Abstract

PURPOSE: To enable welding defects to be non-destructively inspected simply and readily simultaneously with welding work by so constituting the apparatus that the welding condition of studs is checked from the welding time of the arc current measured and the effective value of arc current.
CONSTITUTION: The pilot arc current Ip detected in an input circuit 1 and the main welding arc current Iw from the welding current are supplied via attenuator 2 to a time measuring circuit and is waveform-shaped 3, after which these are amplified 4 and are supplied to a digital display device 5. Namely, the time from the time when the pilot arc current Ip was generated up to the point when the shortcircuit current Is at the arc quenching is detected is measured, stored and displayed. On the other hand, the output current from the attenuator 2 is supplied via effective value circuit 6 and amplifier circuit 7 to a digital display device 8, where the value of the welding arc current is digitally displayed. The storage contents of the display devices 5, 8 are released by the detection of the next pilot arc current, by which the apparatus is reset.
