Procedure qualification in accordance with ASME SECTION IX
VIckers Hardness Testing in accordance with NACE MR0175
I am in the process of procuring plate material for a procedure qualification in accordance with ASME IX and Vickers hardness testing as well. My question is in regards to the size of plate needed in order to full fill the requirements of the mechanical, tensile, and hardness testing under the previously mentioned specification/codes. I do know the size of plate needed for a procedure qualification with mechanical and tensiles being the only testing but I’m questioning weather or not to add a couple inches to my test weld coupon or if the standard sizes mentioned under QW-462 “Test Specimen”, will be enough. Another question would be, when the lab is testing my welded test coupon, do they perform the hardness test to a cross section that would later be designated for a tensile test or vice versus? If that is the case then I suppose the minimum size recommended in ASME IX would be correct. The last thing I want to do is order the wrong size and get a call stating that all the testing needed cannot be performed do to not having the required amount of material. I have did my research, for example, I reviewed NACE MR0175, ASTM A384, and ASME IX and couldn’t find the answer to my question, oh yeah let’s not forget google. I already made a call to our local test lab but did not get to speak with anyone do to it being after hours. I figured I would ask on the forum, since I have had good luck in the past with having my questions answered and maybe it will help someone else out down stream.
