Welding Symbols

[Ramadan Ahmed]

Good evening all,

I'm working on a design which is a 2.5mm Aluminum that is bent in various location to form a box. i want to use welding symbols (I'm new to welding symbols) in Sledworks, but I'm not sure which symbol to use in these areas shown. can someone help me with this please

Thank You

By inspection I think those tight bends will cause cracking depending on the material and the orientation .
Transverse direction is more vulnerable to cracking in rolled plate.

The loading in service will determine if fatigue failure is a consideration, and that can have profound effects on the weld design and weld process required.

AWS A2.4 shows most of the possible weld configurations and the symbols that define them.

Some more technical details would help others provide useful answers.
I wonder if you have the details you need.

In my experience, welders don't really like being told how to weld anyway so I wouldn't get too caught up in the symbols. I would just use a note pointing to it to the effect of make sure this gets welded, and any notes about bead size needing to be minimal or grind flush if mating up with another part is a concern.

I would start with a fillet weld symbol so that the welders can have a starting point - they won't know what they want until you tell them, then they will tell you they don't want that.

I agree with the observation that the apparent bend radii are too small; most aluminum alloys have a minimum bend radius of 2-5 times the material thickness. Maybe 1000 series can be bent that tightly, but it has the same strength as aluminum foil.

Overall it may be far better to do more welding with simpler transitions than to try to form and make match all these joints.

Some of the bends look like compound curves. Is this part stamped or formed on a press brake?
