:welderI've noticed a leak in my landrover's fuel tank lately and decided to pull it out for repair. On observing the leak it seems that fuel is coming out of a cracked side seam, most probably due to off road use, and not due to rust...Which welding process do you recommend; mig is obviously good but i am afraid it can perforate the sheet or not seal it correctly. Brazing using oxy fuel might be a good choice however I am not sure it will hold the pressure and offroad abuse.
