For three types of pressure vessels, what welding wires, electrodes, and fluxes should be used?
Thread Content
For the three types of pressure vessels made of 304L and 316L respectively, what types of welding wires, electrodes, and fluxes should be chosen? I would appreciate the guidance of all the experts
Take a look at the welding manual – it specifies exactly what type of electrodes, wires, and flux should be used. I don’t have the book with me right now, but it explains everything in detail.
Welding rods, welding wires, welding fluxes: 304, A107, H0Cr1Ni10, HJ260, 316, A207
Welding rods, welding wires, welding fluxes: 304, A107, H0Cr21Ni10, HJ260; 316, A207, H0Cr19Ni12Mo2, HJ260 – these are not the only options
The welding procedures for JBT4709 steel pressure vessels are described in detail
Base metal Welding rod Welding wire Flux 304L A002(E308L-16) H00Cr1Ni10 HJ172, HJ151 316L A022(E316L-16) H00Cr19Ni12Mo2 HJ172, HJ151 See HG20582
Selection is based on JB/T4709; for manufacturers, it is also possible to rely on their own welding procedure evaluations.
304 and 304L are different from 316 and 316L; the presence of the letter \"L\" indicates a lower carbon content, while the presence of the letter \"H\" indicates a higher carbon content. The level of carbon content affects the material’s performance at various temperatures. Generally, materials with a higher carbon content exhibit better performance at high temperatures. Therefore, when choosing welding materials with the \"L\" designation, it is essential to select those with a low carbon content.

There is no inherent connection between the welding materials used and whether the container belongs to category three; it depends on the material of the container as well as the manufacturing requirements!! For details, refer to the specifications. This post was last edited by www557 on 2009-2-10 at 22:48.]
