Laser Welding of Aluminium with or without filler material

Joint welding and repair welding

Pulsed laser welding has many advantages over high-power laser welding and TIG welding. Starting from a batch size of 1, we are able to process your components without big costs for clamping fixtures. High welding speed, slightest thermal warping, non-porously and visually appealing welds can be ensured, while oxidation can be eliminated.
Short service routes and smooth communication provide the basis for superb welding results. Design, fixture construction, mechanical workshop, and welding department are together under a single roof at KURIOS, so that we are always able to react to requests as quickly as possible.

Non-ferrous metal processing with highest flexibility for material thicknesses of up to 3 mm.

Laser welding of aluminium with filler materials is perfectly possible. In a limited number of cases secure joints can be ensured even without the filler material. Depending on the requested welding diameter, we will use single-pass or multiple-pass welds.
The main advantage pulsed laser welding has over other welding procedures is that the heat input is extremely low, which makes exceptionally tight geometric dimensioning and tolerancing feasible.
We have the technology and the necessary know-how. Benefit from that! We are looking forward to your request regarding laser welding. Please get in touch with us.
