PURPOSE: To certainly keep measured data even if trouble is generated in a memory means by providing a means measuring a welding time and an average current and a means writing the measured data by the measuring means in a detachable memory means. CONSTITUTION: When data is recorded on recording paper and desired to be left, welding data is printed by a printer 27. A field worker confirms the welded state of a pipe member and a joint member on the basis of the printed welding data. The welding data is also stored in an IC card 25 other than a memory 24 and the IC card 25 is extracted from an external memory device 20 to be kept. By this constitution, even when the memories 9, 24 of an electric welding apparatus or external processor 20 get out of order, the welding data can be certainly kept. |
