Spot welding of magnesium alloy was a complex processes of thermal, electrical, mechanical and metallurgical mutual coupling, meanwhile its’ low melting point, high thermal conductivity, and high linear expansion coefficient increased the welding quality control difficultly. Basing on SYSWELD, a numerical simulation of effects of welding current, welding time, thickness of plate, electrode pressure gauge and size on the nugget shape and welding quality of ZA31B was demonstrated. The relationship between the size of the nugget dimensions and the welding parameters was established by a large number of simulation and experimental study. The experimental results showed that the analogue result was consistent with the test results, and it could be used to guide the actual production.

Planar Impact

The process of concrete under symmetric impact was experimentally investigated in the case of primary gas gun and was analyzed .The shock properties of C100 concrete is investigated by gas gun planar impact technique. The manganin pressure gauge is used to measure the pressure-time curves of the samples. The parameters of high-pressure equation are obtained by the numerical simulation. Numerical simulation is a necessary complement to the test. The spall phenomenon is observed by the numerical simulation.
