Isiphetho
Izinhlobo zemishini yokushisela
Kunezinhlobo ezahlukene zemishini yokushisela, ngayinye inezinhlelo zayo ezithize. Isibonelo, eminye imishini ingcono kakhulu ukusetshenziswa endlini, kanti eminye ingcono kakhulu kwangaphandle.
Imishini yokushisela igesi yensimbi inert
Umshini wokushisela we-metal inert gas (MIG) uwuhlobo lomshini wokushisela i-arc owenza i-weld isebenzisa igesi evikelayo kanye ne-electrode yocingo ephakelwa ngokuqhubekayo. Imishini yokushisela ye-MIG sebenzisa izintambo ezingenalutho kanye nama-flux cores. Intambo engenalutho ishisela izingcezu ezincane zensimbi, futhi ingasetshenziswa ngaphandle ngaphandle kokunikezwa kwegesi.
I-MIG imishini yokushisela asetshenziswa kakhulu embonini yezimoto ngoba ashisela izinto ezincane ngokushesha futhi kalula. Ngaphezu kwalokho, abaqalayo bavamise ukusebenzisa i-MIG welding njengoba ishibhile futhi kulula ukuyifunda.

- Ingasetshenziswa ezintweni ezihlukahlukene
- Ivumela umshiseli ukuthi alawule inqubo yokushisela
- Ikhiqiza intuthu encane kanye nentuthu
Okumbi
- Inqubo enensayo, iyenza ingasebenzi kahle kunezinye izinqubo
- Idinga izinga eliphezulu lekhono nolwazi
- Ayifanelekile ukushisela izinto eziwugqinsi
- Imishini ibiza kakhulu
Umshini wokushisela induku
Eyaziwa nangokuthi i-shielded metal arc welding (SWAM), imishini yokushisela induku isebenzisa i-electrode esetshenziswayo ehlanganiswe ngo-flux ukuze yenze i-weld. Imishini yokushisela induku zivame ukusetshenziswa emsebenzini wokwakha nokulungisa ngoba ziyakwazi ukushisela izinto eziwugqinsi.
Imishini yokushisela izinti nayo iyonga njengoba isebenzisa ugesi omncane ukwenza amashisela aqinile. Ngaphezu kwalokho, imishini ngokuvamile ishibhile, okuyenza ibe yisinqumo esifiselekayo sokusetshenzwa kochwepheshe nokomuntu siqu.
Izinzuzo

- Angakwazi ukushisela izinto eziwugqinsi
Okumbi
- Ikhiqiza intuthu eningi kanye nentuthu
- Kudinga ukusetshenziswa kwe-electrode ene-flux-coated, engase ibe ngcolile
- Ikhiqiza i-weld enembe kancane kunezinye izinqubo nemishini yokushisela
Umshini wokushisela we-Plasma arc
Imishini yokushisela i-Plasma arc isebenzisa ijethi enesivinini esikhulu segesi eyonisiwe ukudala i-weld. Imishini ye-Plasma arc ingasetshenziselwa ukushisela izinto okunzima ukuzishisela usebenzisa ezinye izindlela ezifana ne-titanium nama-super alloys.
Imishini yokushisela i-Plasma arc zifana nemishini ye-TIG kodwa zine-anode ezungeze i-electrode ye-tungsten, ebopha i-arc futhi ivumela ukuhloswa kwe-laser-nemba. Imishini yokushisela i-Plasma arc isetshenziswa ngokuyinhloko embonini ye-aerospace.
