A "golden joint" refers to a weld joint that is usually the final weld connecting existing piping to new piping and the joint will not be pressure tested. Since the weld joint will not be pressure tested, NDE is performed in lieu of pressure test. Many owners only want the best welders to weld these joints because NDE is not nearly as good of a test method as hydrostatic or pneumatic pressure testing.
A “golden weld” or “golden joint” is a weld that cannot be hydrotested (because it’s the final weld on site, or there’s refractory behind the weld, or …). The consequence is that this weld is 100% NDT inspected, usually with several different techniques (UT, RT, MT, PT, …). Because of the cost of these multiple 100% NDT inspections, it’s called “golden”.
Golden Joint mean Tie in Joint. Normally it will come on Piping final
joint . in this joint after welding you can not test hydrostatic test.
So you have to go for double NDT for volumetric such as RT / UT and MPT
/ DPT .
After successfully carrying out these tests you can release the
joint for charging lines.
I’ve never heard the phrase, however, I expect that it refers to the oxide layer which forms on a properly inert-gas-shielded TIG weld, which can be a golden color, sometimes with purple hues. This is especially true of welding on stainless steel.
