I-weld pipe weld porosity ayithinti kuphela ukuminyana kwepayipi, ukuvuza kwepayipi kanye nokugqwala kuyokwenziwa iphuzu kunciphisa kakhulu amandla okushisela kanye nokuqina.Izici ze-weld porosity yilezi: ukugeleza kwamanzi, ukungcola, i-oxide ne-iron filings, izithako zokushisela nokuqina kwekhava, ikhwalithi ephezulu yensimbi nokucutshungulwa kwamapuleti aseceleni ensimbi, ubuchwepheshe bokushisela kanye nezinqubo zokubumba insimbi.

Izinyathelo zokuvimbela ezihlobene:

1. Flux izithako.I-CaF2 ne-SiO2 equkethe inani elifanele lokushisela, ukusabela kuzomunca inani elikhulu le-H2, kukhiqize ukuzinza okuphezulu kwe-HF engancibiliki ensimbini ewuketshezi, ngaleyo ndlela kuvimbele ukwakheka kwezimbobo zegesi ye-hydrogen.

2. Ukushuba kwenqwaba ye-flux ngokuvamile kungu-25-45mm, usayizi wezinhlayiyana ezinkulu ze-solder, ihora lokuminyana ngobuningi lithatha ukujiya okuphezulu, kanti inani elincane;izinga eliphezulu lamanje, isivinini esiphansi se-welding sithatha ukushuba okuphezulu, kanti inani elincane lokwengezwa, umswakama wasehlobo noma womoya, ukubuyiswa kwe-flux kufanele komiswe ngaphambi kokusetshenziswa.

3. Ishidi lensimbi elilashwe phezulu.Ukuze ugweme i-open-book leveling off oxide scale kanye nezinye izinsalela kunqubo yokubumba, ibhodi kufanele lisethwe idivayisi yokuhlanza.

4. Steel plate onqenqemeni processing.Unqenqema lwepuleti lensimbi kufanele lusethwe ukugqwala kanye nedivayisi yokukhipha i-burr ukuze kuncishiswe ukukhiqizwa okungenzeka kwezimbobo.Ikhipha idivayisi efakwe endaweni engcono kakhulu ngemva komshini wokugaya kanye ne-disc shear, ukwakheka kwedivayisi kuwuhlangothi olusebenzayo lwesondo lezintambo ezimbili ukuya phezulu naphansi endaweni yegebe elilungisekayo, unqenqema lwepuleti lokugoqa eliphezulu naphansi.

5. Weld profile.Isici sokwenza i-Weld sincane kakhulu, sincane futhi sijulile ukuma kwe-weld, igesi nokufakwa akulula ukuvuza, kulula ukwenza ama-pores kanye ne-slag.Ukulawulwa okujwayelekile kwe-weld coefficient ku-1.3-1.5, inani eliphakeme lepayipi elinezindonga eziwugqinsi, inani eliphansi lezindonga ezincane.

6. Yehlisa indawo yesibili kazibuthe.Ukuze kuncishiswe ithonya igalelo kazibuthe kufanele kwenziwe on the workpiece Welding ikhebula uxhumano indawo kungenzeka kuphela kude esikhumulweni Welding, ukugwema ezinye ikhebula Welding yesibili field magnetic elakhiwe workpiece.

7. Umsebenzi.Kufanele kube okufanelekile ukunciphisa noma ukwandisa ijubane welding wamanje, ngaleyo ndlela ukubambezela izinga crystallization of the okugeza weld metal ukuze kube lula ukuphunyuka igesi, ngesikhathi esifanayo, uma strip ukulethwa indawo ukungazinzi, kufanele kulungiswe ngesikhathi esifanele. ukuqeda ukulungiswa okuvamile ngemva kokwamukelwa kwe-asi yangaphambili noma ibhuloho ukuze kugcinwe ukubumba, okubangela ukuba igesi ibaleke kanzima.
