High frequency induction welding simulating on ferritic stainless steels

This work aims to develop and evaluate a piece of equipment to simulate high frequency induction welding of ferritic stainless steels using a conventional power supply for resistance spot welding. Modifications were performed in the power supply to allow but welding of thin sheet and variation of process parameters like sheet width, welding time and current. Tests were performed to evaluate the use of this equipment. The results were evaluated by visual inspection, tensile testing and metallographic analysis. The analysis indicates that good-quality welds, which are similar to those obtained by high frequency welding, may be obtained.
