The principle of high frequency welding machine to produce H-beam

Now with the upgrading of the manufacturing industry, the high-frequency welding machine has also entered a new stage. It is an indispensable environmental protection and energy-saving heating equipment in various industries.

The basic element of high-frequency welding H-beam production is high-frequency current, and the key to welding the H-beam into an H shape is: the adjacent effect and the skin effect caused by the high-frequency current. The following editor will introduce the principle of H-beam production by high-frequency welding machine. The content is as follows:

The skin effect is also called the skin effect, which means that there are many high-frequency currents with the same frequency. During the process of flowing in the same conductor, these currents will not have a lot of residues inside the conductor, and Most of the concentration is on the surface of the conductor, which leads to the appearance that the inner density of the conductor is smaller than the surface density of the conductor. Simply put, the skin effect is that when an alternating current passes through a conductor, the current will concentrate on the surface of the conductor and flow.

The proximity effect refers to the fact that when two conductors are very close together, and a high-frequency current is applied to the two conductors, the current will gather at the adjacent edges of the two conductors, which is also fixed. If there is a closer path between the 2 conductors, the place where the current collects also doesn't change.
