Industry welds on tanks all the time that have been used for explosive
and flammable materials. There are always prescribed cleaning procedures
carried out before it's done. Safe enough if the safety rules are
followed and performed by the pro's. But, I agree with you.. If new
tanks are available, why bother with all the cost of steam cleaning,
purging, steam cleaning, and purging again on a used Vanagon tank. Get a
new one and get it right the first time. Tanks are not that expensive,
relatively speaking.
