This sketch was drawn by an detailer that isn’t current with AWS welding symbols. I believe that is a safe statement because A2.4 was revised in 1976 and has required each side of the joint, i.e., arrow side and the other side, to be dimensioned separately ever since. Since that was 30 plus years ago, I believe it reasonable to say the detailer/engineer is “old” or at the very least “not current” and possibly “no longer relevant”.
That being said, I would interpret the symbol as specifying a CJP double bevel groove weld with 1/4–inch reinforcing fillets.
Haven’t we seen this recently from you Joe? It looks familiar. Going back to the original thread I do see it is the same question that was asked several months ago. My original response still stands, ask that the symbols be corrected and clarified so there is no question regarding interpretation. The detailer/engineer should be using current welding and NDT symbols per the most recent revision of A2.4, not one that is 30 years out of print.
One last comment, D1.1 has long stated that a weld without dimensions shall develop the full base metal strength in tension and shear. Reference clause 2.2.5.3 (D1.1-2006 as an example). The designer/engineer/fabricator would have detail the actual welds to develop the necessary strength. That is usually the design professional's responsibility. It is not within the welder's or the CWI's job descriptions to to take on those responsibilities.
