S235 J0 KAUV STEEL YEE - Kev ua si zoo ntawm txoj kab uas nyob loj tshaj wrded yeeb nkab
Peb txaus siab los qhia peb cov khoom lag luam saum-cov kab,S235 J0 KAUV STEEL YEEB, tsim kom tau raws li cov kev xav tau loj hlob ntawm ntau yam kev lag luam. Raws li cov chaw tsim khoom lag luam hauv lub tshav pob, peb siv cov thev naus laus zis siab thiab kev txawj ntse los tsim cov khoom zoo siabKab Yeeb nrog tshwj xeeb depability thiab kev ua tau zoo.
Peb cov kauv hlau kav hlau yog tsim los ntawm sawb hlau coils los ntawm kev siv roj hlau ob npaug arc vuam txheej txheem. Los ntawm tas mus li ntawm qhov kub tsis tu ncua molding tshuab, peb ua kom txhua lub raj yog tsim nrog qhov tseeb tshaj plaws thiab muaj xwm yeem. Qhov kev tsim kho cov txheej txheem ua kom ua tau zoo tshaj plaws kom ntseeg tau tias peb cov khoom tau raws cov qauv zoo tshaj plaws, ua rau lawv zoo rau ntau yam kev siv.

Peb cov kauv hlau kav hlau yog tsim los ntawm sawb hlau coils los ntawm kev siv roj hlau ob npaug arc vuam txheej txheem. Los ntawm tas mus li ntawm qhov kub tsis tu ncua molding tshuab, peb ua kom txhua lub raj yog tsim nrog qhov tseeb tshaj plaws thiab muaj xwm yeem. Qhov kev tsim kho cov txheej txheem ua kom ua tau zoo tshaj plaws kom ntseeg tau tias peb cov khoom tau raws cov qauv zoo tshaj plaws, ua rau lawv zoo rau ntau yam kev siv.
Piv nrog tsoos welded kav,S235 J0 KAUV STEEL YEEB Muaj cov yam ntxwv tseem ceeb hauv qab no:
A. Thaum lub sij hawm tsim qauv, cov phaj steel los ntawm kev ntxhov siab thiab muaj kev ntxhov siab tsawg. Tsis tsuas yog ua qhov no txuas ntxiv lub neej ntawm cov yeeb nkab, nws kuj ua kom pom tias cov yeeb nkab sab npoo yog cov khawb thiab tsis muaj qhov tsis zoo.
b. Peb Advanced Regerged arc vuam txheej txheem ua kom meej vuam nyob rau hauv txoj hauj lwm zoo tshaj plaws. Qhov no txo qhov tshwm sim ntawm qhov tsis xws luag xws li cov npoo tsis raug cai, vuam sib txawv, thiab tsis tiav vuam. Raws li qhov tshwm sim, peb cov kav dej tau muaj vuam zoo heev, yog qhov yooj yim los tswj thiab xyuas kom meej pem kev ua tau zoo.
C. Qhov zoo yog peb qhov tseem ceeb tshaj plaws. Yog li ntawd, peb ua txhua yam kom 100% kev tshuaj xyuas zoo rau txhua cov yeeb nkab steel steel peb tsim. Qhov kev tshuaj xyuas kev tshuaj xyuas kom peb cov kav dej tau ntsib cov qauv kev lag luam siab tshaj plaws, muab kev thaj yeeb nyab xeeb thoob plaws hauv kev tsim thiab siv cov txheej txheem.
