Handheld fiber laser welding machines can weld a wide range of metals with high precision and minimal heat distortion. They are particularly suitable for materials with thicknesses of 0.5 – 12mm, commonly used in industrial manufacturing. The maximum welding thickness depends on the laser power, with higher-power machines providing deeper penetration and stronger welds.
Suitable for approximately 0.5–10 mm thickness, fiber laser welding produces clean, narrow weld seams with a small heat-affected zone, making it ideal for stainless steel structures, food equipment, and pressure vessel components. To learn more about the equipment, see: Laser Welding Machine for Stainless Steel
Applicable for 0.5–12 mm thickness, fiber laser welding ensures deep and consistent penetration with strong joint strength, widely used in construction machinery, metal fabrication, and steel structural parts. To learn more about the equipment, see: Laser Welder for 12mm Carbon Steel
Suitable for 0.5–8 mm thickness, optimized laser parameters help reduce porosity and deformation, enabling stable, high-quality welds for automotive parts, lightweight frames, and aluminum products. To learn more about the equipment, see: Aluminum Laser Welding Machine
Suitable for thin to medium-thickness copper components, fiber laser welding requires carefully selected laser parameters due to copper’s high reflectivity and thermal conductivity. Common applications include electrical connectors, busbars, heat exchangers, and conductive components.
In addition to the common welding materials listed above, there is also welding equipment specifically designed for aluminum-steel and galvanized steel. To learn more about these materials, check out Kempson welding machines.

KEMPSON fiber laser welding machines serve manufacturers working with sheet metal, metal components, machinery, and fabricated assemblies. The equipment type and power rating should match the part geometry, material thickness, weld appearance requirements, and production volume.
Welding metal cabinets, electrical enclosures, doors, frames, panels, and custom sheet metal products.
Welding stainless steel sinks, kitchen equipment, appliance housings, worktables, and metal fixtures.
Joining metal brackets, housings, structural parts, and selected aluminum components. Automated systems suit repeatable welding paths and batch production.
Welding machine frames, supports, brackets, equipment housings, and fabricated metal assemblies. Higher-power models can be considered for thicker workpieces.
Manufacturing stainless steel furniture, shelves, railings, display fixtures, and decorative metal products where weld appearance and dimensional control matter.
Welding steel structures, agricultural machinery parts, thick plates, and heavy equipment components. High-power configurations should be selected against the actual material thickness and joint requirements.
Fiber laser welding offers a high-precision, high-speed, and non-contact alternative to traditional welding methods such as MIG, TIG, or arc welding. It produces narrower weld seams, smaller heat-affected zones, and minimal distortion, making it ideal for thin metals, precision components, and automated production lines. In contrast, traditional welding methods often require more post-processing, generate higher thermal impact, and may be less efficient for repetitive or delicate applications.
| Feature | Fiber Laser Welding | Traditional Welding (MIG/TIG/Arc) |
|---|---|---|
| Precision | High, narrow weld seams | Moderate, wider welds |
| Heat-Affected Zone | Minimal | Larger, may cause distortion |
| Speed | Fast, suitable for automation | Slower, labor-intensive |
| Material Flexibility | Thin to medium metals, alloys | Wide range, but less ideal for thin sheets |
| Surface Finish | Smooth, minimal post-processing | Often requires grinding/polishing |
| Non-Contact | Yes, reduces mechanical stress | No, contact may deform workpiece |
| Environmental Impact | Cleaner, low fumes | Produces smoke, spatter, and more post-processing waste |

Selecting a fiber laser welding machine requires matching the equipment to the workpiece, welding process, and production requirements.
Choose the laser power according to the metal type, workpiece thickness, joint structure, and required penetration. KEMPSON offers models across a 1000W–6000W range. Actual welding capacity should be confirmed through model specifications and sample tests.
Air-cooled and water-cooled models have different equipment structures and thermal management requirements. Compare cooling capacity, operating conditions, duty cycle, and maintenance requirements for the specific model.
Wire feeding may be necessary for wider gaps, filler-metal requirements, or particular joint designs. Confirm wire diameter, feeding modes, weld bead requirements, and compatibility with the intended material.
Check the power supply, installation conditions, operator training, warranty, spare parts, and after-sales support. For customized or automated systems, confirm the work area, fixtures, control configuration, and production cycle before ordering.

A fiber laser welding machine joins metal parts using a concentrated laser beam. It is used for stainless steel products, carbon steel components, aluminum parts, sheet metal fabrication, automotive components, machinery, and industrial metal assemblies.
The required power depends on material type, thickness, joint design, and welding speed. KEMPSON offers models from 1000W to 6000W. Sample welding tests can establish suitable power and process settings for the intended workpiece.
Common materials include stainless steel, carbon steel, aluminum alloy, galvanized steel, copper, and selected metal alloys. Material grade, surface condition, reflectivity, and thickness affect weld quality and process selection.
Air-cooled machines use air-based heat dissipation, while water-cooled models use a liquid cooling circuit. The appropriate option depends on laser power, operating duty, ambient conditions, equipment design, and maintenance requirements.
Yes, selected high-power models can weld thicker metal sections. The achievable thickness depends on laser power, material, joint preparation, welding configuration, and process parameters. Confirm the required thickness through technical specifications and sample tests.
Handheld machines allow operators to guide the welding head manually and suit varied workpieces. Automatic systems use programmed motion, fixtures, or CNC platforms for repeatable welding paths and production processes.
Not every application requires filler wire. Thin materials and suitable close-fitting joints may be welded without wire, while wider gaps or specific joint designs may require filler metal. Wire diameter and feeding configuration should match the welding process.
Provide the material type, workpiece thickness, joint design, required welding speed, production volume, and preferred machine type. KEMPSON can assess the application, recommend a suitable configuration, arrange sample welding tests where available, and provide a quotation based on the confirmed specifications.
