Abstract
A method of making a gas tank includes hydroforming two halves and welding the halves together. Two types of welds are used in welding the two halves together, tack welds for holding the two halves together, and stitch welds to complete the welding of the two halves. Additional steps are taken prior to the finishing stitch welds. Reinforcement is added where necessary. Double tanks, for both gasoline and oil, are also fabricated by essentially the same method steps.
