Abstract
Feasibility to use the high-speed liquid impact for joining similar and dissimilar metals was investigated experimentally. An experimental setup that entails a launcher for projectiles formation and samples folders was constructed. The experiments involved joining of sandwiches containing two or three layers of metals were impacted by a high-speed projectile. The metals combinations included copper, brass, steel, and nickel alloys. The generated samples were examined visually, the strength of the joint was explored, and the integrity of the weld was estimated using ultrasound. In most of the experiments metallurgical bonding of joined metals was confirmed. The results of the ultrasound test demonstrated high quality of the generated joints. The performed experiments showed feasibility of the liquid impact-based welding. This process is the improvement of the explosion welding. Unlike the explosion welding impact-based process does not require special placing of work pieces while the stresses in the impact zone can be precisely directed and controlled.
