Nyob rau hauv lub ntiaj teb no ntawm industrial manufacturing, tshwj xeeb tshaj yog nyob rau hauv lub zog sector, qhov zoo ntawm welds nyob rau hauv pipeline ntau lawm yog ib qho tseem ceeb heev. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cov kav xa hluav taws xob, qhov kev ncaj ncees ntawm cov vuam tuaj yeem txhais tau tias qhov sib txawv ntawm kev nyab xeeb thiab kev puas tsuaj. Ntawm peb lub Hoobkas hauv Cangzhou, Hebei Xeev, peb nkag siab txog lub luag haujlwm tseem ceeb uas cov khoom siv vuam zoo ua kom muaj kev ntseeg tau thiab kev nyab xeeb ntawm peb cov khoom. Peb lub tuam txhab tau tsim nyob rau hauv 1993 thiab tau loj hlob los npog thaj tsam ntawm 350,000 square meters, tag nrho cov cuab tam ntawm RMB 680 lab, thiab 680 cov neeg ua haujlwm siab.
Ib qho tseem ceeb uas yuav tsum tau xav txog thaum arc welding natural gas pipelines yog hom vuam tshuab ua haujlwm. Raukauv welded yeeb nkab, feem ntau txoj kev yog submerged arc vuam (SAW) txheej txheem. Cov txheej txheem no yog nyiam rau nws lub peev xwm los tsim muaj zog, ruaj khov, zoo welds. Cov txheej txheem submerged arc vuam yog tsim los ntawm ib qho arc nruab nrab ntawm cov khoom noj tsis tu ncua thiab cov khoom ua haujlwm, uas yog submerged nyob rau hauv ib txheej ntawm granular flux. Qhov no tsis tsuas yog tiv thaiv cov weld los ntawm kev sib kis, tab sis kuj txhim kho qhov zoo ntawm cov vuam los ntawm kev muab cov arc ruaj khov thiab txo qis spatter.
Qhov tseem ceeb ntawmcov kav dejwelding zoo tsis tuaj yeem overstated. Hauv kev thauj mus los ntawm cov roj av, txhua qhov vuam tsis ua haujlwm tuaj yeem ua rau muaj kev puas tsuaj loj, suav nrog kev xau, tawg thiab kev puas tsuaj ib puag ncig. Yog li ntawd, ua kom peb cov txheej txheem vuam ua tau raws li cov qauv siab tshaj plaws yog qhov tseem ceeb tshaj plaws. Peb qhov kev cog lus rau kev ua tau zoo pib nrog kev xaiv cov khoom siv raw thiab txuas ntxiv mus rau txhua theem ntawm cov txheej txheem tsim khoom, suav nrog kev sim nruj thiab tshuaj xyuas cov welds.
Ntawm peb qhov chaw Cangzhou, peb siv cov thev naus laus zis siab thiab cov kws tshaj lij los xyuas kom meej tias peb cov txheej txheem submerged arc vuam ua tau zoo. Peb pab neeg tau txais kev cob qhia ua tib zoo saib xyuas thiab tswj cov vuam tsis zoo, kom ntseeg tau tias txhua qhov vuam ua tau raws li cov kev cai nruj raws li cov qauv kev lag luam. Qhov kev mloog rau kev nthuav dav no tsis yog tsuas yog txhim kho cov qauv kev ncaj ncees ntawm peb cov kav dej, tab sis kuj tau txais kev ntseeg siab ntawm peb cov neeg siv khoom, uas tso siab rau peb cov khoom kom muaj kev nyab xeeb thiab muaj txiaj ntsig kev thauj mus los.
Tsis tas li ntawd, cov raj xa dej vuam zoo ncaj qha cuam tshuam rau tag nrho kev ua haujlwm thiab lub neej ntawm cov kav dej. Siab zoocev weldtxo qhov kev pheej hmoo ntawm kev saib xyuas cov teeb meem thiab txuas ntxiv lub neej ntawm cov kav dej, thaum kawg txuag cov nqi rau peb cov neeg siv khoom. Nyob rau hauv ib qho kev lag luam uas kev ntseeg siab yog qhov tseem ceeb, kev nqis peev hauv qhov zoo tshaj plaws weld yog ntau tshaj qhov kev xaiv; nws yog qhov tsim nyog.
Hauv kev xaus, qhov tseem ceeb ntawm cov kav dej vuam zoo hauv kev tsim cov raj xa hluav taws xob tsis tuaj yeem tsis quav ntsej. Raws li cov chaw tsim khoom lag luam, peb txoj kev mob siab rau kev siv cov thev naus laus zis thev naus laus zis xws li submerged arc welding thiab peb tsom rau kev tswj kom zoo ua rau peb muaj kev ntseeg siab rau peb cov neeg siv khoom. Nrog ntau tshaj peb lub xyoo dhau los ntawm kev paub dhau los thiab cov neeg ua haujlwm rau siab, peb tseem ua qhov tseem ceeb ntawm kev nyab xeeb thiab kev ntseeg siab ntawm peb cov khoom, kom ntseeg tau tias peb ua tau raws li cov kev xav tau ntawm kev lag luam hluav taws xob hloov zuj zus. Raws li peb mus tom ntej, peb nyob ruaj khov nyob rau hauv peb lub luag hauj lwm los muab cov zoo tshaj plaws natural gas pipelines, vim hais tias thaum nws los txog rau lub zog kev thauj mus los, zoo tsis yog tsuas yog ib qho tseem ceeb; nws yog qhov tseem ceeb.
