Cov yam ntxwv ntawmvuamqhov tsis xws luag

(1) Khoom siv:

Lub npe hu ua cov khoom tseem ceeb yog hais txog kev sib txuas ntawm cov hlau thiab cov khoom siv vuam siv, xws li cov xov hlau, cov pas nrig, flux, thiab cov roj tiv thaiv thiab lwm yam.Tag nrho cov ntaub ntawv no yog ncaj qha mus rau hauv lub vuam pas dej los yog physico-tshuaj cov tshuaj tiv thaiv ntawm lub fusion zone, qhov twg lub hauv paus ntawm kev ua tau zoo ntawm cov khoom nws tus kheej, dual-zones tshav kub duab ntxoov ntxoo tua decisive cuam tshuam.Ntawm qhov muaj pes tsawg leeg thiab cov khoom ntawm cov hlau welding kuj yog ib qho tseem ceeb ntawm cov khoom siv vuam siv kom meej.Cov txiv hmab txiv ntoo zoo thiab lub hauv paus hlau vuam cov ntaub ntawv tsis sib haum, tsis tsuas yog tuaj yeem ua rau muaj ntau yam tsis xws luag hauv thaj chaw weld mus rau cov kab, qhov hws, thiab lwm yam, thiab kuj tuaj yeem muaj los ntawm embrittlement, corrosion-resistant zog kom soften lossis hloov.Yog li ntawd, txhawm rau txhawm rau ua kom zoo weld pob qij txha yuav tsum tau ua tib zoo saib xyuas cov khoom siv.

(2) Cov txheej txheem thev naus laus zis:

Ntau qhov kev xyaum tau ua pov thawj tias tib yam ntawm cov hlau hauv cov txheej txheem vuam sib txawv thiab cov txheej txheem ntsuas cov xwm txheej, qhov vuam zoo yuav qhia qhov sib txawv loj.Muaj feem xyuam rau qhov zoo ntawm txoj kev vuam ntawm vuam lub ntsiab ua tau nyob rau hauv ob yam: Ua ntej, cov yam ntxwv ntawm lub vuam kub qhov chaw, uas yog lub hwj chim ceev, lub siab tshaj plaws cua sov kub, lub hwj chim theem, thiab lwm yam., lawv muaj peev xwm hloov qhov tsis zoo ntawm vuam. thermal voj voog ncaj qha, xws li cov kab ntawm lub zog, lub sij hawm nyob rau hauv high-temperature, lub sij hawm hloov pauv qhov kub thiab txias ntawm qhov ntsuas kub.Cov no tau kawg yuav cuam tshuam rau microstructure thiab cov khoom ntawm cov pob qij txha;thib ob rau lub pas dej ua ke thiab thaj chaw nyob ze ntawm kev tiv thaiv, xws li kev tiv thaiv slag, roj, roj - slag sib koom tiv thaiv los yog vuam hauv lub tshuab nqus tsev, uas yuav cuam tshuam rau cov txheej txheem ntawm vuam metallurgy.Obviously, cov txheej txheem ntawm vuam thermal thiab metallurgical txheej txheem rau kev ua tau zoo thiab kev ua tau zoo yuav inevitably sib koom tes txiav txim siab.
