Seam Welding Wheel, Seam Welding Wheel Electrode - Seam Welding ...A seam welding wheel is a spinning, motor-driven wheel-shaped electrode used in resistance seam welding to create a continuous, leak-proof seam on metal parts by making a series of overlapping spot welds. These wheels apply pressure and electric current as they roll along the workpiece, generating heat to melt and fuse the metal together in a continuous line, similar to a sewing seam.
