  • Method of hardfacing vertical walls
    Patent number: 4539460
    Abstract: A method of hardfacing vertical walls comprises building up a layer of superimposed partly overlapping horizontally extending weld beads by depositing the beads in a submerged arc welding operation using relatively thin welding wires and welding powder which is fed over the weld wire. The welding powder is allowed to accumulate to provide a support for additional powder as welding progresses vertically.
