试验表明,用改进型的GMAW工艺焊接钢和铝,有好的抗拉强度、耐腐 蚀性以及极限疲劳强度。 铝与钢焊接能改善工业领域内零件的特性。尤其是汽车行业,这两种 金属的结合通过减轻重量,使耗费的能量最少。 直到最近,这两种金属零件的机械连接仍为压接,螺纹连接,等,大多数 用于零件间的系牢或折弯绑扎。由于加热后金属间相的变形,而且这些相 Experiments show that, with the improved GMAW welding process of steel and aluminum, have good tensile strength, corrosion resistance and ultimate fatigue strength. Aluminum and steel welding can improve the characteristics of the parts in the industrial field. Especially in the automotive industry, the combination of these two metals minimizes energy consumption by reducing weight. Until recently, the mechanical connection between the two metal parts was still crimp, threaded, etc., most of which were used for fastening or bending between parts. Due to the deformation of the intermetallic phase after heating, and these phases
