Kauv welding yog txheej txheem uas siv tas li nkag mus rau MIG surfacing los tsim kev puas tsuaj los ntawm kev hnav, yaig, corrosion, los yog tawg, los yog ua kom qhov loj ntawm ib feem kom phim qhov loj me ntawm cov mating tivthaiv. Kev siv cov txheej txheem kauv vuam tshem tawm qhov tsis sib xws ntawm qhov uas yuav tshwm sim los ntawm kev ntxhov siab tsis sib xws hauv cov txheej txheem vuam ib txwm. Kauv welding yog cov txheej txheem qis-zog input uas cov txheej txheem ntawm cov vuam thiab lawv cov cheeb tsam cuam tshuam los ntawm cua sov yog tempered thiab cov qauv nplej tau ua kom zoo dua los ntawm cov hlaws tom ntej thiab sib tshooj tempering.
Kauv vuam siv tau los kho thiab txhim kho cov khoom hauv cov txheej txheem remanufacturing. Cheebtsam tuaj yeem txhim kho los ntawm cov txheej txheem no los ntawm kev siv cov ntaub ntawv npog zoo tshaj plaws; Qhov no yog nyob ntawm ob qho kev qhia dav dav:
Kev sib piv ntawm cov khoom siv niam txiv rau cov xaim xaim ntawm tib lossis ze tshaj plaws uas muaj cov khoom xaiv.
Kev siv cov ntaub ntawv npog sib txawv los txhim kho kev tiv thaiv corrosion, yaig lossis hnav.
Tom qab-weld grain qauv nyob rau hauv lub weld thiab nyob rau hauv lub tshav kub cuam tshuam cheeb tsam yuav tsum tau xav txog. Ntxiv rau qhov no, xws li qhov sib txawv ntawm coefficients ntawm thermal expansion, lub zog thiab ductility ntawm ob cov ntaub ntawv sib txawv, thiab muaj peev xwm ntawm galvanic coupling ntawm ob cov ntaub ntawv los yog lwm yam txuas. Ua tib zoo xav txog cov txheeb ze coefficients ntawm thermal expansion yog qhov tsim nyog los xyuas kom meej tias cov kab mob hauv cheeb tsam ntawm qhov sib cuam tshuam ntawm cladding thiab cov khoom siv hauv paus tsis pub tshaj qhov tau txais txiaj ntsig thaum lub sij hawm vuam / kho cua sov los yog hauv kev pabcuam.
Kev kho cua sov ua ntej thiab tom qab vuam yog qhov tseem ceeb. Kev siv preheating nrog rau kev ua tib zoo xaiv qhov chaw kho mob thiab kev siv cov khoom siv hluav taws xob tsawg, hydrogen-resistant, nws tus kheej siv cov xov hlau tshem tawm cov kev pheej hmoo ntawm hydrogen tawg thaum lub sij hawm vuam txheej txheem. Kev kho cua sov tom qab vuam yog siv los tswj cov teeb meem tseem ceeb ntawm kev hloov pauv ntawm cov matrix mus rau cov qauv martensitic untempered thaum tus txheej txheem.
