    WPQ w/charpy requirements

    Thank you all for your respond. Yes, I know what welding standard we are working for. It’s tech.pub. 248. And I have a one more questions. In this standard in the table VII is missing a group of material S-11D (HSLA-100). May be some one has an email or a letter from the NAVY about this mistake...

    WPQ w/charpy requirements

    Does anyone knows, if I have a HSLA-100 3/4" steel, should I do a charpy test for a welding procedure qualification? If Yes what standard I should use? Thanks
