[Shop-talk] Welding a full tank

[crothfuss at coastalnet.com]

Eric,

   If this is a tank full of flamable liquids (like gasoline) it's a lot of work to drain/fill with water/drain water/dry/refill w/flamable liquid.  Far easier to just remove the oxygen needed to support 
combustion.  Car exhaust is available and portable.  With exhaust pumped into the container to purge the
oxygen, you can weld the tank quickly without all the problems water can create.  I've done this on several
gas tanks.  As always YMMV.  No idea if it's OSHA approved, or if it'll be safe on every kind of tank/flamable liquid.

Chuck
