For this work, because of the former requirement, the need for an efficient, robust and compact laser source and the need, in remote applications, for optical fibre delivery of the laser beam power, a 5kW multimode industrial fibre laser was chosen. (W 83) (1)

Fibre laser = Laser de fibra

Based on the findings, autogenous laser and hybridlaser-MIG welding trials were performed to establish the minimum and maximum welding speeds for full penetration, with subsequent trials assessing the influence of alloy composition, surface oxide, laser spot size, welding speed and welding process…(W 172) (2)

Autogenous laser = Laser autógeno

The purchase and running costs of near infra-red (NIR) lasers, particularly diode lasers, have fallen over recent years. This, together with innovations in equipment, materials and processes, has opened up a wide range of applications to through-transmission laser welding. (W 243) (3)
