Abstract

The purpose of this study was to develop the remote laser welding technique for galvannealed steel sheets using the pre-deforming process by laser heating and to develop in-line inspection system for remote laser welding system using visible images. It was concluded that the weldabillity of lap welding joint of galvannealed steel sheets could be improved by making the sheet gap of more than 0.04mm using the laser pre-deforming process before laser welding and moreover the quality of lap joints could be evaluated by using the proposed in-situ monitoring system.
