| Abstract Scope |
Additive Manufacturing (AM) has attracted a great interest to many industries, namely, aerospace, biomedical, and automotive. AM enable to produce intricate designs, economising manufacturing. However, AM methods are constrained to long build times and relatively small-size parts. One way around this is to print small components follow by welding.
The aim of this study was to analyse the weldability of additively manufactured Ti6Al4V and SS304. The coupons were manufactured using Selective Electron Beam Melting (SEBM) followed by welding using Gas Tungsten Arc Welding (GTAW). Microscopy examination revealed martensite structure in the fusion zone (FZ) of Ti6Al4V that increased its strength (hardness). Hardness of SS304 deceased at the fusion zone (FZ). Following tensile testing, it was revealed that fractured took place in the heat affected zone (HAZ) for Ti6Al4V and in the FZ for SS304, and both showed dimple fracture mechanism. |
