Abstract

PURPOSE:To weld the corner of a box without thermal distortion easily and surely, by welding a side plate in one direction, fixed with a fixed electrode to side plate in other direction in pressing with a pressurized electrode, when making a box with the raw material of a thin metal expansion plate. CONSTITUTION:A notch 7 of a specified angle alpha is formed at four corners of a rectangular expansion plate 5 and formed to a folded body at chain lines l. This is clamp-fixed so as to form one side lateral side plate 11 to a box 9 with a fixed electrode 17 and spot welding is made so as to weld the longit-dinal side plate 13 of other direction at a butt part 15 while pressing on the side plate 11 end with a pressing cylinder 21. In this case, either sequential welding at each one corner or simultaneous welding of four corners is available.
