200KVA Automatic Longitudinal Circular Seam Welder Product Description working principle During the seam welding joint formation process (intermittent) seam welding, each welding spot also has to go through three stages of pre-compression, electric heating and cooling and crystallization. However, due to the rapid change of the relative position between the roller electrode and the weldment during seam welding, these three stages are not as obvious as the distinction during
