Influence of Welding Force on Dynamic Resistance in Spot Welding

Popis výsledku v původním jazyce

This paper focuses on the effect of contact force on dynamic electrical resistance in resistance spot welding which effects amount of heat generated in time. Methods for welding parameters monitoring and signal processing are presented. Changes in the positions of significant peaks (corresponding to certain events during the welding cycle) with increasing forces (1,3 – 3,8 kN) are used to describe resistance curves. The diameters of the weld nuggets were measured and the correlation with the peaks was evaluated. The results show that the welding force has a significant effect on the dynamic resistance curve shape and affects final weld size. Spot weld analyser with given method for signal processing used in this study has proven to be useful for measuring dynamic resistance signals during different welding forces.
