    摘要： A stable penetration depth and a reduction in spatter can be simultaneously achieved in an arc welding method where forward feeding and reverse feeding of a tip of a wire are periodically repeated. A total period of the forward feeding period (TP) and the reverse feeding period (TN) is set as one cycle and a frequency f of one cycle is set as 50 to 150 Hz, a relationship between an average current (IP-AVE) of the current non-suppression period (TIP) and an average current (IB-AVE) of the current suppression period (TIB) is set as 0.65 ≤ IP-AVE / (IP-AVE + IB-AVE) ≤ 0.90, a wave height (Wh) that is a variation width of the tip position of the welding wire between the uppermost end and the lowermost end is set as 14 to 35% with respect to a distance between the tip of the welding wire and the base metal, a relationship between any current non-suppression period (TIP) and the current suppression period (TIB) immediately after the current non-suppression period (TIP) is set as 0.30 ≤ TIB / (TIP + TIB) ≤ 0.60, a relationship between the forward feeding period (TP) and the reverse feeding period (TN) is set as 0.40 ≤ TN / (TP + TN) ≤ 0.70, a relationship between the current non-suppression period (TIP), the current suppression period (TIB), the forward feeding period (TP), and the reverse feeding period (TN) is set as {TN / (TP + TN)} > {TIB / (TIP + TIB)}, and the current non-suppression period (TIP) is controlled to account for 2/3 or more of the forward feeding period (TP).
