Dear,
pls refer  Sec IX QW-194 VISUAL EXAMINATION —
PERFORMANCE test coupons shall show no cracks and complete joint penetration with complete fusion of weld metal and base metal.

So  your performance test coupon was fail due to lack of penetration so additional test coupon is required as per sec IX. and why you test this failed test coupon for procedure.

Dear Experts

In our company are in process of pipe to pipe  SS316  MOC  Procedure and welde  rqulification  Pipe dia 250 X12thickX150L  Each pice  joined with MIG process, Visually  and also after RT   clearly says Lack of penetration even Though our Internal inspector recommended to go for Mechanical test,

In mechanical they have cut the pieces  where ever the LOP was not there in the weld joint, Portion was taken and results are meeting the valves .

Here this way can we accept this as procedure ,process and welder has passed the test as pe ASME Sec IX.

I need Experts opinion    on this.

Regards
