Welding pressure is one of the main welding parameters of the intermediate frequency spot welding machine, which perfectly controls the welding current, welding time, and the product welding performance and actual welding effect of the intermediate frequency spot welding machine.
The relationship between the welding effect of intermediate frequency spot welding machine and welding pressure:
The welding pressure of the intermediate frequency spot welding machine is supplied by the cylinder: directly applied to the surface of the product through the electrode head, making the product workpiece in close contact.
The pressure between two workpieces and the electrode during welding greatly affects the welding quality of the product. When the upper and lower electrodes are squeezed, the current passes through the workpiece, melting the metal plate and forming a solder joint.
It is generally believed that the welding pressure required for thin plate welding is small, while the welding pressure required for thick plate welding is large. The opposite is true in practical applications. The pressure during frequent welding of metal sheets is slightly higher than usual.
In this way, when the board melts, it can immediately and effectively overcome the deformation of the wood, and the back welding is well formed, known as seamless spot welding. When welding thick plates, the pressure does not need to be too high. It should be slightly smaller than usual. The deformation of the back no longer depends on pressure, as the pressure is small and the spatter is small, resulting in good formation of the weld nuggets
