Processing is possible with only spot operations! Achieving process reduction and cost reduction!
We would like to introduce the features of "dissimilar material welding (spring material × steel)" by Yokoyama Seiko Co., Ltd. The spot welding of spring steel (hardened material) typically involves a spot welding process followed by a tempering process. Therefore, by implementing secondary current (primary current = spot welding, secondary current = annealing) in the proposed spot welding process, we have made it possible to perform processing with only the spot welding process, achieving a reduction in the number of processes. *For more details, please feel free to contact us.
