Laser welding can make very precise joints in plastics products, both in terms of joint location and amount of heating applied. (W 8) (1)

Laser welding = Soldadura a laser

Friction stir welding (FSW) is a joining process for metals that was invented in 1991 by Wayne Thomas at TWI. (W 35) (2)

FSW = Soldadura por fricção

In a recent project at TWI for the Ministry of Defence (MOD) to investigate the suitability of hybrid laser arc welding for ship construction, [3] the fatigue performance of these joints were of primary concern. (W 197) (3)
