Ipayipi lensimbi elishiselweihlukaniswe yaba izinhlobo ezimbili ngokusho Welding yayo umphetho shape-straight umphetho ipayipi steel kanye Kuvunguza steel pipe.

Ukuqina komthungo wamapayipi ensimbi akuthinti kuphela ukuminyana kokushisela kwamapayipi, okuholela ekuvuzeni kwamapayipi, futhi kuzoba indawo ebangelwa ukugqwala, kunciphisa kakhulu amandla okushisela kanye nokuqina.

Izici ze-weld porosity yilezi: ukugeleza kwamanzi, ukungcola, ne-iron oxide, ukushuba kwezingxenye ezishiselwe nokumbozwa, kanye nekhwalithi yangaphezulu yamapuleti aseceleni okucubungula amashidi ensimbi, inqubo yokushisela kanye nenqubo yokwenza ipayipi nokunye.

Izinyathelo zokulawula ezifanele zimi kanje:

1.Ingxenye ye-flux.Lapho iqukethe inani elifanele le-CaF2 ne-SiO2, ukucutshungulwa kokushisela kuzomunca inani elikhulu le-H2, futhi kukhiqize i-HF enokusimama okuphezulu futhi engancibiliki kunsimbi ewuketshezi, ngaleyo ndlela kuvimbele ukwakheka kwegesi ye-hydrogen. izimbobo.

2.Ukunqwabelana kokuguquguquka kuvamise ukuba ngu-25-45mm.Uma i-Flux inedigri yezinhlayiya ezinkulu kanye nokuminyana okuncane, thatha ukushuba okuphezulu kakhulu kokunqwabelana, kuyilapho inani elincane;yamanje ephezulu, isivinini esiphansi sokushisela sithatha ubukhulu obukhulu, kanti inani elincane.Ngaphandle kwalokho, lapho ehlobo noma ezinsukwini ezinomswakama ophezulu, ukubuyiswa kwe-flux kufanele komiswe ngaphambi kokusetshenziswa.

3 Ukwelashwa kwendawo yensimbi.Ukuze ugweme ukuqaqa i-iron oxide nezinye izinsalela eziwela ekubumbeni, umshini wokuhlanza ibhodi kufanele umiswe.

4 Ukwelashwa kwamapuleti ensimbi.Idivayisi yokukhipha ukugqwala nama-burrs kufanele isethwe onqenqemeni lwepuleti lensimbi ukuze kuncishiswe amathuba okwakheka kwe-porosity.Indawo engcono kakhulu yokufaka idivayisi ecacile iseduze nemishini yokugaya i-disc cutting edge, isakhiwo sedivayisi yisondo elisebenzayo ngenkathi igebe eliguquguqukayo lezikhundla ezimbili phansi, phezulu naphansi emiphethweni yepuleti lokucindezela.

5 Iphrofayili yomugqa wokushisela.I-Welding form factor incane kakhulu, ukwakheka kwe-weld kuncane futhi kujulile, igesi nokufakwa akulula ukuphumela ngaphandle futhi kulula ukwenza izimbotshana kanye ne-slag.Ukulawulwa kwesici esijwayelekile sokushisela ku-1.3-1.5, ipayipi elinezindonga eziwugqinsi khetha inani eliphezulu, kanye nenani eliphansi lezindonga ezincane.

6 Ukunciphisa insimu kazibuthe yesibili.Ukuze kuncishiswe imiphumela yokushaywa kazibuthe, indawo yesixhumi endaweni yokusebenza kufanele iqhelelene nengxenye yetheminali yekhebula yokushisela ukuze kugwenywe inkambu kazibuthe yesibili ekhiqizwa kucezu lokusebenza.

7 Ubuchwepheshe:Kufanele inciphise ngokufanele isivinini sokushisela noma ikhulise okwamanje, ngaleyo ndlela ibambezele izinga lokucwebezeliswa kwensimbi yokugezela, ukuze kube lula ukukhulula igesi, kuyilapho uma indawo yokulethwa ingazinzile, umucu kufanele ulungiswe ngesikhathi ukuze uqede igesi. i-asi yangaphambili ngokusikwa njalo noma ukwakheka kwebhuloho, okubangela ukuba igesi ibaleke kanzima.
