An arc welding quality evaluation apparatus for consumable electrode gas shielded arc welding comprises a heat input detection means 8 for detecting heat input applied to a workpiece to be welded; a welding time detection means 11 for detecting the welding time of the workpiece; a spatter weight detection means 16 for detecting the weight of spatter produced during the welding time of the workpiece; a heat compensation means 17 for compensating for heat loss due to spatter occurring during the welding time of the workpiece; an effective heat input computation means 12 for computing effective heat input per unit welding time, based on detected values of the detection means 8 and 11, and a compensation value of the heat compensation means 17; and a weld quality assessment means 22 for comparing an output of the effective heat input computation means 12 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.
An arc welding quality evaluation apparatus suitable for a consumable electrode gas-shielded arc welding, wherein a welding voltage is applied between a welding wire and a workpiece to be welded, molten metal droplets from the welding wire are transferred to the workpiece, and that portion of the wire consumed by the transfer of droplets is replenished, for performing continuous arc welding, the apparatus comprising:
