Can carbon steel be welded using sub-argon arc welding?
Thread Content
There is a valve whose seat is made of carbon steel, and four stainless steel screws need to be welded onto it. Can TIG welding be used for this? (The welding rod is made of stainless steel.) This post was last edited by jyszyx on 2009-4-2 at 10:42.]
TIG welding is a welding method that uses welding wire; in the case of welding different types of steel, the key lies in the selection of welding materials.
If both the valve seat and the screw are made of weldable materials, it is completely feasible; the key is to choose the right welding wire, with low-carbon stainless steel welding wire generally being an appropriate option.
It’s completely possible, as long as the right welding material is chosen. TIG welding has specialized welding wires
Yes, for welding carbon steel and stainless steel using TIG welding, H1Cr24Ni13 wire can generally be used.
Carbon steel can be welded using TIG welding; it’s just necessary to use a suitable welding wire, and the relevant standards can be consulted for this
It’s completely possible, but it’s not recommended. Based on experience, TIG welding involves a high heat input, which leads to significant deformation of the valve seat; it’s better to use welding electrodes and a lower welding parameter to weld, as this helps to control the deformation of the valve seat effectively :)
