The working process of automatic spot welding machine is described in detail

The process of the automatic spot welding machine is to register cooling water, clean the surface of the welding part, the device is accurate, and put the upper and lower electrodes, apply pressure, so that the contact is prominent; The charging causes the contact surface of the two workpieces to heat up and partially melt, forming a frit. Keep the pressure after power off, so that the frit cools under pressure and condenses the structural solder joint; Pressure relief, take out the workpiece, the visual soldering system is the core element of the visual soldering machine,

Preparation and installation of welds: Before welding steel welds, it is necessary to remove all dirt, oil, oxide and rust, automatic dispensing machine is widely used in semiconductor, electronic parts, LCD manufacturing and other fields, for hot-rolled steel, it is recommended to use pickling, sandblasting or grinding wheel to remove the oxide at the weld. Although the uncleaned welds can be spot-welded automatically, the service life of the electrodes is severely reduced.

There is also a decline in the production of different power and quality of fully automatic spot welders. On the thin coating of low and medium structure carbon steel materials can be directly welded, in the welding process of low carbon steel, automatic spot welding machine can use strong standard welding method (instantaneous system power) or weak standard welding method (long-term power). Strong standard welding method should be used in the production of a large number of enterprises.

It can improve production efficiency, reduce power consumption, and reduce workpiece deformation. The welding current depends on the size, thickness and contact surface of the weldment. In general, the higher the metal conductivity, the greater the electrode pressure, and the shorter the welding time should be. The required current density increases.
