An arc-welding method of a fusion Zn system plating steel plate excellent in a welding outside view and weld strength, a manufacturing method of a welding member, and a welding member

摘要

a method for arc welding a hot-dip galvanized sheet steel (1, 1?) where the average voltage current is 100? 300 a; the average welding voltage is 20 to 35 v, the waveform is a waveform current including a peak current and an alternately repeated base current in a 1? 50 ms, a plated layer of hot dip galvanized sheet steel (1.1 ') has a composition comprising zn as the main component and containing 1.0'. 22.0 5 by mass of al, and the amount of plated deposition w is 15? 250 g / m2.
