Kuyini ukungena kwe-welding?Kubhekiselwa ekujuleni kokuncibilika kwensimbi eyisisekelo noma ubuhlalu obuyi-weld obungaphambili engxenyeni yesiphambano sejoyinti elishiselwe.
Amajoyinti ashiselwe afaka: i-weld seam (0A), indawo yokuhlanganisa (AB) nendawo ethintekile ekushiseni (BC).
Isinyathelo 1: Isampula
(1) Indawo yokusika yesampula yokungena yokushisela: a.Gwema ukuqala nokumisa izikhundla
b.Sika ku-1/3 yesibazi se-weld
c.Uma ubude besibazi sokushisela bungaphansi kuka-20mm, nqunywa phakathi nesibazi sokushisela.
(2) Ukusika
A. Xhuma ugesi futhi uhlole ukuthi okokukala kuyahlangabezana yini nezidingo zokuhlola;Njengoba kuboniswe kuMfanekiso 1, vula indlu yokuvikela yomshini wokusika i-metallographic bese ufaka ibhulokhi yesampula yensimbi ezohlolwa.
(Qaphela: Qiniseka ukuthi uyilungisa ngokuphelele insimbi!)
b.Njengoba kuboniswe kuMfanekiso 2, vala igobolondo elivikelayo lomshini wokusika i-metallographic, vula i-valve yamanzi, bese uvula inkinobho yamandla;Bamba isibambo somshini wokusika i-metallographic bese usicindezela kancane usike phansi ukuze usike isampula yensimbi.Ngemva kokusika, ubude, ububanzi nokuphakama kwesampula yensimbi kuyoba ngaphansi kuka-4mm;Vala i-valve yamanzi, vala amandla, bese ukhipha isampula yensimbi.
b.Njengoba kuboniswe kuMfanekiso 2, vala igobolondo elivikelayo lomshini wokusika i-metallographic, vula i-valve yamanzi, bese uvula inkinobho yamandla;Bamba isibambo somshini wokusika i-metallographic bese usicindezela kancane usike phansi ukuze usike isampula yensimbi.Ngemva kokusika, ubude, ububanzi nokuphakama kwesampula yensimbi kuyoba ngaphansi kuka-4mm;Vala i-valve yamanzi, vala amandla, bese ukhipha isampula yensimbi.
Isinyathelo sesi-3: Ukugqwala
(1) Njengoba kuboniswe kumfanekiso wesi-5, sebenzisa utshwala obuphelele ne-nitric acid ukuze ulungise isixazululo sokugqwala (3-5% i-nitric acid notshwala) enkomishini yokulinganisa, faka isampula yensimbi kusixazululo sokugqwala noma usebenzise ibhulashi elincane ukugeza. indawo esikiwe yokugqwala.Isikhathi sokugqwala singamasekhondi ayi-10-15, futhi umphumela wokugqwala othize udinga ukubukwa ngokubonakalayo.
(2) Njengoba kubonisiwe kumfanekiso wesi-6, ngemva kokugqwala, khipha isampula yensimbi nge-tweezers (inothi: ungathinti uketshezi olugqwala ngezandla), bese uhlanza isixazululo sokugqwala endaweni yesampula yensimbi ngokuhlanzekile. amanzi.

Isinyathelo sesi-4: Indlela yokuhlola yokungena kwe-welding
| I-T (mm) ubukhulu bepuleti | |||
| Ibhentshimakhi endala | Ibhentshimakhi entsha | ||
| Ukujiya kwepuleti | Idatha yokungena | Ukujiya kwepuleti | Idatha yokungena |

(1.2) Idatha yokungena yokushisela (onobude bomlenze obubonisa ukungena)
| U-L (mm) ubude bonyawo | |
| Ubude bonyawo | Idatha yokungena |
| L≤8 | Ngaphezulu kuka-0.2 * L |
| L＞8 | ngaphezu kwe-1.5 mm |
(2) Isilinganiso sokungena kokushisela (ibanga elingu-a no-b wukungena kokushisela)
(3) Amathuluzi okuhlola okungena kwe-welding
Isinyathelo sesi-5: Umbiko wokuhlolwa wokungena kwe-welding nokugcinwa kwamasampula
(1) Umbiko wokuhlola ukungena kokushisela:
a.Ukwengezwa komdwebo wesigaba esiphambanayo sengxenye ehloliwe
b.Maka indawo yokulinganisa yokungena kwe-welding emdwebeni
c.Ukwengezwa kwedatha
(2) Imithethonqubo yokulondolozwa kwamasampula okungena kokushisela:
a.Ukugcinwa kwezingxenye zohlaka S iminyaka engu-13
b.Izingxenye ezijwayelekile zizogcinwa iminyaka emi-3
c.Uma kuchazwe ngenye indlela emdwebeni, kuzosetshenziswa ngokuvumelana nezidingo zomdwebo
(Indawo yokuhlola ukungena ingabhajwa ngokunamathela obala ukuze kubambezeleke ukugqwala)
