Handheld Fiber Laser Welding Machine 500–1500 W (MW-PW series)

Overview

The MW-PW series is a handheld fiber laser welder for thin sheet metal. The laser source, water chiller and control system share one cabinet on castors, so the machine takes little floor space and moves as one unit.

The operator holds a light torch on a 5–10 m fiber cable and moves it freely around the part. The continuous laser beam produces a narrow, even seam. On stainless steel the seam usually shows little discoloration and needs little or no grinding. With good fit-up, the weld is as strong as the base metal.

Four power levels cover different sheet thicknesses: 1 mm at 500 W, 1.5 mm at 750 W, 2 mm at 1000 W and 3 mm at 1500 W. Welding speed runs up to 120 mm/s.

Configuration

• Laser source: fiber laser, 1064 nm, continuous or modulated output, beam quality M² ≤ 1.1–1.2.
• Cooling: industrial water chiller with dual temperature control, built into the cabinet.
• Torch: handheld welding torch with interchangeable nozzles for different joint types.
• Fiber cable: 5–10 m, length chosen at order.
• Controls: touch screen and push-button panel on the cabinet, with a torch holder and cable hanger.

Typical applications

The machine welds carbon steel, stainless steel, aluminium and galvanized sheet. Typical work includes butt (tailor), lap and fillet joints, tube elbows and T-joints, handrails, pipe fittings and signage letters. Irregular shapes are easy to follow by hand.

Options and customization

• Power: 500, 750, 1000 or 1500 W.
• Fiber cable length from 5 to 10 m.
• Supply voltage and plug type to suit your country.

Every machine has a 2-year whole-machine warranty, and we train your operators free of charge at our factory in Wuhan.
