WELDED MEMBER FOR PLATED STEEL PLATE EXCELLENT IN WELD ZONE POROSITY RESISTANCE AND FATIGUE PROPERTIES AND METHOD FOR MANUFACTURING THE SAME

Abstract:

Disclosed is a welded member for plated steel plate having excellent weld zone porosity resistance and fatigue properties and a method of manufacturing the same. The welded member for plated steel plate having excellent weld zone porosity resistance and fatigue properties according to an embodiment of the present invention comprises a weld metal portion formed by arc welding and overlapping a first member and a laminated second member so as to partially overlap the first member, wherein the toe angle (.theta.) of the weld metal portion is 45.degree. or less, and the first member and the second member are plated steel plates.
