Joining Technology of Dissimilar Materials for Automotive Components (II)

摘要

Joining techniques of dissimilar materials for lightweight multi-material automotive body structure were discussed. The joining of 1.4 mm thickness steel and 2 mm thickness of Al were performed by the new method that is hybrid laser welding system. After aluminum and steel were welded by laser hybrid welding process, the micro-structure investment and the micro-hardness test were carried out. Hybrid laser welding promises a bright future in joining technology of dissimilar materials for automotive components.
