Dissimilar Welding Of A7075-T651 and AZ31B Alloys by Gas Metal Arc Plug Welding Method

Innovative welding techniques allow for the fabrication of light, high-specific-strength, and fuelsaving Al and Mg alloys for use in transportation industries. Furthermore, these techniques have minimal detrimental impact on the environment. However, the poor mechanical properties of joints resultin...
