Publication number: 20200406385Abstract: A base material is welded by a first welding method in a case where a welding parameter related to heat input to the base material is less than a first threshold value. The base material is welded by a second welding method in a case where the welding parameter is less than a second threshold value and is more than the first threshold value. The base material is welded by a third welding method in a case where the welding parameter is more than the second threshold value. By adjusting welding conditions regardless of the thickness of the base material, a welding method suitable for the thickness of the base material is determined to provide a welding with little spatter and no meltdown of the base material.Type: ApplicationFiled: September 14, 2020Publication date: December 31, 2020Inventors: Atsuhiro KAWAMOTO, Kaito MATSUI, Masaru KOWA, Takahiro NOGUCHI, Masashi FUJIWARA
