Re: [MW:24244] Above ground storage tank

Dear Tahir,

The purpose behind using backing strip is to provide the support to the weld pool to penetrate properly and to avoid the access back gouging.It may be the ceramic or metallic it may be permanent or temporary.

If you dont want to do the RT so can replace RT with UT and You may offer to your client the Root and final DP also.

This is for your info and further action.
