Kemppi FastBeam 3 – 3 kW Handheld Laser Welder

High-speed handheld laser welding for high-volume production

The Kemppi FastBeam 3 is a Finnish-made 3 kW handheld fibre laser welding machine designed for industrial production. It combines high-speed welding with precise beam control, guided parameter setup, integrated welding data and layered safety features, all in a practical system designed around the welder.

The concentrated power of the 3 kW fibre laser delivers high welding speeds and deep penetration while maintaining a narrow heat-affected zone. By limiting heat spread around the weld, FastBeam 3 helps reduce thermal distortion, rework and post-weld finishing, so you can produce high-quality welds faster and spend less time correcting or finishing each workpiece.

Adapt the laser to each welding job

Materials, joint geometries and production requirements vary from job to job. FastBeam 3 gives you greater control over how laser power is delivered to the joint.

Penetration Shape Control lets you adapt the laser beam to each application by adjusting its shape, balance, wobble and power. Beam wobble width can be set from 0 to 5 mm, with a frequency of 20 to 200 Hz, giving you precise control over penetration and weld profile across different materials and joint designs.

This flexibility helps welding professionals apply high-speed laser welding to a wider range of production tasks.

Set up faster with Weld Assist

A new welding process should support production, not slow it down. Weld Assist helps you find suitable laser welding parameters quickly and easily, reducing setup time for new jobs. FastBeam 3 also makes handheld laser welding easier to manage and document in industrial production.

Stable performance with external water cooling

A high-capacity external chiller provides the cooling required by the water-cooled 3 kW laser power source and LT3 welding torch. It helps maintain controlled operating temperatures and stable laser welding performance during demanding production work.

With 5 m and 10 m cooling hose options, the chiller can be positioned outside the laser welding enclosure. This reduces heat and noise in the working area and gives you greater flexibility when planning your production layout.
