Laser welding/brazing of 5182 aluminium alloy to ZEK100 magnesium alloy using a nickel interlayer
Source abstract
Abstract
Aluminium alloy and magnesium alloy were successfully joined by using laser welding/brazing technology via a nickel interlayer. Microstructure and mechanical properties of the dissimilar Al/Mg joints with and without a nickel interlayer were comparatively investigated. No joints were achieved without a nickel interlayer; after welding, specimens were separated without applying any force. By inserting a nickel interlayer, sound metallurgical bonding were obtained at the interfaces. Hence, the joint strength reached 410 N with the failure at Mg/Ni interface. The influence of Ni interlayer on the weld defect, microstructure and joint strength was studied, and the joint formation mechanism was also discussed.
