The picture shows the aluminium skirt at the bottom of the box on a box truck. The metal is about 3/16 in thick and the gaps are about 1/16 in. Can this piece be (tig) welded back on? I can do stick and flux core but nothing more, so I will have to take the truck to a welding shop.
There are two vertical joints and one horizontal joint. The vertical joints are 5 ins long. There is nothing behind the cuts, it is empty space.

Is that area structural at all, or stressed ?
If not, there are aluminum rods that you can braze it with a propane torch.

There will be stress on it. A frame cross member of the truck box will be riveted on to the cut piece. When the truck box flexes over bumps there will be stress.

Call around to a welding shop and get a quote . Pro welders can make the weld strong and look cool.

I'm a UPS semi mechanic. We have a trailer shop. A box trailer has similar construction. That is an easy fix. A trailer shop might fix it for you cheaper than a welder/fabricator.

I could easily weld that with my TIG.


People who count on their fingers should maintain a discreet silence.
