    Hello all, attached is two screenshots of the same part. We need help deciphering the weld callout type is correct or not. In the photos, the blue outline are the object lines of the part and the yellow is the actual weld itself. There is a large gap between each flanges (roughly 9.53mm / 3/8"). We just need clarification on the callout but we plan to request a change.

    The groove weld symbol shown would require the edges to butt against each other. Since the drawing shows a gap, that gap should be specified.

    This should also help. I don't think the square groove weld symbol is appropriate. The Full Open Corner looks more appropriate. With the gap in your product, that would also need to be specified.

    The weld type would essentially have to change as well to potentially a Fillet weld style, is that correct?

    How thick is the metal on your product? The full open corner with a fillet weld is normally used on heavier metal thicknesses. The half open corner is used for 12 gage and higher). Thinner metal sheets (20 gage and lower) would use a Flush Corner groove weld. See Corner Joint Welding: All You Need To Know (mewelding.com)

    That should put it in the full open corner with fillet weld. Welds A, C and D are all options.

    I am going to propose style D. I feel like the gap is too large and will have burn through.

    Thanks for the help! I will keep this information for future reference.
