Hi all,
I am rather new to this site, having problem with a pin size hole near bottom of my 98 shadow gas tank. I tried jb weld stick as well normal jb weld paste with no success. Some one suggested under water welding or submerge welding but I have no clue where to get that kind of service. The tank is off my bike now and the leaking area is cleaned off free from paint and debris. Please help, I would really like to be able to cruise this coming weekend.
Any comments and/or advices will be appreciated.
Thanks all in advance.
 
mig welder will do if its a steel tank otherwise tig (believe its steel). The welding will ignite the vapours in the tank if there are any so...drain it and make sure its cleaned out WELL before trying to weld it.
 
Thanks skip, I tried to empty the tank but there seems to be some some fuel still left, I am not sure how to get that last once out. If you meant the welding area is cleaned, yes it is, maybe too clean the jb weld slips right off after a while :). I am tempted to drop a few drop of solder in there but not sure if it will stick.
 
Rinse the inside out and let it dry in a sunny spot. The problem with welding a gas tank is gas burns but gas vapours explode. You don't want any gas vapours left in the tank when you try and weld it or the heat/spark will set them off. That was why you friend suggested underwater welding.
 
If they are pinholes, they can be plugged with plumber's epoxy putty available from the plumbing section of any hardware store. It is a two part epoxy putty that is kneeded together. It is like playdooh when mixed but hardens to a rock in 5 or so minutes. It is impervious to gas. I have fixed tanks with this several times and one is going on 7 years now with no failure. If the holes are bigger, it would be best to have them professionally welded. As noted welding a gas tank is very dangerous so take it to a pro.
 
Brazing is the right way to do it.
 
I would use an old school soldering iron like this . No Flame ..Just a lb of copper you preheat with a torch, or in the old days , a charcoal burner.

It is close to impossible to wash al lof the gas out without some sort of hot tanking process, the metal absorbs gas ands will release vapours for month. Ì have heard of filling tanks with inert gas such as nitrogen, argon, or maybe CO2 to weld them..
