Zn-Cd钎料对6061铝合金与AZ31B镁合金钎焊性能研究

In this paper, the use of Zn-Cd solder thickness at different temperatures and soldering and brazing research on the performance of AZ31B 6061. The results show that: under the same welding temperature, 200 μm of the solder joints is larger than 100 μm in the solder after soldering solder joint shear strength; When the effects of brazing temperature on brazed joints largest brazing temperature using 390 ℃, the phenomenon appears incomplete welding, brazing temperature when using 420 ℃, will the craters, cracks and weld defects such as over-burning; Using 200 μm and the microstructure and mechanical properties of the weld obtained 410 ℃ is the best.
