Cladding process using gas metal arc welding as a heat source and 308L stainless steel wire as feedstock

Cladding technology in parts of manufacturing and repairing has been applied in many areas such as aerospace and automotive industries. One of the purposes of this technology is to prevent metallic surface from corrosion and wear. In order to reduce cost in tools and dies, layer-by-layer deposition...
