To weld the tank you need to degas it, there are 2 ways to do this
1; take it to a professional, should cost around $100 for a motorbike, more for a car.
2; get a length of flexible tubing that fits over the tailpipe of your car (diesel is best, but any modern standard car with injection is ok, needs to have neutral emmissions, not rich like most modified cars) and stuff it over the tailpipe of the car and into the emptied fuel tank. Start the car and let it idle for 1/2hr, the warmed burnt gases from the exhaust of the car will evaporate any fuel left in the tank and the associated vapours. You can also use nitrogen gas (or any inert gas for that matter) but as they aren't warmed it takes alot longer and costs $$$. Check the tank for gas, I do this by smell after it has sat for a further 1/2 hour. It should smell of exhaust gas and not raw fuel, it may be necessary to repeat the proceedure.
Weld the tank as required but ensure it has a decent vent to atmosphere ie the cap is removed.
Piece of cake really (btw if it all turns pear shaped, I never wrote this and will deny all knowledge of the proceedure) I've done 5-6 tanks like this now. I've had a couple of queries from various people so hope this helps
