Laser Deposit Welding
High Quality Repair On-Site
Laser repair or processing of molds can be done on site and requires only minimal pre and post-processing, and achieves material qualities matching new condition. The laser welds a hand-guided filler wire onto the workpiece with spot-accuracy and high strength. Surface applications with wire diameters of 0.1 mm to 0.8 mm can be realized. A very local heat-affected zone, rapid heating and cooling, exact control of the beam power energy via pulse shaping – all these factors provide a minimum thermal load on the workpiece. For crack-sensitive material the mold does not need to be pre-heated.
The tilt-adjustable processing optics allows to process even vertical surfaces, narrow geometries or complex areas without rotating or tilting the mold. In many cases, easy past-processing of the weld seam with e. g. a drawing die is sufficient. Experience has shown that a laser deposit welding system pays off short-term, even when only used occasionally. This applies for the manufacturer (who saves complex, expensive and time-consuming transports of damaged molds as well as repair costs caused by external subcontractors) and specialized jobshoppers alike
