Stainless Bob tack welding our solar arch on deck of our boat in Brighton in 2016. The only part of the refit I didn't do myself.
I thought he was doing a pretty good job of this. I later found out he's got a stack of welding certifications, including one for work on nuclear power plants
He could weld stuff other welders called impossible, like a new exhaust pipe into the rotten aluminium body of a diesel heater.
