| description | To provide a welding device of a plated steel sheet and a welding method of a plated steel sheet which do not require special pre-processing for a plated steel sheet that is an object to be welded, facilitate operation on a heating condition, and can suppress generations of air bubbles and sputtering.SOLUTION: A welding method of a plated steel sheet for welding a first plated steel sheet and a second plated steel sheet in an overlapped part in which the first plated steel sheet and the second plated steel sheet overlap each other includes: a first heating step of heating and melting the first plated steel sheet in a thickness direction of the first plated steel sheet from an outer surface of the first plated steel sheet in the overlapped part, and forming a molten metal pool of the first plated steel sheet in the overlapped part; and a second heating step of heating and melting the second plated steel sheet from an outer surface of the first plated steel sheet together with the molten metal pool formed in the overlapped part, and connecting the molten second plated steel sheet and the molten metal pool.SELECTED DRAWING: Figure 4
【課題】溶接対象のめっき鋼板に特段の前加工を必要とせず、加熱条件の操作が容易であり、気泡、スパッタの発生を抑制することができるめっき鋼板の溶接装置及びめっき鋼板の溶接方法を提供する。【解決手段】第１めっき鋼板と第２めっき鋼板を重ね合わせて生じる重ね合わせ部位において第１めっき鋼板と第２めっき鋼板とを溶接するめっき鋼板の溶接方法であり、重ね合わせ部位において第１めっき鋼板の外表面から第１めっき鋼板の厚さ方向に向けて第１めっき鋼板を加熱溶融して重ね合わせ部位に第１めっき鋼板の溶融金属プールを形成する第１加熱工程と、重ね合わせ部位に形成された溶融金属プールとともに第１めっき鋼板の外表面から第２めっき鋼板を加熱溶融して溶融した第２めっき鋼板と溶融金属プールと接続する第２加熱工程とを備える。【選択図】図４ |
