Electron-beam welding (EBW) is commonly employed in the aeroengine industry for the welding of high integrity components, fabricated from high-strength superalloys. For such applications, it is important to predict distortions and residual stresses induced by the process. Melt run trials have been c
## Abstract Sheets of AA6056 and Ti6Al4V were butt‐joined by inserting the Ti‐sheet into the profiled Al‐sheet and by melting the Al‐alloy alone using a split beam Nd:YAG laser. To study microstructural effects on properties, the Al‐alloy was used in two tempers; T4 followed by post weld heat treat
