Effect of laser-welding parameters on the heat input and weld-bead profile [PDF]
Journal of Materials Processing Technology, 2005 Laser butt-welding of medium carbon steel was investigated using CW 1.5 kW CO2 laser. The effect of laser power (1.2 - 1.43 kW), welding speed (30 - 70 cm/min) and focal point position (-2.5 - 0 mm) on the heat input and the weld-bead geometry (i.e ...
