Abstract

PURPOSE: To enable welding defects to be simply and readily inspected simultaneously with welding work by a non-destructive method by displaying the output signal of the measuring circuit forming the integrated value of welding arc current and its welding time in a digital display device and detecting the welding condition of studs.
CONSTITUTION: The output signal of a shunt circuit 1 assuming an input circuit for detecting the welding current from a welding condenser is supplied via attenuator 2 to an integrator circuit 3. In the circuit 3, the arc currents are subsequently integrated and added by a so-called mensuration by parts from the pilot arc current generating point t0 up to the pressing point tn of a stud to a base metal. Namely, in order to obtain t0I0+t1I1+...TNIN=ΣtI, the welding is started by detecting the arc current at t0 and is stopped by detecting the shortcircuit current Is at tn, then ΣtI is calculated. Next, the output of the circuit 3 is amplified 4 and is stored in a digital display device 5. The operator views the value displayed digitally 5 and checks whether it is within the intended allowable range or not.
