Compared to aluminum and steel manufacturers, high thermal conductivity of aluminum, welding, requires a high heat input. When welding large cross section needs to be preheated. When using resistance welding, and weld steel compared to aluminum prices, because aluminum has a high electrical conductivity, so they need a larger current and short welding time to accurately control the welding parameters. Because aluminum is not magnetic, when welding aluminum with a DC arc will not blown migraine. Therefore, it can be used as welding apron and fixtures. 6 *** series aluminum tube profiles and corrosion resistance of aluminum welding performance 6 *** series features: magnesium and silicon based. Mg2Si as the main strengthening phase, currently the most widely used alloys. 6063,6061 with most other 6082,6160,6125,6262,6060,6005,6463. 6063,6060,6463 in 6 lines of relatively low intensity. 6262,6005,6082,6061 6 lines relatively high intensity.
