Abstract
A method for welding a galvanized steel sheet includes utilizing a pulse welding of repeatedly applying a pulse peak current and a base current, setting a welding speed to 100 cm/min or less, and using a shielding gas in which 1 vol % or more and 10 vol % or less of at least either one of CO2 and O2 is added to Ar. The pulse peak current has a pulse peak time being in a range of 7% or more and less than 50% of one period depending on a sheet thickness of the galvanized steel sheet.
