Abstract
PURPOSE: To obviate the occurrence of a lack-of-fusion defect between the deposited metal and works by providing a thermal buffer layer composed of the metal of the specific heat conductivity on the surfaces to be welded thereby performing welding.
CONSTITUTION: Sn being metal of the heat conductivity lower than that of base metals 3 is attached by a gas burner on the surface to be welded at the V-grove of the works 3. This is preheated to melt excess Sn which is then removed by a brush or the like, whereby a thin and even thermal fubber layer 4 is provided. If MIG welding is done in this state, the cooling of welding metal becomes slow, as a result of which the lack of fusion is not observed at all in the weld zone and Sn single phase is undiscernible. Copper brazing material, etc. besides Sn, Zn, etc. used for the main components of copper alloy are property used for the metal for forming the layer 4. The methods of forming the layer 4 include chemical plating, plasma spraying, etc.
