Vertical Strip Clad Welding Method and Apparatus

Abstract: 

Method and apparatus for vertical strip clad overlay welding. The method comprises matching the vertical travel of a special welding shoe to an appropriate amount of strip electrode melt-off necessary to maintain a preset molten pool level within a reservoir trough provided by the shoe. The welding shoe comprises a water cooled copper mold for forming the weld bead and a ceramic insert connected to the mold for providing the reservoir trough. Apparatus for correlating the vertical travel speed of the shoe with the strip electrode melt-off is disclosed. Apparatus for applying a plurality of successive weld beads to a vertical vessel wall is also disclosed.
