Case studies sample of Precision welding for molds. Welding of padding within a given frame. This welding is carried out within a certain area that has been marked off. We use precision laser welders to weld padding down to the hundredths of a millimeter. Shape recovery through welding. Shape recovery for blade edges. Redesign by welding half-padding. Edge padding in a circular configuration. High-precision welding in a rib configuration.
