JUNCTION METHOD OF EACH OTHER DIFFERENT QUALITY OF MATERIAL

摘要

PURPOSE: A junction method for different materials is provided to minimize energy consumption for junction by employing a low-heat input welding method. CONSTITUTION: A junction method for different materials comprises the steps of: manufacturing a first junction member out of a galvanized steel plate, manufacturing a second junction member out of an aluminum material, arranging the first and second junction members with ends thereof overlapped, and welding the first and second junction members through low-heat input welding using argon gas as protective gas.
