Abstract
The invention discloses the welding procedure of a kind of powder metallurgy support and 1215 steel pipes, comprise the following steps：Powder metallurgy support and 1215 steel pipes interference fit, soldering paste is applied in support and pipe fitting joint；Powder metallurgy support and 1215 pipes are put into brazier, it is whether effective by the detection checking welding of tensile strength through taking out weldment after a period of time, the effect of welded seal is confirmed by test of hunting leak.The invention provides a kind of technique of welding, make the sealing engagement of metallic sintered products and 1215 steel pipes firm, and can produce in batches.
Description
Technical field
The present invention relates to a kind of welding procedure, and in particular to a kind of welding procedure of powder metallurgy support and 1215 steel pipes.
Background technology
Nowadays, metallic sintered products are suitable for batch production, are suitable for cutting few machine components, energy-conservation saves material, no dirt
Dye.The connection of metallic sintered products and other parts is inevitable internal because powder metallurgy manufacture craft result in it with is also generalized
Hole is certainly existed, so as to influence thermal conductivity, thermal expansion, hardenability makes weld failure.
The content of the invention
Goal of the invention：The present invention is directed to deficiency of the prior art, proposes a kind of raising product quality, reduces scrappage
The welding procedure of powder metallurgy support and 1215 steel pipes.
Technical scheme：The welding procedure of a kind of powder metallurgy support and 1215 steel pipes of the present invention, including following step
Suddenly：
A, powder metallurgy support and 1215 steel pipes interference fit；
B, in powder metallurgy support and 1215 steel pipe joints apply soldering paste；
C, powder metallurgy support and 1215 pipes be put into soldering oven；
It is D, whether effective by the detection of tensile strength checking welding；
E, the effect by test confirmation welded seal of hunting leak.
Further, step（B）The component proportion of described soldering paste is：Red copper：Nickel：Manganese=60%：30%：10%.
Further, step（C）The temperature setting of the soldering oven is：400-500 DEG C of preheating, 900 DEG C of heating chamber, progressively
It is raised to after 1100 DEG C, 20 minutes, temperature is cooled back to 60 DEG C to 100-200 DEG C, the time altogether is 70 minutes.
Beneficial effect：The present invention improves product quality, adds the tensile strength and sealing of welding, meanwhile, batch
Production, it is cost-effective.
