Seam welding electrodes are generally in the form of wheels and are referred to as seam welding wheels or rolls. We supply Mipalloy seam welding wheels in Cr.Zr.Cu. Materials. However Ni.Si.Cr.Cu. wheels are available on request. For best results and to ensure lower down times seam welder shafts & housings must be made of Cr.Zr.Cu. Seam welder wheels supplied by us are in proof machined & fully machined condition. All seam welding wheels are manufactured out of individually forged blanks
