Analysis of Beam Material Interaction in Welding of Titanium with Fiber Lasers

Ytterbium fiber laser welding of Ti6Al4V alloy

“…When it comes to the fiber laser, the good beam quality coupled with high CW powers offers deep penetration welding as well shallow conduction mode welding. These lasers can be used in a diversity of materials as the low wavelength allows absorption by almost all metals and alloys [11]. As demonstrated by Caiazzo et al, an appreciable improvement in seam quality was also achieved by adopting disk laser source [12].…”

“…Laser welding is one of the most suitable joining technique performing metal assemblies [11]. A wide range of intricate weld geometries and configurations can be produced with high levels of productivity, quality and flexibility.…”

Analysis of microstructure and mechanical properties change in laser welding of Ti6Al4V with a multiphysics prediction model

“…The recent high power fiber lasers offer several benefits compared to CO2 and Nd:YAG lasers, such as high power with low beam divergence, flexible beam delivery and low reflectivity as described by Costa et al (2007). The low reflection of a fiber laser beam enables the laser welding of diverse materials.…”

Fiber laser welding of NiTi to Ti-6Al-4V

“…Since NiTi also exhibits characteristics of biocompatibility, joining to Ti alloys would be of major interest for biomedical applications, especially the most common one Ti-6Al-4V [13]. However, they have different thermo-physical properties leading to different heat transfer rates in each material.…”
