It is indeed TIG welding. You strike an arc between two tungsten
electrodes, shielded by an inert gas. Hence, Tungsten Inert Gas welding.
3) Thoughts on repairing the chassis? I could
bondo, superglue, epoxy,
silversolder, etc. the pieces together, and add a plate behind it
attached with countersunk screws. Would not be very visible once the
panels are put back. I have the two side panels and the bottom panel,
but no top panel. Thoughts on which would work best?
I think your best bet is welding. I believe that welding aluminum
requires special equipment. A guy at my office does something called
TIG welding for his robotics projects. I think the weld can be sunk
into the material and ground smooth afterwards, giving a nice
appearance. It will probably be expensive to have this done, however.
Not sure about cost.
In all welding, the weld should penetrate right through the metal,
otherwise it's just a snottery blob on top that won't hold anything. It
should be possible to grind the weld flush without weakening it.
