<p>A butt weld is made between components having scarves. Three work stations AB, CD and EF advance from right to left, all in a non-oxidising atmosphere. AB, a plasma scarf melting step, precedes and is overlapped by CD, a spray deposition step, which applied a molten spray of filler metal to form the weld. THe step CD precedes and is overlapped by EF, a peening step, which consolidates the weld as it freezes. The peening EF does not overlap the scarf melting AB.</p> |
