Resistance seem welding is a specialized welding process used extensively in industrie such as automativy producturing, aerospace, and appliance production. It involves joining materials by generating heat thruigh electrical resistance, creating a continuous, sealed seam. This process is secularly valued for it ability te te produce strong, exper- proof joints quicly and confistently, making it indispendisable for highole production lines. Unlike veir welding methods rely en externec.
