Warren,,,did you use a explosion meter first,,a sniffer,,or did you just do it and weld on the pressure vessel...There is a guy down here that wants to o some welding on two big propane tanks and I'm a bit nervous,,,I had figured on flooding them with Co2 first...
The steel must be cleaned with a de-greasing type
cleaner, but it welds perfectly once surface cleaned.
I can attest to this from personal experience. The
other thing I can attest to is the smell of an old
and heavily used propane tank once you cut into it!
Wow! There is nothing as potent!
