Kev kho cua sov tom qab vuam kuj tseem muaj nqis. Nws tuaj yeem txo cov kev ntxhov siab ntxiv, kho cov microstructure, thiab txhim kho cov cuab yeej cuab tam ntawm cov vuam thiab thaj chaw uas muaj cua sov. Annealing lossis tempering kev kho mob tuaj yeem siv tau raws li qhov yuav tsum tau ua.
Kev siv cov hlau ua kom haum thiab cov fluxes yog qhov tseem ceeb. Qhov sib xyaw ntawm cov hlau muab tub lim yuav tsum sib haum nrog cov hlau hauv paus kom ntseeg tau tias kev sib txuas zoo ntawm cov hlau thiab tsis txhob tsim cov theem nkig los yog qhov tsis xws luag ntawm qhov sib txuas.
Kev tswj qhov chaw vuam yog qhov tseem ceeb thiab. Ua kom qhov chaw vuam huv, qhuav, thiab tsis muaj kab mob yuav pab tiv thaiv porosity thiab lwm yam tsis xws luag hauv qhov vuam.
Tsis tas li ntawd, kev siv cov kev tswj xyuas nruj thiab cov txheej txheem tshuaj xyuas thoob plaws hauv txoj kev vuam yog tsim nyog. Kev kuaj xyuas tsis tu ncua ntawm cov khoom siv vuam, cov ntaub ntawv tsim nyog, thiab cov txheej txheem kuaj tsis muaj kev puas tsuaj tuaj yeem ua kom ntseeg tau tias cov pob qij txha welded ua tau raws li cov qauv xav tau.
Hauv kev xaus, kev txhim kho lub weldability ntawm BV Qib A Nkoj Hlau Phaj muaj kev sib xyaw ua ke ntawm kev ua kom zoo ntawm cov hlau muaj pes tsawg leeg, siv cov preheating tsim nyog thiab kev kho tom qab vuam, xaiv cov txheej txheem vuam thiab tsis zoo, siv cov khoom siv tsim nyog, tswj ib puag ncig, thiab tswj xyuas nruj. kev tswj kom zoo.
Thov nco ntsoov tias cov txheej txheem tshwj xeeb thiab lawv cov txiaj ntsig tuaj yeem sib txawv nyob ntawm qhov tshwj xeeb thiab cov kev xav tau ntawm txhua daim ntawv thov vuam.
