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
Repair and Modification with Reconditioned Quality as well as Wear and Corrosion Protection
Laser Deposit Welding
During the laser deposit welding process, also known as laser cladding, a filler material such as wire or powder and the basic material are melted by laser radiation and metallurgically bonded.
Laser deposit welding with filler wire allows repairs to be made, wear resistance can be improved, small design modifications can be realized and manufacturing faults can be corrected. All this can be done with excellent quality and flexibility which can only be achieved by laser technology. The laser beam makes a precise and high-strength connection between the manually added filler wire and the workpiece. Application areas with wire diameters of 0.1 mm to 0.8 mm can be realized. The low heat input, rapid heating and cooling, and precise control of laser beam energy by pulse forming all help to minimize thermal loading of the workpiece. Compared to other methods, the microstructural transformation in the workpiece is clearly lower.[/vc_column_text][/vc_column][/vc_row]
