Abstract

PURPOSE: To practice a pressure welding with superior strength, by applying fine- grained powders of specific particle size as an inserting material between contacting surfaces of metallic materials and heating up all these materials to a temperature lower than a solid phase line of metallic materials.
CONSTITUTION: The particle size of fine-grained metallic powders is 1μmW1mm and the surface area of grained powders is about 10W100cm2/g. The sintering temperature of metallic powders is a little lower than that of the lump of same metal. Both contacting surfaces of metallic materials are finished by grinding and washed and a thin layer of the powdered mixture containing fine-grained metallic powders or fine-grained powders is applied on the contacting surfaces. Then, these materials are kept combined by pressure force so that both contacting surfaces be closely touched to each other. Sintering and diffusing actions will proceed when all materials are kept heated in a vacuum or an inert gas atmosphere at a temperature not higher than each solid phase line of the mother materials and inserting material, but higher than a sintering temperature of the fine-grained powder material. The proper grading of the inserting material is about 0.01W1.0mg/1cm2. Thus, the welded zone between metals is excellent in its strength, oxidation resistance, corrosion resistance and heat impact resistance and a residual strain can be minimized.
