Beanspruchungsgerechte Formgebung von Umformwerkzeugen durch formgebendes Plasma‐Pulver‐Auftragschweißen

Load adjusted shaping of forming tools using build‐up PTA welding For the improvement of the mechanical‐technological properties of the forming tools (in particular medium sized component‐geometries) the build‐up plasma deposition‐welding was established as a manufacturing process. It could be proven that the thermo‐mechanical characteristics of these tools are improved by using of cobalt and nickel basis alloys. With the embedding of carbides in the cobalt basis matrix the most endangered surface regions of the tools may to be better protected and the life times significantly increase compared with the up to now with conventional materials manufactured components. With manufactured and tested segments of a transverse‐rolling tool it was possible to validate whether the won knowledge is transferable into the practice.
