PROBLEM TO BE SOLVED: To provide a wire for the gas-shielded arc welding capable of achieving the excellent wire feedability during the welding for a short period through a long period and performing the welding with consistent arc even when a long liner is used, and many bend parts are present. SOLUTION: A plurality of long grooves which are discontinuous in the longitudinal direction of a wire surface for the gas-shielded arc welding are formed in the circumferential direction of the wire. Molybdenum disulfide is fixed to the long grooves by 0.005-0.20g per 10 kg of the wire, and further, the feeding lubricant consisting of one or more kinds of lubricating oil which is liquid at normal temperature is deposited by 0.5-3.0g per 10 kg of the wire. The feeding lubrication contains 0.005-0.25g molybdenum disulfide and 0.008-0.10g phospholipid per 10 kg of the wire for the gas-shielded arc welding. COPYRIGHT: (C)2010,JPO&INPIT
