Abstract

PURPOSE: To obtain defectless good arc welded zone, in the case of fillet welding depending on the gas shielded arc welding, etc., by empolying the automatic welder which can program control the suitable welding condition.
CONSTITUTION: The desired leg legth L (mm), arbitrary welding speed WS (mm/ min)and the length of wire extension EXT (mm) are inputted to the digital input device, and the welding current I (A) is obtained from the formula; in which, ρ is the density of material g/cm3, K and K' are constants depending on the shielding gas and the wire. In the meantime, the arc voltage V, proportional to above current I, is obtained by inputting the length of wire extension EXT into the digital input device and by the relation between current and voltage for case of previously actually measured extension EXT, that is uaually 7.5DW18.75D where D is the diameter of the wire. According to this method, the suitable current and voltage are displayed in the welder and are controlled, and the conventional preliminary examination for welding becomes unnecessary, and the quality of the weld zone is improved.
