Weld Purging Post Weld Heat Treated (PWHT) Pipework

Welding processes can weaken metals by imparting residual stresses into a material, leading to a reduction in corrosion resistance properties. Post Weld Heat Treatment (PWHT) is regularly used to retain the strength of a metal when welding certain materials including high strength stainless steel and chromium-molybdenum (chromoly) steel such as P91. Temperatures during PWHT might reach as high...

Weld Purge Dams for Dished Ends and Short Pipes

Weld Purging (back purging) describes the removal of oxygen from the vicinity of a weld before, during and after welding. For pipe and tank welding of stainless steels, titanium and chrome steels, it is good practice to restrict the area required to be purged, usually with an inflatable tandem weld purging system. For the purging of short pipe pieces and dished end or dome end welds however, the...
