Indlela yokubonisa izinga lensimbi yokushisela: Insimbi yokushisela ihlanganisa i-carbon steel yokushisela, i-alloy steel yokushisela, insimbi engagqwali yokushisela, njll. Indlela yokubonisa izinga iwukwengeza uphawu oluthi “H” ekhanda lohlobo ngalunye. welding steel grade. Isibonelo H08, H08Mn2Si, H1Cr18Ni9. Ngensimbi eshiselwe yekhwalithi ephezulu, engeza uphawu "A" ekupheleni kwebanga. Isibonelo H08A, H08Mn2SiA.

Okuvame ukusetshenziswaamapayipi ensimbi ashiselwezihlukaniswe zibe izinhlobo ezintathu ezilandelayo ngokwezinqubo zokushisela ezisetshenziswa ekukhiqizeni kwazo.
① Ukushisela kwesithando somlilo okuqhubekayo (i-forge welding) ipayipi yensimbi: Ibonakala ngokusebenza kahle kokukhiqiza okuphezulu kanye nezindleko zokukhiqiza eziphansi, kodwa inhlanganisela ye-metallurgical yejoyinti elishiselwe ayiphelele, ikhwalithi yokushisela ayilungile, futhi izici zemishini ezibanzi zimbi.

② Ukumelana nepayipi lensimbi elihlanganisiwe: Ibonakala ngokusebenza kahle kokukhiqiza okuphezulu, izinga eliphezulu lokuzenzekelayo, asikho isidingo sezinduku zokushisela kanye nokugeleza ngesikhathi sokushisela, ukulimala okuncane kwesisekelo sensimbi, nokuguqulwa okuncane nokucindezeleka okusalayo ngemva kokushisela. Kodwa-ke, imishini yayo yokukhiqiza iyinkimbinkimbi, ukutshalwa kwezimali kwemishini kuphezulu, futhi izidingo zekhwalithi yangaphezulu yamajoyini ashiselwe nazo ziphakeme kakhulu.

③Ipayipi lensimbi elishiselwe i-arc: Isici salo ukuthi ijoyinti elishiselwe lifinyelela ukuhlangana okuphelele kwe-metallurgical, futhi izakhiwo zemishini zejoyinti zingafinyelela ngokugcwele noma zibe seduze nezakhiwo zemishini zesisekelo. Ngokusho kokuma kwe-weld, amapayipi ensimbi ashiselwe i-arc angahlukaniswa abe amapayipi othungelwano oluqondile kanye namapayipi ashiselwe okuvunguzayo; ngokwezindlela ezihlukene zokuvikela ezisetshenziswa ngesikhathi sokushisela, amapayipi ensimbi ashiselwe i-arc angahlukaniswa abe amapayipi ensimbi afakwe ngaphansi kwe-arc ashiselwe kanye namapayipi ensimbi ancibilika e-arc. Kunezinhlobo ezimbili zamapayipi ensimbi ashiselwe.
