- Study on Welding Process of Solid Phase Welding by Post Heat Treatment
抄録
The welding process of solid phase welding was investigated using the tensile shear load and micro structure of cold pressure welds of copper, aluminum and iron followed by post heat treatment at various temperatures and for various times. The results are as follows.<BR>1. The improvement process of the weld strength depends on post heat temperature, post heat time and welding deformation, and satisfies Arrenius' equation.<BR>2. A rise in the weld strength is based on a relief of residual elastic stress due to recovery at the initial stage of post heat treatment, and an increase of welded areas which depend on thermally activated diffusion along the weld interface with the advance of post heat time.<BR>3. The weld strength is determined by the combined effect of soundness of the weld interface and softening of the weld metal. The maximum weld strength is obtained at a certain time which depends on the base material, welding deformation and post heat temperature.<BR>4. At elevated post heat temperature, the weld strength which has decreased due to softening of the weld metal, increases again owing to the elimination of voids at the weld interface, and welding deformation does not seem to affect the weld strength.
