Good morning,
Please, I´d need to know the applicable standard for UT on A240 Tp 316L, 3/4" thick plates. I see that ASTM A578 is for rolled carbon and alloy steel plates.
Many thanks,
Good afternoon, please:
Can I have a prequalified WPS for the "subject" joint ( see Figure 3.4 of D1.1), considering 3.13.2 of AWS d1.1 and that this joint has been welded in the two different following manners but and in both cases without steel backing? ( joint is non tubular) :
1- welded...
ajh1 thaks for your answer.
Our situation, as erectors, is: we have received drawings specifying the torque value to be applied to all joints.
¿Do we need a pre-installation verification procedure? or ¿ is it just acceptable to apply the specified torque value to te bolts being installed?, thanks
ajh1, thanks for your answer. The question is only what the differences are relating to how the surface finish affects to the torque value, particularly: galvanized finish vs blueing finish, thanks
Good evening, please;
Is there any difference in torque value to be applied on a permanent steel structure joint for the same bolt ( e.g. A 325 . Diam 3/4")?, thanks
gtaw, thanks for your answer; the question is that we have not presently E6010 electrodes but we do have a PQR qualified 2 years ago with this E6010+E7018, thanks
Good evening, please just the following question:
Can a WPS planned with one SMAW filler metal ( e.g. E7018) be supported by a PQR tested with a combination of two of them - SMAW ones- ( e.g. E6010+E7018)?, thanks
