Tig or mig ?

[Olav]

I have cut and opened the tank. Have cleaned and opened and welded several tanks earlier.( We have a"gas analyzer" for use in ship/ tanks.) My earlier problems regarding leaks have I sorted out. Some of the problem was the galvanizing inside and outside the tank.
And some issues I don't want to tell you about :-/

There was not a big leak last time but I want to do a good job as possible and it must be looking good also.

If you've already cut open the tank, then you should be good to go.

Just make sure you leak test it with something that isn't flammable before actually putting gasoline in it. Water works.

There was a nice thread on this not too long ago. You might want to do a search.
