ABSTRACT:
A method is presented for metal bonding of a base metal by creation of a weld puddle by means of an air cooled gas-tungsten-arc torch.
As the puddle is created, the filler metal is fed as a wire into the puddle by means of a cold wire feed mechanism. The torch is automatically moved across the base metal in a longitudinal direction. The filler metal is deposited as the torch transverses the base metal. At the end of each stroke, the base metal is automatically indexed radially to the width of the weld bead. The process is continued until the bearing journal has been completely covered with filler metal to the required thickness.
In a disclosed preferred method, the filler metal is a tin, antimony, copper babbitt alloy which is bonded to a bronze metal for bearings.
