Dear teachers, can TIG welding be used for welding 304 stainless steel pipes (with water as the medium and a pressure of 0.5 MPa)?
Thread Content
Because MIG welding has a fast welding speed (it uses stainless steel wire and argon as the shielding gas), TIG welding was used in the past; now it is employed in order to increase speed.
:Lol, it can. . . It just has a bit more stomata
I guess it won’t work, and it’s also a pipe.
Since your medium is water, there’s no need for flaw detection; it should be fine!
It should be possible, depending on the welder’s skill level and the quality of protection; however, whether it can pass the radiography test still needs to be verified through that test
It seems that flux-cored wires cannot be used on the pressure-bearing components of pressure vessels and pressure pipelines
Passing by, coming to learn* a bit~~~
Is it a pressure pipeline? Flaw detection failure is not acceptable
Once welded properly, it won’t leak, but whether welding is possible depends mainly on the client’s requirements, the design specifications, and whether the welding process assessment is successful. This is MIG welding; as long as the welder does things properly, there should be no issues with inspections either
I have discussed with the management the use of TIG welding for the root layer and electrode welding for the finish layer, as this approach yields better results and helps reduce welding defects in later stages.
