METHOD FOR QUALITY ASSURANCE FOR A SPOT WELDING SYSTEM AND TO CERTAIN COMPUTER

摘要

A method of quality assurance for a welding system in which a particular module is composed of individual parts by spot welding, in such welding cells (2,3,4) (x) welding points (21) set and according to predetermined rules drawn specimens for the evaluation of welds are, consists in the following steps: a) the welding points (x) of a specimen (y) are tested by means of a mobile testing apparatus (11), b) the test values ​​are stored in a computer (11; 13) evaluated by welding defect categories (u) be assigned, at the same time representing a weighting, c) for each welding point (x) and each sample (y) category (u) and number (z) of the welding cell (2,3,4) in the computer (11, 13) stored , d), these data are shown in which the diagnostic category corresponding number (u) is plotted for each sample for the (y) samples for each welding point (x) in a first mask (22).
