METHOD FOR ASSEMBLING AND WELDING HIGH-TEMPERATURE MECHANICAL, COMPONENT BY LIQUID PHASE DIFFUSION

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a metal precision mechanical component by liquid phase diffusion welding in assembling the mechanical component internally having complicated and precise pipe lines for carrying liquid and lightening weight. SOLUTION: In the method for assembling and welding the high-temperature mechanical component by the liquid phase diffusion welding, when the mechanical component which is divided into at least two or more is welded by liquid phase diffusion welding and is assembled, the divided surfaces are finished into surface roughness of 100μm or less, moreover a butting gap between the divided surfaces having surface roughness is set to 1 mm or less in the whole welding surface and assembling is performed. Thereafter, the divided surfaces are mutually welded by liquid phase diffusion.
