| Research Abstract |
Laser spot micro joining method between plastic and metallic materials applying for welding of micro parts was studied. In order to improve intrinsic joining strength, effects of molten pool shape formed in a metallic material side, bubbles formed inside a plastic material nearby the interface and applying static and cyclic contact force were investigated. Appropriate condition of the molten pool shape and state of the bubbles formation were shown. Moreover, controlling method of formation behavior of the bubbles was developed. A new dissimilar materials joining method by optimizing in mechanics and process was proposed.
