Factor 3: Weld Seam Arrangement In modern automotive body welding, laser welding has been widely adopted to replace traditional resistance spot welding. This shift aims to reduce costs, enhance production efficiency, significantly improve impact resistance and fatigue resistance of the vehicle body, and consequently elevate overall automobile quality. Laser welding, characterized by rapid energy release,…
Factor2: Overlap Joint Gap Between Two Panels During the stamping process of vehicle body components, springback deformation is prone to occur, resulting in a certain gap between the overlapping joints of the two components even under a specific clamping force. Due to the impact of zinc vaporization in galvanized steel plates used for the vehicle…
As a highly advanced welding technique, laser welding is generally preferred for application in parts where stringent welding quality is required. In such parts, if spot welding is chosen, the limited welding space would lead to intricate process arrangements, resulting in subpar welding quality and an inability to achieve the desired visual quality effects in…
The laser welding process for automotive body structures demands a high level of seam recognition and localization. Swift and accurate identification and positioning of seams are essential technical means to ensure an intelligent welding process. Seam tracking during the automotive body laser welding process relies on real-time sensing by sensors on the workpiece, determining seam…
