.

Process and safety boundary

FLW configuration and workstation planning

Set the welding process for your alloy, joint and fit-up, then verify it on a representative sample.

Rated Process Data

Use the FLW parameter table for rated power, mode, adjustment, wavelength, modulation, optical and fibre values.

Configured equipment

Source, cooling, head, spot mode, wire feeder, optics, gas and enclosure depend on the selected process.

Acceptance checks

Approve coupons for material, joint, gap, penetration, appearance and inspection, then complete the laser-safety assessment.

Before start-up

Installation and commissioning
