Abstract

The paper deals with the influence of the main welding parameters of resistance spot welding on the quality of the joint. The influence of the parameters was investigated within the range of welding area where satisfactory welding is expected (according to EN ISO 14373). DOE analysis was used as an analytical tool. The DC06 deep-drawing steel, 0.7 mm thick, used in the automotive industry was used as the base material. Quality was assessed by visual testing, ultrasonic testing, macroscopic and shear tests. The results shown that, in the area of optimized welding parameters, the welding current has a well-defined effect on the quality of the weld joint and the size of the welding nuggets. The results can be used to predict the size of the welding nugget depending on the set welding parameters.
