True. We use stubwelds in our oil drilling equipment, and it seems to work well, but it may simply be an operational requirement, as the diameter must remain the same.

The hardest part, I suspect, is lining up the two pieces perfectly, and would have to include cutting an angle into the edges to be joined, for the welding to take place.

I don't believe that it would be impossible on Alu 2 to 4 mm thick, but I've never done it, nor seen it done. I can however imagine that the process would be exactly the same, but would require a much smaller feed wire.

I don't believe that a socket weld would be desirable here.:shrug:
