I arc kuyinto: Incazelo kanye nezici

I arc kuyinto osenyameni arc okuyinto eyenzeka phakathi electrode amabili noma electrode kanye workpiece futhi elivumela ukukhiqiza elibona nxazonke izingcezu ezimbili nofana ezinengi ngokuzibeka enye Welding.

I arc Welding kuncike imvelo lapho kwenzeka, ihlukaniswe yaba amaqembu amaningana. Kungenzeka evulekile, ivaliwe, futhi igesi ukuzivikela.

Vula arc ageleza ngaphandle ngokusebenzisa ionization e amandla omlilo izinhlayiya, kanye ngentukuthelo zensimbi izingxenye ashiselwe we indaba electrode. arc Kuvaliwe yena, izibani kwamanzi. Lokhu kuvumela ukushintsha indlela yokwakheka medium gaseous kule amandla omlilo futhi ukuvikela metal kusukela namachibi izikhala. I arc ke odabula ion umusi metal kanye okufakiwe yokucucuza. I arc, okuyinto evutha ukuzivikela igesi odabula ion igesi kanye evala metal. Lokhu kuyasiza ekuvimbeleni namachibi izingxenye, futhi kungakho ukwandisa nokwethenjelwa kwakhiwa kwakwakhe.

I arc kuyahluka ubunjalo enikeziwe wamanje - njalo noma variable - kanti isikhathi amandla omlilo - ishayela noma umile. Ngaphezu kwalokho, arc kungaba ngokuqondile noma ukubuyisela emuva polarity.

Ngokusho uhlobo electrode esetshenziswa ukuhlukanisa non-consumable futhi ukuncibilika. Ukusetshenziswa eyodwa noma enye yezinto electrode incike izici possessed umshini Welding. I arc ephakama uma usebenzisa electrode non-consumable, njengoba leli gama lisikisela, akusho deform ke. Ngo Welding nge consumable electrode arc zamanje liyancibilika okokusebenza futhi ashiselwe kuya preform yasekuqaleni.

Igebe arc kungenziwa ihlukaniswe yaba izifunda ezintathu isici: precathode, pre-anode, futhi kushaft arc. Kulesi Umusho wokugcina, okusho isiqu arc uye ubude esiphezulu Nokho, izici arc, kanye nokwenzeka lapho ivela khona kunqunywa izifunda okoloelektrodnymi.

Ngokuvamile, izici possessed arc kagesi, zingahlanganiswa ohlwini olulandelayo:

1. Ubude arc. Lokhu kusho ibanga isamba cathode nesifunda anode, kanye arc umgqomo.

2. voltage we arc. Kuyinto isamba voltage lehla ngamunye ezindaweni: isiqu, eduze cathode kanye anode. Ushintsho voltage izindawo okoloelektrodnyh kuningi kunokomuntu endaweni esele.

3. Izinga lokushisa. I arc kuye ukubunjwa medium gaseous, indaba electrode kanye kwabantu kwamanje kungaba afinyelele ezingeni lokushisa kuze kufinyelele ayizinkulungwane 12 degrees Kelvin. Nokho, la magquma kungukuthi wahlela yonkana endizeni ekupheleni electrode. Ngoba ngisho ukwelashwa okungcono ku indaba of the conductive ingxenye unamaqhubu ehlukahlukene uhlevane, sibonga ngalo kukhona isethi izingcezu, okuyinto ziqondakala njengenye. Yiqiniso, ixhomeke lokushisa arc imvelo lapho siyavutha, kanye nemingcele ihlinzekwa zamanje. Ngokwesibonelo, uma thina ukwandisa inani lamanje ukuthi, ngokufanele, ukwandisa inani lokushisa.

Ekugcineni, izici zamanje yamandla aphindeke kabili noma zamanje yamandla aphindeke kabili izici. Limelela kwencika voltage we obuphelele nokubaluleka wamanje.
