Welding procedures?
(OP)
Is it ok to repair a 10" S40 CS A53-B pipe that was welded with 7018, with 70S Tig on the Cap? I was not given a Procedure for this Inspection, and was told that it was ok. I would like to know for sound of mind......

'Big'T is the total thickness of the basemetal being welded on. Does the proposed WPS have a thick enough upper limit to allow work on your thickness?
'Little' t is the total deposited weldmetal. Do not use this when evaluating whether your WPS will work for the repair. And again, ensure that the angle & width of the excavation is wide enough to fulfil the requirements of your WPS. Welders tend to leave the groove too narrow to meet the limits of a WPS.
