Abstract
An arc welding quality evaluation apparatus for consumable electrode gas shielded arc welding comprises a heat input detection means for detecting heat input applied to a workpiece to be welded; a welding time detection means for detecting the welding time of the workpiece; a spatter weight detection means for detecting the weight of spatter produced during the welding time of the workpiece; a heat compensation means for compensating for heat loss due to spatter occurring during the welding time of the workpiece; an effective heat input computation means for computing effective heat input per unit welding time, based on detected values of the detection means and , and a compensation value of the heat compensation means ; and a weld quality assessment means for comparing an output of the effective heat input computation means to a reference standard value, and assessing weld quality acceptability based on the degree of separation of the computation means output from the reference standard value.
