| titleOfInvention | Process method for improving pressure intensity of diffusion welding surface of each layer of sheet type corrugated pipe |
| abstract | The invention provides a process method for improving the pressure intensity of each layer of diffusion welding surface of a sheet-type corrugated pipe, which comprises the steps of S1, processing to obtain an annular welding diaphragm; s2, processing to obtain an annular inner compensation diaphragm and an annular outer compensation diaphragm; s3, spraying solder resist on the non-diffusion welding area of the annular welding membrane through a template: s4, installing an annular welding diaphragm, an annular inner compensation diaphragm and an annular outer compensation diaphragm in a diffusion welding tool according to a certain sequence, then placing the annular welding diaphragm, the annular inner compensation diaphragm and the annular outer compensation diaphragm into a vacuum diffusion furnace, and completing diffusion connection in the vacuum diffusion furnace according to certain diffusion welding parameters; s5, removing redundant sizes of the diffusion welded product and the finished product by a diffusion welding post-machine to obtain the corrugated pipe meeting the size requirement; and S6, placing the finished product after the step S5 into a vacuum furnace for stress relief treatment. The invention increases the pressure intensity of the diffusion welding surface, improves the rigidity of the corrugated pipe, and solves the problems of easy deformation, unstable product size, waste of raw materials, large working hour consumption, high rejection rate and low production efficiency in the traditional processing. |
