KEMPSON handheld laser welding machines are designed for welding metal sheets and components in industrial fabrication. Fiber laser technology produces concentrated heat at the weld joint, reducing the heat-affected area and post-weld grinding compared with conventional TIG and MIG welding under suitable welding conditions.
The handheld laser welding machine range includes air-cooled all-in-one units, water-cooled industrial models, and systems with built-in gas generation. Power selection depends on the workpiece material, thickness, joint design, and production requirements. Selected configurations support welding thicknesses from 0.5 to 12 mm, with penetration depth and weld quality subject to the machine model and welding conditions.
As a handheld laser welding machine manufacturer and supplier, KEMPSON offers equipment with power options from 1000W to 6000W. Custom configurations are available for laser power, cooling system, wire feeding, gas supply, and machine structure to suit different production environments and workpiece requirements.
Whether you need a compact air-cooled machine for on-site fabrication or a water-cooled system for continuous production, KEMPSON can configure a suitable solution for your application. Contact us to discuss your welding requirements, arrange sample welding tests, and request a detailed quotation.
A handheld laser welding machine is a compact, user-friendly welding system that uses a fiber laser source to deliver high-energy beams for precise metal joining. Also known as a handheld laser welder or portable laser welding machine, it offers fast welding speed, minimal heat distortion, and clean weld seams with little post-processing. This type of equipment is ideal for on-site repairs, small-batch production, and thin metal sheet fabrication, making it widely used in industries such as metal processing, maintenance services, and light manufacturing.

KEMPSON handheld laser welding machines support stainless steel, carbon steel, and aluminum alloy. Selected models also support copper and galvanized sheet. The suitable laser power depends on the material, plate thickness, joint design, and required weld quality. Use the published specifications as a starting point, then verify the welding process against the actual workpiece.
| Laser Power | Stainless Steel | Carbon Steel | Aluminum |
| 1500W | 2.5 mm | 3 mm | 2 mm |
| 2000W | 5 mm | 5.5 mm | 4.5 mm |
| 3000W | 7 mm | 8 mm | 6 mm |
| 4000W | 11 mm | 12 mm | 10.5 mm |
Values are based on KEMPSON model specifications for fillet welding. Actual results depend on joint design and welding parameters.
| Laser Power | Welding Thickness | Fillet Weld Width | Single-Side Weld Height |
| 4000W | 0.5–10 mm | 11 mm | 7 mm |
| 6000W | 0.5–14 mm | 11 mm | 8 mm |
Joint types: Fillet, lap, and butt joints require different process settings. Confirm the joint design, plate gap, and required penetration through sample welding tests before production.
Joint design affects penetration, weld formation, and the required process parameters.
Before choosing a machine, provide KEMPSON with the material grade, plate thickness, joint drawing, gap tolerance, and required weld appearance. Sample welding tests can assess penetration, bead shape, spatter, deformation, and the need for filler wire under the proposed settings. For production-critical parts, evaluate the test weld against the project’s acceptance criteria before confirming the machine configuration. This is particularly important for aluminum, thick plates, tight dimensional tolerances, and joints with inconsistent gaps.
Contact KEMPSON to discuss your workpiece requirements, arrange sample welding tests, and select a laser welding machine for your application.
