Case studies sample of Precision welding for molds. Shape recovery for blade edges. Our precision TIG welder allows us to carry out ultrafine padding. This is an extremely valuable type of welding which only a small number of technicians are capable of performing, even at Hashimoto Industry. Shape recovery through welding. Welding of padding within a given frame. Redesign by welding half-padding. Edge padding in a circular configuration. High-precision welding in a rib configuration.
