Argon-arc welding fixture for T-shaped components

Abstract

The invention relates to the field of argon-arc welding, in particular to an argon-arc welding fixture for T-shaped components. The argon-arc welding fixture for the T-shaped components comprises an upright column plate, a bottom plate, a left positioning barrier, a right positioning barrier and two gas guide pipelines. The upright column plate is perpendicularly arranged on the bottom plate, the left positioning barrier and the right positioning barrier are perpendicularly mounted on the upright column plate and are used for fixing a T-shaped component, the two gas guide pipelines are perpendicular to the upright column plate, the first gas guide pipeline is arranged on the lower portion of the T-shaped component, and the second gas guide pipeline is arranged at a position of a perpendicular included angle of the T-shaped component. A groove is formed in the bottom plate and corresponds to the positioning barriers, and the first gas guide pipeline is arranged in the groove. The T-shaped component is fixed onto the left positioning barrier by the aid of the right positioning barrier via a puller bolt which is mounted on the right positioning barrier. A plurality of gas holes are formed in the two gas guide pipelines. The argon-arc welding fixture has the advantages that the argon-arc welding fixture can be filled with argon via weld heat-affected zones, so that the shortcoming of quick oxidation of the surfaces of materials due to the fact that the surfaces of the materials are in contact with the air during hot processing can be overcome, and the performance of materials can be protected after the materials are subjected to hot processing.

Description

technical field [0001] The invention relates to the field of argon arc welding, in particular to a fixture for argon arc welding of T-shaped parts. Background technique [0002] Some metals will be oxidized when the temperature exceeds a certain temperature during thermal processing, which will increase the hardness and strength of the weld metal, while the plasticity will drop sharply, such as titanium alloy parts. Now T-shaped parts can be processed by milling and welding processes, but because some metal materials have the characteristics of high strength, high hardness, and high cost, they have higher requirements for milling and cutting processes, and it is easy to cause waste of materials. For processing T-shaped parts by welding process, ordinary T-shaped argon arc welding fixtures are mostly used now, but the heat-affected zone of the weld seam is completely exposed to the air during welding. Since welding will generate high temperature in the heat-affected zone of t...

Now processing T-shaped parts can be processed by milling and welding processes, but because some metal materials have the characteristics of high strength, high hardness, and high cost, they have higher requirements for milling and cutting processes, and it is easy to cause waste of materials

For processing T-shaped parts by welding process, ordinary T-shaped argon arc welding fixtures are mostly used now, but the heat-affected zone of the weld seam is completely exposed to the air during welding. Since welding will generate high temperature in the heat-affected zone of the weld seam, the material surface contacts Air will oxidize rapidly, affecting material properties
