Welding Aluminium Fuel Tank. Pure aly sheet was used with a pure aly filler rod for welding. Removed sending unit and pick up tubes.
Pure aly sheet was used with a pure aly filler rod for welding. An old welder I used to work with told me that he witnessed a man get his face peeled off while welding on a gas tank full of water so evidently thats not foolproof. A good purge is very important.
I removed all the fuel from the tank.
Diesel fuel will not explode like gasoline will. Purging with any inert gas used for welding will prevent combustion just be careful of pockets that could hold vapor. The material thickness was 2mm the trank was welded with open corner joints on about 80 amps. I removed all the fuel from the tank.
