Sub-merged arc welding working in the heavy current and high temperature working environment, which is request contact tips have very good wear resistance and good electrical conductivity.
HOSO develop the new technology of SAW welding contact tips. Our contact tip is designed by copper tungsten faced with back casting HOSOCU202 shank. Our product has both advantage of CuW wear resistance and CuCrlZr. Refer to our submerged arc welding contact tips catalogue.
