Vim muaj ntau yam, tsis xws luag xws li cua qhov, pinhole, slag suav nrog, tawg, qhov thiab lwm yam feem ntau tshwm sim nyob rau hauv ductile hlau castings. Cov khoom siv kho mob feem ntau yog argon arc vuam tshuab, tsis siv neeg vuam tshuab, vuam tshuab txias, thiab lwm yam., uas muaj kev cuam tshuam tseem ceeb ntawm qhov zoo, raug nqi, kev tsim khoom, kev siv zog, kev ua qias tuaj ib puag ncig thiab lwm yam ntawm ductile castings. Ntev npaum li cov txheej txheem molding thiab cov txheej txheem tseem ceeb yog tswj tau zoo, qhov zoo ntawm nodular cam khwb cia slab tuaj yeem txhim kho.
Thaum nqa lub phaj ntawm nodular casting, txhawm rau tiv thaiv kom tsis txhob deformation ntawm lub phaj ntawm nodular casting, plaub hlau hlau hlua ntawm tib qhov ntev yuav tsum tau siv los dai plaub qhov lifting qhov ntawm lub phaj ntawm nodular casting tib lub sijhawm, thiab phaj ntawm nodular casting yuav tsum ruaj khov nqa ntawm cov cuab yeej thauj mus los. Cov ntsiab lus txhawb nqa ntawm lub phaj ntawm cov yeeb nkab casting yuav tsum zoo padded thiab leveled. Txhua qhov chaw txhawb nqa yuav tsum sib npaug sib npaug thiab tag nrho cov phaj ntawm cov hlua hlau yuav tsum ruaj khov. Txhawm rau tiv thaiv tag nrho cov deformation ntawm cov ductile casting phaj, lub workpiece yuav tsum tau muab tshem tawm los ntawm cov ductile casting phaj tom qab siv los tiv thaiv lub deformation ntawm cov ductile casting phaj uas tshwm sim los ntawm lub workpiece lub sij hawm ntev hnyav nias ntawm lub ductile casting phaj.
Vuam thev naus laus zis yuav koom nrog ntau cov txheej txheem, suav nrog nodular cam khwb cia hlau. Cov txheej txheem vuam ntawm no yog cov roj welding thiab phau ntawv arc vuam, sib xws rau cov vuam hlau sib txawv thiab kev kho mob. Rau cov roj vuam, RZCQ hom ductile casting vuam hlau yog siv, thaum CJ201 yog siv los ua flux thiab txo cov nplaim taws yog siv cov nplaim taws. Nyob rau hauv cov ntaub ntawv ntawm kev ua cov castings nrog complex qauv los yog ductile hlau castings, kub welding thiab qeeb txias tom qab vuam kuj yuav tsum tau.
Thaum ntsib homogeneous weld, lub electrode rau phau ntawv arc vuam yog EZCQ hlau puag nodular casting electrode; Ua ntej welding, lub workpiece yuav tsum tau preheated. Nyob rau tib lub sijhawm, tom qab vuam, nws yuav tsum tau khaws cia kom sov thiab maj mam txias. Tom qab annealing thiab vuam, txiav tuaj yeem nqa tawm. Cov txheej txheem vuam loj tam sim no thiab txuas ntxiv yuav tsum tau txais thaum lub sij hawm vuam, thiab cov vuam tam sim no kuj yuav raug xaiv kom tsim nyog.
Thaum siv cov vuam vuam sib txawv, cov hlua vuam yuav tsum tau hloov. Cov txheej txheem vuam txias yuav tsum tau ua raws li nruj me ntsis thaum vuam, thiab cov txheej txheem txiav tsuas yog ua tau tom qab vuam txias.
