Abstract
In today’s manufacturing world spot welding and its quality control take especially in the sheet metal industry a big place. According to that, a sheet metal part group has been taken from an automotive supplier firm. Several spot welding parameters (force, current and time) have been applied to these parts. The parameter limits have been apartly applied to the certain test parts. After applying the chisel tests, the spot welding region dimensions have been measured. The strengths of these regions can be defined with tensile tests, too. A relationship between these determined nugget diameters, strengths, calculated empirical strength values and welding parameters can be created. Finally, the relationships can be explained with mathematical formulas, too. These examinations have been done to give limit values for a simulation research to find a relationship between distortions after spot welding and spot welding parameters. It has been checked and confirmed on the production line of the supplier firm that these limit parameter values have guaranteed the welding strength. Verbal observations for the relationships and exceptions by those will be achieved, too.
