Dear expert, As per ASME sec-9 , QW-202.2 para C , We can proceed SS-316L Material GTAW, FILLET WELD PROCEDURE QUALIFICATION, please suggest me if macro test is applicable for this requirement. Because my job is only fillet weld small bore socket type welding required for my scope of work. Fillet‐weld procedures so qualified may be used for welding all thick- nesses of base metal for all sizes of fillet welds, and all dia- meters of pipe or tube in accordance with Table QW-451.4. Nonpressure‐retaining fillet welds, as defined in other Sections of the Code, may as an alternate be qual- ified with fillet welds only. Tests shall be made in accor- dance with QW-180. Limits of qualification shall be in accordance with Table QW-451.3. Kindly update ASAP.

I suppose this is a structural material. Rerolling does not reduce the Material Thickness and it is done to obtain uniform curvature and does not induce any stresses. In structural material, even Flame straightening below 600 deg C is permitted. Just for a precaution, you can have the L-seam RT tested after rerolling.

Dear Helmy,  If your plate is SA 36 then you can refer to SA6 where an under tolerance is provided which is 0.01 of an inch.  However, I suggest you have a word with your design engineer & enquire about the minimum design thickness, if the design thickness is 9.75 mm then there is no need to worry about it & the plate can be accepted.

What is your plate material specification?  Material specification always refers to General specification requirements for plate size, dimensions, straightness as well as physical & mechanical properties. For example if your material is SA 516 then you can find general requirements in SA 20 for all the tolerances and deviations.

Hi Mr. Ahmed, Thanks for your response. I do agree with the first point, but have a different opinion about the second point. If I am taking re-test specimen from same mother plate from which initial test was failed, it is more stringent for me as I am taking a risk of re-failure and subsequent testing of each pipe it the test fails again I am having in total ten mother plates (and 40 daughter plates) under same heat  Since API is referring in statement as 'should' it is not mandatory to take the re-test specimen from other mother plates  Kindly advise.
