Kuvele electrode njengoba aluminium. Izici yenqubo Welding

Aluminium uye iyomiswa iqine ekuphileni kobuntu. Minyaka yonke, ukusetshenziswa kwalo liyakhuphuka. Ngo umkhakha nabezindlu, kukhona imikhiqizo eminingi yale metal. Ukuze udale lezinto ezintsha noma silungisa ubudala izinjongo ezihlukahlukene yi electrode aluminium esetshenziswayo Welding. Indlela esetshenziswa ngayo, kufanele uqonde phambi ukusebenza.

I izakhiwo aluminiyamu

Ukuze uqonde ukuthi ukusebenzisa electrode for the Welding aluminium, kufanele kuqondwe ukuthi izinga esingokwemvelo we metal.

Ingaphezulu aluminium ngesikhathi namachibi emoyeni embozwe i ifilimu oxide. Kunzima ancibilike. Futhi-aluminiyamu Welding electrode Kuyothi endaweni ethile gaseous. Kungenjalo, amaconsi oncibilikisiwe lomcebo emoyeni ngeke oxidize futhi ngeke uhlangane ku into eyodwa. I umphetho ngaleyo ndlela ukudala engasebenzi.

Ukuze aluminium Welding a electrode tungsten isetshenziswa kabanzi argon ezibizayo noma ingxube yawo ne-helium.

Nakuba aluminium metal Incibilikile ngokushesha kunensimbi, edingekayo ukucubungula izikhathi 1.2 wamanje Welding.

Isimiso Welding electrode

Ukuze uqonde ukuthi yenza aluminium electrode, kubalulekile ukuba yokuqonda lokho okushiwo yinkulumo inqubo. Kunezinhlobo ezimbili eziyinhloko ngakho. Eyokuqala iqasha tungsten Welding electrode ekusebenziseni uma usebenzisa amagesi inert. Wabiza AC TIG.

Eyesibili indlela ukusetshenziswa electrode camera ngaphandle encibilika ukusetshenziswa amagesi inert.

Kuzo zombili lezi zimo, isimiso esejwayelekile ukuncibilika izenzo kudingeka ifilimu oxide. Ngenxa yale njongo i kushintshana noma ngqo wamanje polarity reverse. Lokhu kuholela cathodic disbondment ifilimu. Olunye uhlobo electrode samanje aluminium ngeke bakwazi ukugcwalisa umsebenzi walo.

Welding nge electrode camera

Zokushisela metal ezakhiwe nge ukushuba 4 mm ucezu kwenzeka ngokusebenzisa electrode camera. Le modi ubizwa ngokuthi MMA.

uhlobo enjalo zokushisela inika ukhwaliti ongaphakeme we weld, a afafaze ngokwanele ezinkulu nokususwa abampofu amanyela eqina. Kugcine kuphakamisa kumiswa ukugqwala.

I electrode ngokuvumelana yesimanje aluminium weld emamaki ivumela kakhulu zonke Alloys aluminium. Inqubo yenzeka esebenzisa zamanje ngqo kokuba polarity reverse.

Ukuze ikhwalithi umphetho kwaba kuleli uhla evamile, kumelwe kuqala afeze gaphambi. Ukuze ukushuba isilinganiso nalutho kuba degrees 300, futhi ikholoni - degrees 400. Ukushisisa kanye nokupholisa kancane kancane ukuqinisekisa Ukungena ezinhle metal futhi ugweme kumiswa imifantu crystallization.

Zokushisela senzeka ngokuqhubekayo usebenzisa eyodwa electrode. Akufanele zikwenze kunyakaza transverse kunensimbi.

Zokushisela tungsten electrode

Inguqulo yangaphambilini ngenxa yokuntuleka izinga kuyaqabukela esetshenziswa ochwepheshe. Namuhla amakhosi zisebenzisa uhlobo enjalo imisebenzi njengoba aluminium Welding a electrode tungsten e inert igesi emkhathini.

Le ndlela isetshenziselwa izinhlaka kumele uhlangabezane izimfuno eliphezulu. Tungsten electrode inikeza sutures namandla esiphezulu kanye sobuhle bayo.

Uma wenza umsebenzi Welding okokuvikela ebusweni aluminium kusukela namachibi argon noma helium. Arc bephethe kushintshana zamanje. Linikeza ikhefu qualitative ifilimu phezu kwensimbi.

I Ubhaqa uhambe phezu kwe wire yamathebhu, kunokuba phambi kwalo. Kufanele futhi ucabangele uhlelo ukushabalalisa ukushisa. Lokhu kubalulekile ikakhulukazi workpieces mncane.

Futhi, qaphela ukuthi eliphezulu kakhulu ukugeleza igesi engaxubani namakhemikhali kuzoholela emoyeni ukusivumela endaweni arc. Too encane okukhishwa kukho igesi noma ukusebenza ngesivinini kuzoholela yokuthi ebusweni aluminium is namanje oxidized. Argon kuyadingeka ukuze uqale ukufaka i-angu-5 arc esivuthayo. Ngemva zokugwema ukuphuka yayo igesi engaxubani namakhemikhali kuvaliwe emva 7 imizuzwana.

Njengoba bazijwayeze Welding ubuchwepheshe, abasebenzi i electrode aluminiyamu, kungenzeka ukuba bafeze le nqubo ekhaya. Nokho, ngaphambi kokuba uqale kancane kangcono eziqeqeshelwe ucezu ezingadingekile. Khona-ke umphetho ukuthola flat futhi ziqine.
