Here's another trick. When I added a float switch to my hot water tank to interlock the heter element, the tank had already been used many times for biodiesel. I evacuated all the air from the tank and then backfilled it with inert gas before welding. If you have a MIG welder and you have inert gas it is easy to do this.
