RESISTANCE WELDING TRANSFORMERS
Resistance welding involves the controlling of electrical currents ranging from as low as 1000 amperes to has high as 250,000 amperes. The voltage that is required across the work piece to deliver this level of current is only around one volt. Resistance welding is an electromechanical process that is used to assemble metallic parts. A basic understanding of the electrical and mechanical components of the process will provide the foundation for developing control algorithms that benefit the users of this assembly method. It is a good practice to design welding tools beginning at the requirements of the weld nugget and progressing outwards to the controls
