Laserschweißen

Laser welding of stainless steel

Laser welding can be used to weld extremely fine, delicate components and structures very cleanly and with minimal distortion. Almost all metallic materials, from aluminum to steel to titanium, can be welded.

The low heat input and high cooling rates of laser welding usually result in the welded material being stronger than the base material. It can be used to create very fine, narrow weld seams with high load-bearing capacity.

The laser beam can be precisely adjusted to produce a reproducible welding depth of a few tenths of a millimeter.
The achievable temperature cycles in the material also allow the welding of materials that cannot be welded conventionally.

Laser welding of stainless steel is a task performed daily at innojoin. The stainless steel alloys that are laser welded range from simple V2A to high-alloy stainless steels.

Complex geometries and inaccessible welding points are well suited for laser welding.
From manually guided lasers to automated robot cells, innojoin can carry out individual repairs of injection molds and solid forming tools, as well as laser welding of pipes several meters in length

All innojoin processes are documented in welding instructions prepared in accordance with ISO 15609-4. Many of the welding instructions are additionally approved and released by TÜV or other classification societies at innojoin.

For fine weld seams with extremely low heat input, innojoin uses a pulsed Nd:YAG laser. Three laser systems with articulated arm robots and rotary axes are connected to diode lasers and disc lasers with a laser power of 4 to 8 kW.
