Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.
[0025] Example. A kind of diffusion welding method of tin bronze and steel welding structure, it is characterized in that, carry out according to the following steps:
[0026] ①Multiple components are processed according to the drawings, and the welding surfaces of the multiple components are degreased and derusted, and then assembled to form a welded assembly. The multiple components include steel substrates, tin bronze plates and closed end caps;
[0027] ② Put the welding assembly into the middle of the lower support plate in the furnace of the vacuum diffusion welding equipment, and separate the welding assembly and the support plate with graphite paper;
[0028] ③ Control the vacuum degree in the vacuum diffusion welding equipment at 1.0×10 -3 ~1.0×10 -4 Pa, by heating and pressurizing;
