Abstract

Device for the continuous roller-welding of a longitudinal seam in metal tubes, esp. steel tubes, using resistance butt welding with direct current (D.C.) at high density and low voltage. The electrode roller consists of two discs with opposite polarity, sped. by a groove contg. insulation. The novelty is the use of a grinding wheel made of non-conducting material, which can be fed into the periphery of the roller to maintain a profile matching the outside dia of the tube being welded; and a dressing tool which can swivel through 180 degrees is employed to dress the profile of the grinding wheel. The electrode roller is pref. power driven. The electrode roller can be employed over very long periods while its profile is continuously maintained by the dressed grinding wheel.
