I have a 20 year old diesel tank that has a small leak at or near a
bottom weld.

I've been thinking of taking it to a heliarc welder to attempt a
repair.

Comments?

gas explodes,if a tank is filled with liquid even desiel it will not
explode but the heat loss when welding can be a problem one solution
is to fill the tank with soap bubbles useig a soapy liquid and an air
line then weld a large patch on the bottom of the tank.
