Hi there, anytime I make an engineering drawing with welds I try to use the most accurate symbols possible. With this particular setup up though I am not sure which symbol to pick. See the attached file. I have a piece of metal slotting into a rectangular hole and then I wish to effectively do a rectangular slot weld. When bringing an initial prototype to the welder he just called it a plug weld. Just want to confirm what symbol I should use. The circled area is the area of interest.
