1.1 weldability na chromum molybdenum zafi mai tsayayya da karfe
Chromium da Molybdenum manyan abubuwa ne masu kyau, mai zafi mai zafi {0} resistant na sararin samaniya martani wanda yake da tsari mai ƙarfi da kuma zafi ya shafi tsarin kayan aiki, ba wai kawai yana shafar kayan aikin na ba Welded haɗin gwiwa, kuma samar da danniya da yawa, don haka irin sanyi crack hali.
Sabili da haka, babban matsalar zafi mai tsayayya da ƙarfe waldight shine fasa, kuma samuwar fasahohi ne guda uku: tsari, damuwa da hydrogen tsari na weld.
2.1 Groove
Yin tsinkaye aiki yawanci ana yin shi ne ta harshen wuta ko tsarin yankan plamai. Lokacin da ya cancanta, ya kamata kuma a sami matsala, kuma za'a yi binciken PT bayan pt bayan pT don cire fasa a kan tsagi. Yawancin lokaci zaɓi V -} iren tsagi, digiri na 60 digiri ne mai yawa, amma ƙara yawan walkiya da sauran datti (hydrogen, hana porolonity).
2.2 sa
Neman tilasta kungiyar don hana samar da damuwa na ciki, saboda tsayin daka, welting jama'a crudanya, don kada ya haifar da welding mai ban sha'awa, don kada ya haifar da welding mai ban sha'awa, don kada ya haifar da welding na hanzari, don kada ya haifar da welding mai ban sha'awa, don kada ya haifar da welding mai ban sha'awa, don kada ya haifar da welding mai ban sha'awa, don kada ya haifar da wuce gona da iri, don kada ya haifar da welding free shrinkage, Jig da tsayawa, ya kamata a guji amfani.
2.3 Zabi na Hanyar Welding
A halin yanzu, hanyoyin da ake amfani da su na yau da kullun don walda a cikin man fetur da kuma raka'an shigarwa na elechode don murfin. Other welding methods include MIG welding, CO2 gas welding, electroslag welding and automatic submerged arc welding, etc.
2.4 zaɓi na kayan waldi
Ka'idar zabar kayan waldi, kayan kwalliyar allon da kuma ƙarfin aikin ƙarfe na ƙarfe ko kuma ya isa ga yanayin fasaha wanda aka gabatar da yanayin fasahar samfurin. Kuma don rage abun ciki na hydrogen ya kasance tare da alkaline low hydrogen nau'in electrode, in ba haka ba na bushewa, ya kamata ya ci gaba da bushewa, lokutan bushewa bazai zama fiye da sau uku ba, A kan aiwatar da ingantaccen ginin gini, suna da cikakken abinci. Hakanan ana iya amfani da bakin karfe mara nauyi, kamar a cikin 1007, kuma ana iya amfani dashi don walƙen Chromium- heat} heat molybdenum zafi. Wannan hanyar ta dace da lamarin da waldi bangarorin ba za su iya yin zafi ba bayan waldi.
2.5 Samfurin
Preheating ma'aunin fasaha ne don crack crack da kuma kawar da yanayin waldi mai zafi {{0} mai tsayayya da karfe. Don tabbatar da walwala mai kyau, preheating da kuma rike wani adadin zafin jiki ya kamata a aiwatar da shi a cikin duka tabo gyara da kuma tsarin walding.
2.6 jinkirin sanyaya bayan waldi
Bayan waldi mai jinkirin sanyaya shine ka'idar waldenum huhun sanyi na motheldos na rufe wannan, koda kuwa ana iya sanya weld kuma kusa da seam.
2.7 post -
Ya kamata a nemo magani mai zafi nan da nan bayan waldi don hana lalata fashewa, kawar da damuwa da haɓaka microstructure.
