Re: [MW:7937] golden weld joint require ments

Dear Mr. Khader,

If you are looking for 'Golden welds' you may not find it in any codes because it is a slang used in the industry. Look in para 345.2.3 (c) of B31.3:2006, you will find 'Closure Welds'. That is it.

The requirements are 'in-process inspection' as given in para 344.7 plus RT or UT. Please do not forget to generate suitable reports to all steps given in 344.7.1 to satisfy the purchaser.

Always remember that NDT is not an alternative for Pressure test.

Mr Gulam

I could remember the following things for Golden weld.

a) It means, other than of fabrication shop welding, the balance welding which will be done with only one joint at site welding( or)in a tie -in work process. This type of joints are confirmed by 100% RT or UT (NDT), since there may be a practice problem in the hydro test depends with the pipe length.

b)There is no specific code for Golden joint but most of the companies are follow to perform a "golden weld", with 100% NDT by eliminating hydro test.

c) We can refer ASME 31.4, and it permits a "waiver" of a hydro test on "tie-in" welds between two sections of piping, that the weld has already undergone 100% NDT (see Section 437.1.4 (b) Testing Tie ins, ASME B31.4 2002 Edition).
