"We just got this Inconel alloy plate in......its worth $20,000....you have 3/8's margin for mistake....don't screw up
plasma cut takes an 1/8th....not much room left....lots of nail biting and prayer : )"
The inverse of plasm cutting; emersion arc welding.
You got to lay the track before you do the tack.
My ex FIL welded six inch plate most of his life.
I'll take a burn from welding over a lance rod thru 8" steel.
blow back slag is unforgiving : )
Had a Pigeon land in the gantry tank and swim around while cut was occuring.
Must have been a Bronx Pigeon : )
