Journal of Manufacturing and Materials Processing, 2023 The Friction Stir Welding (FSW) process depends entirely upon mechanical contact between the tool and the workpiece. As a result of this, all process phenomena and process outcomes such as weld geometry and mechanical properties are governed by FSW’s ...

Study of Weldability for Circularly Input Heat
Materials Science Forum, 2008 Different techniques are being studied to make the automotive electrical parts more compact and lightweight; along with improving their functionality for saving energy and protecting the environment. In the wake of this trend, the joints in these parts are required to have little distortion and a high degree of accuracy.

Effect of laser-welding parameters on the heat input and weld-bead profile [PDF]
, 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 ...
