  • Comparison of continuous and pulsed wave lasers in keyhole welding of stainless‑steel to aluminium 
    Coroado, Julio; Ganguly, Supriyo; Williams, Stewart; Suder, Wojciech; Meco, Sonia; Pardal, Goncalo (Springer, 2021-10-31)
    A continuous wave (CW) and a nanosecond pulsed wave (PW) lasers were used to join 1-mm thick sheets of SS304L (SS) austenitic stainless-steel to AA5251 (Al) aluminium alloy in an overlap joint configuration. The weld shape ...
  • New phenomenological model for comparison of lasers with different temporal outputs 
    Coroado, Julio; Williams, Stewart W.; Suder, Wojciech; Ganguly, Supriyo; Meco, Sonia; Pardal, Goncalo (Springer, 2022-04-06)
    Laser welding is distinguished by low heat input, low distortion, high travel speeds and accuracy. Traditional high-power pulsed wave (PW) lasers are being replaced by high-frequency low-pulse energy fibre lasers. However, ...
  • Selection of parameters in nanosecond pulsed wave laser micro-welding 
    Coroado, Julio; Ganguly, Supriyo; Suder, Wojciech; Williams, Stewart; Meco, Sonia; Pardal, Goncalo (Springer, 2021-05-31)
    The digital control of the latest nanosecond pulsed wave (PW) fibre lasers allows very high flexibility in controlling the application of the total energy to a workpiece, which brings several advantages to the joining ...
