I have attached a screen shot of a HSS frame structure. The tube is 4"x3"x1/4". There are many joints, but this particular joint is giving me a hard time to detail. I have searched around and have found nothing conclusive on how to annotate this joint on a drawing.
There are 2 types of welds to ensure that a weld bead is placed around the entire tube, a fillet weld where the faces are perpendicular to each other and then a flare-bevel weld (red arrows on image) where the round of the tube meets back up with the end face of the opposite tube.
Do I need to apply 2 separate weld symbols for this type of joint or is it understood in most fabrication shops if a simple fillet weld symbol is placed.
If I placed two separate weld symbols on a joint like that, I would probably get a call from my shop floor to explain myself. They would be looking for a fillet weld symbol with leg length and the all around symbol. If it was a shop dealing with aviation equipment two symbols and note would be required.

So your shop can interpret what needs to be done in those types of cases. But to be safe, Should I annotate that weld with 2 different weld symbols? I just wasnt sure what the second weld symbol should be where the end face of the tube meets up with the round of the opposite tube. It would be the flare-bevel-groove weld??
If I were to use 2 symbols to ensure proper weld beads applied, would this ensure that the weld bead go all the way around the joint. There would be no gaps in the corners of the joints?
