Case studies sample of Precision welding for molds. Edge padding in a circular configuration. Mold edges and angles tend to get damaged easily. In this photograph, we have carried out edge padding in a circle using 0.1 mm solvent. After finishing, this technique allows edges to be restored. Shape recovery through welding. Shape recovery for blade edges. Welding of padding within a given frame. Redesign by welding half-padding. High-precision welding in a rib configuration.
