Abstract
Abstract Linear Friction Welding (LFW) is a rarely used joining technology. To test the suitability of this solid-state process for hot cracking-sensitive nickel base superalloys, tests were performed using conventionally and directionally cast slabs of Alloy 247. Since LFW does not involve melting of the weld flanks, there were some expectations that this special welding technique could overcome the poor weldability of Alloy 247. However, all tested specimens failed by liquation cracking (LC) within the Weld Center Zone (WCZ) at the directionally cast side.
