Visoko{0}}varjenje je nastalo v petdesetih letih prejšnjega stoletja. Za varjenje jeklenih plošč in drugih kovinskih materialov uporablja učinek kože in učinek bližine, ki ga povzroča visoko{2}}tok. Nova tehnologija varjenja za čelno varjenje materialov. Pojav in zrelost visoko{3}}tehnologije visokofrekvenčnega varjenja sta neposredno spodbudila velik razvoj industrije ravnih varjenih cevi, ki je ravna ključnega procesa proizvodnje šivnih varjenih cevi (ERW). Kakovost visoko{4}}varjenja neposredno vpliva na splošno trdnost, kakovost in zdravje varjenih cevnih izdelkov, hitrost proizvodnje.
As a welded pipe manufacturer, we must have a deep understanding of the basic principles of high frequency welding. Understand the structure and working principle of high frequency welding equipment; watch from a height or distance Key points of high frequency welding quality control. Here's an introduction for you.
Prvič, to je osnovno načelo visokofrekvenčnega varjenja.
"High frequency" refers to the frequency of AC current of 50Hz, and generally refers to the high frequency current of 50 kHz to 400 kHz. High frequency electricity When flowing through a metal conductor, there will be two peculiar effects: skin effect and proximity effect, which are used in high frequency welding. Welded steel pipe.
Drugi je struktura in načelo delovanja visokofrekvenčne varilne opreme.
To understand the principle of high frequency welding, it is necessary to have the necessary technical means to realize it. High frequency welding equipment is used to realize high frequency welding. Electrical-mechanical system, high-frequency welding equipment is composed of high-frequency welding machine and welded pipe forming machine.Wherein the high-frequency welding machine is generally composed of a high-frequency generator And its function is to generate high-frequency current and control it. The molding machine consists of an extrusion roller frame, and its function is to make the material to be extruded. The part melted by high-frequency current is extruded to remove the oxide layer and impurities on the surface of the steel plate, so that the steel plate is completely fused into one.
The above is the working principle of ERW tube mill.
