Abstract

The invention relates to the technical field of welding processes, and aims to solve the problem of deformation of precise parts during welding. The welding process for the precise parts comprises thefollowing steps of a, clamping the precise parts; b, heating; and c, carrying out constant-temperature welding. In the step a, at least two precise parts far away from the required welding surface are abutted against each other and clamped; in the step b, the precise parts and to-be-welded parts are heated to 60-70 DEG C; and in the step c, the precise parts and the to-be-welded parts keep at a constant temperature of 60-70 DEG C, and the precision parts and the to-be-welded parts are welded. The surfaces of at least two precise parts far away from the required welding surfaces are abutted against each other and clamped so as to generate mutual restraint, the welding surface is smoother, strong rigidity fixing constraint is generated, and the deformation amount is reduced.
