Explosion welding of titanium - copper bimetals

The paper deals with explosion welding of titanium and copper in order to produce bimetals suitable for making targets used in sputtering process. Paper describes materials frequently used for target fabrication and technologies often used for their production. There are also brief characteristics of welded materials, their mechanical and other properties as well as need for their purity. A key part of the paper is devoted to explosion welding process, its description, including welding parameters, used explosives and welding procedure itself. The last part of paper deals with quality control examination of final bimetal, i. e. ultrasonic testing, mechanical testing and microstructure analysis.
