ã€China Aluminum Network】 When the workpiece and the electrode are fixed, the resistance of the spot welding workpiece of the aluminum basket basket welding machine depends on its resistivity. Therefore, the resistivity is an important property of the welded material. The metal with high resistivity is conductive. Poor (such as stainless steel) metal with low resistivity has good conductivity (such as aluminum alloy). Therefore, aluminum basket basket welding machine welding spot welding stainless steel heat production is easy and difficult to heat, aluminum basket basket welding machine welding spot welding alloy heat is difficult and easy heat dissipation. Spot welding, the former can use less current (a few thousand ampere ), while the latter must use a very large current (tens of thousands of amps). The resistivity depends not only on the type of metal, but also on the state of heat treatment, processing method, and temperature of the metal. In order to ensure the size of the nugget and the strength of the solder joint, the welding time and the welding current can complement each other within a certain range. In order to obtain a certain strength of the solder joints, large currents and short durations (strong conditions, also called hard specifications) can be used, as well as small currents and long periods (weak conditions, also called soft specifications). The choice of hard or soft specifications depends on the properties of the metal, the thickness, and the power of the aluminum basket basket welder. There is an upper limit and a lower limit for the current and time required for metals of different properties and thicknesses, whichever is applicable.
