Ipayipi yensimbi ye-arc engaphansi kwamanzi isiphenduke ipayipi yensimbi yamaphrojekthi amakhulu okuthutha amafutha negesi ekhaya nakwamanye amazwe ngenxa yobukhulu bayo obukhulu bodonga, ikhwalithi enhle yezinto ezibonakalayo kanye nobuchwepheshe bokucubungula obuzinzile. Emajoyintini ashiselwe ipayipi lensimbi yensimbi enobubanzi obukhulu obukhulu, i-weld seam kanye nendawo ethinteke ukushisa yizindawo ezithambekele ekushiyekeni okuhlukahlukene, kuyilapho ama-welding undercuts, ama-pores, ama-slag inclusions, ukuhlanganiswa okunganele, ukungena okungaphelele, ama-weld bumps, ukushisa-ngokusebenzisa. , kanye nokuqhekeka kwe-welding Kuyindlela eyinhloko yesici sokushisela, futhi ngokuvamile kuba umsuka wezingozi zepayipi lensimbi ye-arc engaphansi. Izinyathelo zokulawula zimi kanje:

1. Lawula ngaphambi kokushisela:

I-1) Izinto ezisetshenziswayo kufanele zihlolwe kuqala, futhi kuphela ngemuva kokuphumelela lapho zingangena endaweni yokwakha ngokusemthethweni, futhi zisebenzise ngokuqinile insimbi engafanelekile.
2) Okwesibili ukuphathwa kwezinto zokushisela. Hlola ukuthi izinto zokushisela ziyimikhiqizo efanelekayo, ukuthi uhlelo lokugcina nokubhaka luyasetshenziswa, noma ngabe ingaphezulu lezinto ezisatshalaliswa zokushisela lihlanzekile futhi alinawo yini ukugqwala, noma ngabe ukumbozwa kwenduku yokushisela kuqinile nokuthi kukhona yini isikhutha.
3) Okwesithathu ukuphathwa okuhlanzekile kwendawo yokushisela. Hlola ukuhlanzeka kwendawo yokushisela, futhi akufanele kube khona ukungcola okufana namanzi, amafutha, ukugqwala kanye nefilimu ye-oxide, edlala indima ebalulekile ekuvimbeleni amaphutha angaphandle ku-weld.
I-4) Ukukhetha indlela yokufaka i-welding efanelekile, umgomo wokuqala we-welding welding kanye ne-welding elandelayo kufanele isetshenziswe.

2. Ukulawula ngesikhathi sokushisela:

I-1) Hlola ukuthi imininingwane ye-welding wire kanye ne-flux ilungile yini ngokuvumelana nemithethonqubo yenqubo yokushisela ukuvimbela ukusetshenziswa okungalungile kwe-welding wire kanye ne-flux futhi kubangele izingozi zokushisela.
2) Gada imvelo yokushisela. Lapho imvelo yokushisela ingeyinhle (izinga lokushisa lingaphansi kuka-0℃, umswakama ohlobene mkhulu kuno-90%), izinyathelo ezihambisanayo kufanele zithathwe ngaphambi kokushisela.
I-3) Ngaphambi kwe-welding yangaphambili, hlola ubukhulu be-groove, kufaka phakathi izikhala, imiphetho engacacile, ama-engeli kanye nokungahambi kahle, ukuthi bayahlangabezana yini nezidingo zenqubo.
4) Ukuthi i-welding current, i-welding voltage, isivinini sokushisela neminye imingcele yenqubo ekhethiwe kunqubo yokushisela ye-arc engaphansi kwamanzi ilungile.
5) Ukuqondisa abasebenzi bokushisela ukuze babusebenzise ngokugcwele ubude bepuleti le-arc lomshayeli ekupheleni kwepayipi lensimbi ngesikhathi sokushiselwa kwe-arc okuzenzakalelayo, futhi kuqinise ukusebenza kahle kwepuleti le-arc lomshayeli ngesikhathi sokushisela kwangaphakathi nangaphandle, okusiza ngcono ipayipi ekupheleni ukushisela.
I-6) Bheka ukuthi ngabe abasebenzi be-welding baqale bahlanze i-slag ngesikhathi sokukhanda i-welding, noma ngabe amalunga acutshunguliwe, kungakhathaliseki ukuthi kukhona amafutha, ukugqwala, i-slag, amanzi, upende nokunye ukungcola emseleni.
