It should be noted that the heating principle herein can refer to the high-frequency welding principle. The high frequency is a high frequency current of 50KHz to 400KHz, which is generally referred to as an alternating current frequency of 50 Hz. When high-frequency current passes through a metal conductor, two peculiar effects, namely a skin effect and a proximity effect, are generated, and the high-frequency welding is used for welding steel pipes.

The skin effect is that when an alternating current with a certain frequency passes through the same conductor, the density of the current is not uniformly distributed on all the sections of the conductor, and the current is mainly concentrated towards the surface of the conductor, namely the current is high in density on the surface of the conductor and low in density inside the conductor, so that the skin effect is vividly called as the skin effect. The skin effect is typically measured by the penetration depth of the current, the smaller the penetration depth value, the more pronounced the skin effect. This penetration depth is proportional to the square root of the electrical resistivity of the conductor and inversely proportional to the square root of the frequency and permeability. In general, the higher the frequency, the more concentrated the current is on the surface of the steel sheet; the lower the frequency, the more dispersed the surface current. It must be noted that although steel is a conductor, its permeability decreases with increasing temperature, that is, as the temperature of the steel plate increases, the permeability decreases and the skin effect decreases.

The proximity effect refers to that when a high-frequency current flows in opposite directions in two adjacent conductors, the current flows intensively to the close edges of the two conductors, and even if the two conductors have a shorter side, the current does not flow along a shorter route, and the effect is called as the proximity effect. The proximity effect is essentially due to the effect of the inductive reactance, which plays a dominant role in high frequency currents. The proximity effect increases with increasing frequency and closer spacing of adjacent conductors, and if a magnetic core is added around the adjacent conductors, the high frequency current will be more concentrated in the surface layer of the workpiece.
