发明名称 METHOD FOR PRODUCING ARC-WELDED Zn-Al-Mg ALLOY COATED STEEL PLATE STRUCTURAL MEMBER
摘要 A method for producing an arc-welded Zn—Al—Mg alloy coated steel plate structural member excellent in liquid metal embrittlement cracking resistance is provided. The method contains a step of joining steel members by gas-shielded arc-welding to produce a welded structural member, at least one of the steel members to be used is a hot dip Zn—Al—Mg alloy coated steel plate member, and the shield gas contains an Ar gas, a He gas or an Ar—He mixed gas as a base gas with a CO2 concentration controlled in a range of from 0 to 7% by volume.
