Laser deposition- and repair welding

Form and tool maintenance with laser repair welding

With our flexible pulsed Nd-Yag laser we are able to weld laserspots with a diameter of 0.2–2.0 mm. Therefore we are in the position to repair small cracks or large areas of stamping tools or injection molding tools. With the turn and tilt objective together with the rotary axis modul we perform horizontal to vertical rotations for a completely welding process.

Laser deposition welding with wire additive

During the manual welding process a wire additive is positioned by hand to the welding area. In this way we build up material point by point, line by line or layer by layer to the desired geometry. With post processing like polishing, turning, milling or EDM we reconstruct the original shape of the tool.

Which materials are repairable with our repair welding process?

We repair tools made of materials like mild steel and tool steel, heat treatable steel, stainless steel, cast steel and cast iron, alumina, copper and copper alloys, titan and silver.

Do we monitor the welding process during the laser repair welding?

For control and observation of the welding process, we use TV-systems and lenses with an enlargement of 1:16. A stream of aragon or nitrogen protects during the welding process all parts against oxidation.

What kind of wire additives are on stock for laser deposition welding?

We have wire additives on stock for laser welding materials like mild steel and tool steel, heat treatable steel, stainless steel, cast steel and cast iron, alumina, copper and copper alloys, titan and silver. In general we have wire additives with a diameter of 0,1 – 0,6mm on stock.
