Impact wave process modeling and optimization in high energy rate explosive welding

摘要: Impact waves are used in many different industries and classified according to whether they cause plastic or elastic deformations. In the deformation mode, these can be produce special electrical joints. detect leakage measure thickness of pipes. Both modes have applications offshore technology. this thesis application impact mode explosive welding discussed. (EXW) process a high velocity oblique produced by carefully controlled explosion occurs between two more metals. The causes metals behave like fluids temporarily weld together. This short time with rate energy. EXW is well known method for joining It multidisciplinary research area covers wide range science technology areas including wave theory, fluid dynamics, materials science, manufacturing modeling. Many important results obtained from experimentation. mainly based on experimental work. However, it begins review fundamental theory mechanisms steps successful operation. tests done horizontal vertical surfaces unequal surface areas, curved remainder evaluates experiments, measures main parameters, shows simulations verify results. ends number suggestions improving optimizing process. One improvements model metallic plates areas. An Al-Cu joint ALMAHDI aluminum factory, large company southern Iran that produces than 200,000 tons per year. Improved methods also suggested surfaces. These may extensive pipelines oil gas industries, especially underwater
