PURPOSE:To prevent the defective feeding of a rectanuglar solid wire for semi- automatic gas shielded metal arc welding and to obtain a satisfactory bead by specifying the relation between the thickness and width of the sectional shape of said wire. CONSTITUTION:The thickness (t) of the sectional shape of the solid wire for arc welding formed into a rectangular shape is made 0.4-0.8mm. and said wire is so formed that said thickness has the relation W/t=5-2 with the width W thereof. Said wire is so formed as to have 110-150kg.f/mm.<2> tensile strength. Such wire has adequate ruggedness and is therefore fed satisfactorily without buckling in a conduit tube when used for semi-automatic gas shielded metal arc welding. In addition, the arc stability during welding is improved and the broad bead having excellent appearance is formed. |
