In: Journal of Materials Processing Technology, pp. 2009-2017, 214, [Article]

Abstract

tDespite the great technological advantages of impact welding, its application is still not widely spread.One reason is the poor understanding of its mechanisms and the effects on the bond strength. In thispaper, a novel test rig is presented, which allows the straightforward investigation of impact weldingand its basic principles to help filling this gap of knowledge. Impact angle and velocity, which are knownto be the most important process parameters, can now be freely and almost independently varied overa large range of values. The built-up of the test rig and its functionality will be presented in this paper.Furthermore, first numerical and experimental results will be discussed and compared to an industriallyimplemented process. The investigations show that the test rig is capable of representing the high-speedcollision of the real process.
