Description

Technical Field

[0001] The utility model relates to a multi-size hot isostatic pressing component stand pipe sealing processing platform based on resistance spot welding technology, in particular to a multi-size comprehensive processing platform capable of sealing vertical steel pipes of hot isostatic pressing components of different specifications with a powder loading weight of 500-2500kg. Background Art

[0002] As the only channel for powder filling and vacuuming of hot isostatic pressed parts (casings), the reliable sealing of stainless steel pipes has an important impact on the quality of the final parts. In order to ensure the powder filling and convenient and reliable compaction of hot isostatic pressed parts (casings), there are special requirements for the position of stainless steel pipes for powder filling and vacuuming of hot isostatic pressed parts (casings) (i.e., they can only be placed at the top and center of the casing), which puts stringent requirements on the sealing method and supporting equipment of the casing.

[0003] Resistance welding technology has the advantages of high productivity, environmental protection, easy operation, small deformation, and no need for filler metal. It uses resistance heat as a heat source, which can quickly heat the local area in a short time to achieve fast welding; because it does not require gas protection or filler metal, it reduces the emission of harmful gases and pollution to the environment; the operation of resistance welding technology is relatively simple, does not require complex equipment and process flow, reduces the skill requirements for operators, and is easy to produce and maintain; because resistance welding technology uses local heating and pressurization to seal the welded workpieces, compared with fusion welding, it has the least impact on the powder purity and vacuum environment in the hot isostatic pressing parts (encapsulation), and is the best sealing technology.

[0004] However, due to the special position of the hot isostatic pressed component (jacket) riser and the high quality and high reliability requirements of the seal, there is currently no applicable general resistance welding supporting equipment on the market. Utility Model Content
