Aluminum plate spot welding machine diagram
Aluminum is a chemically active metal.General resistorThe spot welding machine can only weld aluminum foil strips, and any thick ones must be used.Medium frequency spot welding machineCome and weld.It is easy to form an oxide film (Al) on its surface that prevents the metal from further interacting with the surrounding medium.2O3) In atmospheric media, it has high corrosion resistance. Such as H2S.SO.NH3Does not affect the corrosion resistance of aluminum at room temperature. Steam, distilled water, and pure fresh water have no effect on the corrosion resistance of aluminum at high temperatures. Therefore, aluminum has better corrosion resistance than copper under these conditions, which is an advantage for the use of aluminum instead of copper. But the melting point of Al2O is very high, 2050°C, which is more than three times the melting point of aluminum, 658°C. It is also much higher than the melting point of copper, 1083°C. From the above points alone, it is difficult for people to perform spot welding.
