I understand that a weld, if done properly, is stronger than the base metal. Does this mean that if you have a part that needs to be formed, the bend can be made along the weld? Or is the weld filler more brittle or have some other material property that would prevent this?
As an example, I have the part in the image below. It is to be formed with bend lines at the green dashed lines. Due to manufacturing limitations, I cannot form the entire part at once, so I have to split it, form it and re-weld it. I can split it anywhere along the length of the part. But, out of curiosity, I'm wondering if I can make a vertical cut on one of the green dashed lines (indicating a bend line), form the parts separately, weld them back together, and make the final bend along the weld joint.
The welding process is TIG. The base metal is 1100 Al, which is welded on both sides with 1100 Al filler.
