轻金属焊接学术前沿及其研究领域

Light metals such as aluminum, titanium and magnesium have become more and more important structure materials with their advantiges in material usege efficiacy, lightening weight and reducing manufacturing cost. The developments and possible research directons on welding technologies for light metals are summarized based on the Forum on Key Basic Research on Welding Technologies for Light Metals supported by the National Natural Science Foundation of China (NSFC). Four frontier fields are concluded according to the presentations and discussions of about thirty participents in the forum, i.e. the mechanical behaviors, the reliability and safety asseccment of light metal welded joint and structure, welding mechanism and technologies, and modeling and simulation of welding peocess and properties.
