I have a project with A500 Grade B/C square tubing weldments followed by stress relief. I'm trying to determine what grades of A500 apply in clause 3.14 (2) where the base metal shall not be cold worked and there is reference to A500 tubing. There aren't any other specific references to go on, not even in the product specification. I would assume that square tubing is sufficiently cold worked in manufacturing that this applies.
My aim is to use prequalified WPS. I'm wondering if anyone has had any similar experience prequalifying PWHT with A500?
