Siab - zaus vuam pib hauv xyoo 1950. Nws siv cov nyhuv ntawm daim tawv nqaij thiab cov nyhuv sib thooj uas tsim los ntawm siab - zaus tam sim no rau vuam steel phaj thiab lwm yam ntaub ntawv hlau. Ib tug tshiab welding technology rau pob tw welding ntawm cov ntaub ntawv. Qhov tshwm sim thiab kev loj hlob ntawm siab - zaus vuam tshuab tau ncaj qha mus rau txoj kev loj hlob ntawm txoj kev ncaj welded yeeb nkab kev lag luam, uas yog ncaj qha txheej txheem ntawm seam welded yeeb nkab (ERW) ntau lawm. Qhov zoo ntawm - zaus vuam ncaj qha cuam tshuam rau tag nrho lub zog, qib zoo thiab kev noj qab haus huv ntawm welded yeeb nkab khoom, ntau lawm ceev.
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.
Ua ntej, nws yog lub hauv paus ntsiab lus ntawm high zaus vuam.
"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.
Qhov thib ob yog cov qauv thiab kev ua haujlwm ntawm cov khoom siv vuam ntau zaus.
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.
