Ipayipi lensimbi yokushisela kuyinqubo evamile edlala indima ebalulekile ekwakhiweni, ekukhiqizeni nasekulungiseni amasimu. Kodwa-ke, lapho senza imisebenzi yokushisela, sidinga ukunaka ezinye izinto ezibalulekile ukuze siqinisekise ikhwalithi nokuphepha kokushisela.

Okokuqala, ukulungiselela ngaphambi kokushisela ipayipi lensimbi kubalulekile. Ngaphambi kokuthi uqale ukushisela, qiniseka ukuthi unamakhono afanele okushisela kanye nolwazi futhi ugqoke izinto zokuzivikela ezifanele, njengemaski eshiselayo, amagilavu, nezingubo ezingashi. Futhi, qiniseka ukuthi indawo yokusebenza ihlanzekile, ikude nezinto ezivuthayo, futhi ugcine umoya ofanele ukuze ugweme ukunqwabelana kwamagesi ayingozi.

Okwesibili, ukukhethwa okufanele kwezinto zokushisela kanye nemishini nakho kubaluleke kakhulu. Qinisekisa ukuthi induku yokushisela ekhethiwe noma ucingo lufana nempahla yepayipi lensimbi, bese ukhetha i-welding current ne-voltage efanele ngokuya ngokucaciswa nokushuba kwepayipi lensimbi. Ngesikhathi esifanayo, qiniseka ukuthi imishini yokushisela isebenza kahle, i-voltage yokuhlinzeka amandla izinzile, futhi ikhebula lokushisela libekwe kahle ukuze kuqinisekiswe ukuzinza nokuphepha kwenqubo yokushisela.

Okulandelayo, lapho ufaka amapayipi ensimbi, udinga ukunaka ukulungiswa nokuphathwa kwamalunga ahlanganisiwe. Qinisekisa ukuthi zombili iziphetho zejoyinti ziyisicaba futhi azinawo uwoyela nokungcola, futhi usebenzise amathuluzi afanelekile okushaya, ukuchama, nokuhlanza. Ngaphambi kokushisela, sebenzisa izindlela ezifanele zokushisa ukushisa ukushisa kwendawo yokushisela ukuze unciphise ukucindezeleka kokushisela futhi uthuthukise ikhwalithi yokushisela.

Lapho wenza i-welding yangempela, qaphela ubuchwepheshe be-welding kanye nezici zokusebenza. Bazi kahle amakhono afanele wokushisela, futhi ugcine ukuma okuzinzile kanye nesivinini sokushisela. Lapho ushisela, gcina ubude be-arc obufanele kanye ne-engeli yokushisela, futhi ulawule amandla okushisela kanye ne-voltage ukuze uqinisekise ukufana nokuqina kwe-weld.

Ekugcineni, ngemva kokuphothulwa kwe-welding, ukucubungula kwe-weld kwenziwa ngesikhathi esifanele. Hlanza i-slag yokushisela nama-oxide ebusweni be-weld, futhi ugaye futhi upholishe i-weld ukuze uthuthukise ukubukeka kwayo nokumelana nokugqwala. Ngasikhathi sinye, ukuhlolwa okudingekile okungabhubhisi kanye nokuhlolwa kwempahla eyimishini kwenziwa ukuze kuqinisekiswe ukuthi ikhwalithi yokushisela ihlangabezana nezidingo.

Ukufingqa, kunezinto eziningi okufanele uzinake lapho ushisela amapayipi ensimbi. Kusukela ekulungiseni ngaphambi kokushisela ukuya ekusebenzeni kokushisela kuya ekwelashweni kwangemuva kokushisela, sonke isixhumanisi sibalulekile. Kuphela ngokulandela izicaciso ezifanele zokusebenza, ukwazi amasu okushisela afanelekile, nokunaka ukuhlolwa kwekhwalithi lapho singaqinisekisa ikhwalithi nokuphepha kwamapayipi ensimbi ashiselwe.
