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.
