Arc welding e ka aroloa kaho tjheseletsa arc ka letsoho, semi-automatic (arc) welding, automatic (arc) welding. Othomathiki (arc) welding hangata e bua ka ho tjheseletsa ka ho iketsa arc - sebaka sa welding se koahetsoe ka lera le sireletsang la flux, terata ea photonic e entsoeng ka tšepe ea tšepe e kenngoa ka har'a lesela la flux, 'me tšepe ea welding e hlahisa arc, arc e patoa tlas'a lera la flux,' me mocheso o hlahisoang ke arc o qhibilihisa terata ea weld, terata ea weld, le tšepe e entsoeng ka tšepe e entsoeng ka motlakase. E sebelisoang haholo ke manual arc welding.
2.Mokhoa oa motheo

Karolo ea groove ke ho etsa molamu oa ho tjheseletsa, terata ea welding kapa toche (nozzle e fafatsang lelakabe la acetylene-oksijene nakong ea ho cheselletsa khase) ka ho toba ka tlase ho groove ho netefatsa ho kenella ha welding, 'me e thusa ho tlosoa ha slag le ho thusa ho oscillation ho hlokahalang ha molamu oa ho tjheseletsa ho fumana molamu o motle. Sebopeho le boholo ba groove haholo-holo itšetlehile ka thepa welded le litlhaloso tsa eona (haholo-holo botenya), hammoho le mokhoa oa ho tjheseletsa o amohetsweng, mofuta oa weld seam, joalo-joalo Mefuta e tloaelehileng ea grooved ka likopo tse sebetsang ke: manonyeletso a kobehileng - a loketse likarolo tse tšesaane tse nang le botenya ba <3mm; Flat groove - e loketseng likarolo tse tšesaane tsa 3 ~ 8mm; groove e nang le sebopeho sa V - e loketse lisebelisoa tsa mosebetsi tse nang le botenya ba 6 ~ 20mm (welding e nang le lehlakore le le leng); Setšoantšo sa schematic sa weld groove mofuta oa X-mofuta oa groove - o loketse lisebelisoa tsa mosebetsi tse nang le botenya ba 12 ~ 40mm, 'me ho na le li-groove tsa X tse nang le symmetrical le asymmetrical (welding e nang le mahlakore a mabeli); Groove e nang le sebopeho sa U - e loketse lisebelisoa tsa mosebetsi tse nang le botenya ba 20 ~ 50mm (welding e nang le lehlakore le le leng); Sefate sa U-shaped groove - se loketse lisebelisoa tsa mosebetsi tse nang le botenya ba 30 ~ 80mm (welding e nang le mahlakore a mabeli). The groove angle hangata e nkoa ho tloha 60 ho 70 °, 'me morero oa ho sebelisa metshetshe e lerootho (hape e bitsoa bophahamo ba metso) ke ho thibela weldment hore e se ke ea tuka, ha lekhalo e le ho thusa ho kenella ka tjheseletsa.
