Reply:assuming your testing to API1104, here's a link to an older version of the standard. It's out of date, but the infor you're looking for is probably still valid.http://www.scribd.com/doc/17391067/API-1104starts on page 8 for butt joints, and goes from there. Tells you where the test straps are cut from the pipe, how many of each you need for each test, etc.The bend straps are ground flush for root and face bends, so far as I know. Nick-breaks are not ground at all. Transverse tensile specimens are ground smooth on the sides, but the root and face are left as welded. Impact specimens and all -weld metal tensile bars are completely machined to exact finished dimensions.Benson's Mobile Welding - Dayton, OH metro area - AWS Certified Welding Inspector |
