Against the manufacturing requirement for both lower lead time and reduced machining time for titanium components, a new concept was conceived assembling sheet material and other stock into semi finished parts by (explosive) impact welding. It is believed that this concept (which we named SLAM) could be especially beneficial for titanium alloy and nickel alloy.The present investigation centered on the feasibility of this technology for the widely used Ti6Al4V alloy.Impact process parameters were established and mechanical properties were investigated. In general, static properties were good. Fatigue strength reduced however, although much less so for notched specimens compared to un-notched material.Fatigue crack initiation could be linked to complex features within the (wavy) weld interface associated with the ‘first generation’ impact welding parameters. Next steps are foreseen to improve the fatigue performance.Two manufacturing demonstrators were manufactured showing the application to a T-bar manufactured from plate and sheet, as well as a tool-cladding application.
