Edge Weld Sheet Metal
Edge Weld Sheet Metal
(OP)
so I have made a box about 7inches tall. The other dimensions are not important for my question . The sheet metal is 1.2mm thick. I want a nice clean outer edge. The metal is SECC, electrogalvanized chassis steel, which would be painted after to be black. Can I just fillet weld the edges and then grind it smooth???

You can get a better joint if you use the " close joint" feature of your sheet metal Cad program. Solidworks and Geomagic have this feature, I do not know about other Cad programs.
Ideally the inside edges of the joint should just touch when the part is folded up.
B.E.
You are judged not by what you know, but by what you can do.

It is imaginary. Not fabricated.
Allow a full length tab about 1/2 inch (12 - 15 mm) long alone the the entire edge.
Fold up that tab to a 90 deg bend.
Fold up the bottom plate of the box to form the side (wall) of the box.
Weld the tab over the outside of the box (if the interior is to be smooth), or the inside (if the exterior corner is to be smooth), and weld it with a compression welder (spot welder) 3 - 6 times.
