JFE Steel has developed new intelligent advanced welding technologies, such as intelligent spot welding and laser-arc hybrid welding for the assembly of an automotive body. Intelligent spot welding, which is a resistance spot welding technique using multi current and force control steps to form a sound nugget among triple-sheet jointing of larger sheet thickness ratio compared to a conventional resistance spot welding. Laser-arc hybrid welding, which is YAG laser welding combined with metal active gas (MAG) arc welding, enables expansion of the gap tolerance in lap welding up to nearly thickness of sheet to be welded and decrease blowholes in lap welding of zinc coated steel sheets.
