Study of Weldability for Circularly Input Heat

Abstract:

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. Although laser welding, which yields low-distortion joints, was developed in response to this demand for high accuracy, it has been difficult to meet the needs of modern, high-accuracy automobile parts with conventional laser welding. In this research, in order to realize that degree of accuracy, a phenomenal and theoretical analysis of the melting solidification process was conducted and high-accuracy laser welding was investigated for controlling welding deformation.
