Electron katako waldi - fasahar siffofin

A cikin high-tech shekaru zama more kowa tsaurin, zafi-resistant, lalata resistant da kuma radiation-kayan for waldi wanda bukatar da dabaru na musamman. Kamar electron katako waldi, a cikin abin da aiki aiki zone zazzabi ya kai dubu sau ya fi girma index fiye da na al'ada hanyoyin. Ultrahigh zafin jiki a irin wannan waldi aka samu saboda da photons ko electrons motsi a cikin wani injin jam'iyya a gudun game da 165 000 km / sec. Lokacin da karfe aka bombarded a wata m gudun sanadin motsi makamashi na firamare barbashi ne tuba zuwa cikin zafi, wanda ya narke karfe.

Electron katako waldi aka yi a wani na musamman jam'iyya, daga abin da pre-kwashe. Injin da aka halitta saboda haka cewa electrons ba ciyar da kuzari da ionization na gas cakuda kuma su sami cikakken welds ba tare da kasashen waje karfe inclusions. Electron katako da kafuwa, wannan ne ake kira a injin jam'iyya sanye take da wani musamman Magnetic ruwan tabarau, domin kafa wani umarni kwarara daga electrons, da kuma tasiri management. Har ila yau ya samar da welded sassa shi ne ba caji tashar jiragen ruwa.

Electron katako waldi aka sanya low irin ƙarfin lantarki alternating halin yanzu. Yana gudana ta hanyar musamman Yana zuwa kashi (ruwan tabarau), inda cathode ga anode, kuma ta haka ne, da electron katako da aka halitta da so halaye. A cikin low-ikon shigarwa an yi amfani da matsayin cathode Helix na tungsten, ko Tantalite. Idan aiwatar da mutum Properties na welded kayan na bukatar karin iko, alhãli kuwa riga amfani cathodes sanya na cermet ko lanthanum hexaboride da ciwon wani ƙara ikon da watsi da free electrons.

Dangane da tsarin fasali na kafuwa, electron katako waldi iya yi da motsi da kayan da za a welded perpendicularly ga ajali katako ko mataimakin versa katako iya matsar da dangi zuwa ga ajali part. Har ila yau, wasu shuka zane azurta musamman deflectors, wanda ya ba more damar da za ka samu dimbin yawa seams.

Wannan irin waldi ne yadu amfani a waldi na high gami steels da titanium-tushen gami kazalika da karafa kamar molybdenum, Tantalite, niobium, tungsten, zirconium, beryllium. Lokacin da cikakken aiki da waldi na daban-daban mikrodetaley. Ana amfani da a masana'antu kamar roka kimiyya, makamashin nukiliya, daidaici kida, microelectronics da yawa wasu.

Bugu da kari ga electron-katako fasahar ne tartsatsi, kuma Laser waldi. A kayan aiki ga irin wannan waldi - Tantancewar Laser oscillator, wanda shi ne wani matsananci tushen jiwuwa radiation. A manufa na Laser waldi Ba kamar cathode-ray Hanyar shi ne cewa shi ba ya bukatar injin bẽnãye ga shi. Welding aiwatar da Laser fasaha yi a cikin iska ko a cikin wani masallaci a karkashin yanayi na jikewa da musamman m gas - carbon dioxide, argon da helium.
