ONE SIDE HORIZONTAL FILLET GAS SHIELD ARC WELDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a one side horizontal fillet gas shield arc welding method which has stable arc, is little in sputter generating quantity and obtains deep weld penetration even in a welding condition of high electric current and high speed. SOLUTION: This one side horizontal fillet gas shield arc welding method features that a flux cored wire which contains Si of 0.3-1.8%, Mn of 0.8-4.0% and an arc stabilizer of 0.05-1.8% with respect to wire total weight % of the wire where flux is filled into a steel cover and has a flux filling rate is 3-10% is used and the welding of the horizontal fillet part where a fillet angleθwith which an erected plate of the horizontal fillet member composed of an under plate and the erected plate is inclined is over 90 deg. is performed.
