Abstract
The present invention provides a welded member including a hot dip Zn-based alloy coated steel sheet as a base material and has excellent corrosion resistance and weld bead shear strength, and provides a method for manufacturing the welded member. In 5 a welded member (10) in which a lower sheet (3) and an upper sheet (1), which are hot dip Zn-based alloy coated steel sheets, are stacked and arc-welded together, a weld bead (2) is formed so that a cross-sectional width W satisfies the following formula (1) and a blowhole occupancy Br represented by the following formula (2) 10 b e c o m e s n o t m o r e t h a n 5 0 % : 2 T ≤ W ≤ 6 T ( 1 ) , B r = ( Ʃ di/L) × 100 (2), where T represents a thickness of hot dip Zn-based alloy coated steel sheet, di represents a length of i-th blowhole observed in X-ray radiography, and L represents a length of weld bead.
