摘要
The present invention relates to a method of manufacturing a fuel tank for a projectile using friction stir welding which improves corrosion resistance for a joint portion, reduces a fraction defective of the joint portion, and minimizes bending of the joint portion when welding to reduce the asymmetry of the tank. The method includes: a step of manufacturing a cylindrical body having a first length (L) and a diameter (D), and end covers corresponding to the upper and lower ends of the cylindrical body; and a step of carrying out friction stir welding on the cylindrical body and the end covers.;COPYRIGHT KIPO 2015
