6g Vuam cov qib ntawm cov kev sib tw uas muaj kev sib tw tshaj plaws hauv kev lag luam, xav tau ib qho kev sib txuas ntawm lub cev, thiab kev txiav txim siab thib ob-} ua. Nws cov teeb tsa stems los ntawm qhov ruaj 45 {- Scritting rau kev hloov pauv kev sib tsoo thiab kev sib koom tes uas tau hais tseg txawm tias cov kws tshaj lij lom zem.
Ntawm nws cov tub ntxhais, qhov 45 {{{4 4}}}}}}}}}}}}}} Cov peev xwm tig qhov chaw ua haujlwm, ib qho khoom kim heev nyob hauv cov haujlwm yooj yim xws li 1g lossis 2g. Welders yuav tsum tswj lawv cov cuab yeej nyob ib ncig ntawm cov yeeb nkab nruab ncig, hloov chaw los ntawm ze-tiaj tus txiv ntoo kom muaj kev ncua. Qhov kev hloov no cuam tshuam rau lub pob zeb molten lub stability: kev pheej hmoo ntawm kev sib koom tes, nws tuaj yeem ua tsis tiav kev tsim kho, ua rau undercutting lossis tawg. Kev tswj hwm cov hlaws dai uas yuav tsum muaj qhov tsis zoo rau cov kev tawm suab sov thiab cov txuj ci siab tsuas yog los ntawm ntau lub sijhawm xyaum.
Lub cev hu rau kev sib tw. Welders feem ntau sib cav txog lawv lub cev kom ncav cuag txhua sab ntawm cov yeeb nkab, tuav txoj haujlwm txawv txawv thaum hnav hnyav tiv thaiv hnyav tiv thaiv. Qaus creeps hauv kev ruaj khov sai, tsis txaus ntseeg tes- qhov tsis txaus ntseeg thaum txawm tias 1-millimeter txawv tuaj yeem ua rau lub weld. Kev tsom xam ntau yuav tsum tau saib xyuas lub arc ntev, taug kev nrawm, thiab txo qis ntxiv ib zaug kev xav hauv lub siab lub ntsws
Cov ntawv pov thawj qauv underscore 6g's Rigor. Kev hla dhau yuav tsum tau Welds dawb ntawm kev tsis xws luag, suav nrog, txhawm rau kev ntsuas nruj xws li radeCegraphy lossis Ultrasonic tshuaj ntsuam. Tsis zoo li yooj yim txoj haujlwm uas qhov tsis txaus ntshai yuav khiav tawm daim ntawv ceeb toom, 6g tiv taus tsis muaj qhov yuam kev; Ib qho pinhole ib qho hauv qhov tseem ceeb tshaj plaws tuaj yeem tsis tau txais kev sim tag nrho. No xoom - npoo ib puag ncig ntxiv kev puas siab, nrog ntau tus neeg welders qhia txog kev sim siab thaum muaj ntawv pov thawj.
Cov khoom siv hloov pauv qhov nyuaj. Ua haujlwm nrog tuab -} {{-}}} alloy}}} alloy}}} allloceters rau cov ntaub ntawv nrog sib txawv thermal condal conductivity. Txhua cov khoom siv xav tau ib qho kev xav tau ib qho kev xav tau, xav tau cov welders kom nco thiab hloov kho kom haum rau ntau yam kev sib tw {}} kev paub uas siv sijhawm ntau xyoo los khaws cia.
Kev lag luam cov ntaub ntawv qhia txog kev kawm ntxhab ntxhab nkhaus. Lub chaw tshawb fawb 2025 los ntawm National Center for Vuam kev pom tias tsuas yog 15% ntawm welders nrog tsib xyoos ntawv pov thawj ntawm lawv thawj zaug. Txawm nyob ntawm cov uas muaj ib xyoo caum hauv daim teb, tus ntaus nqi dhau mus ncig 40%. Ntau daim ntawv qhia ntau yam ua tsis tau tejyam, txhua cov sijhawm npaj thiab siv tau cov khoom siv.
Tsis tau, qhov nyuaj tsis yog insurmountable. Mastery los ntawm tawg cov txheej txheem rau cov ntu tswj hwm: kev hloov pauv ntawm cov ces kaum, ua kom muaj kev tswj hwm kub thiab kev tsim kho cov leeg nqaij rau hluav taws xob. Cov cuab yeej qhia niaj hnub no, xws li kev kawm Weld Simulators, pab ua kom cov khoom siv tsis muaj cov khoom siv tsis zoo ntawm cov tswv yim arc tiag.
Thaum kawg, 6g vuam qhov nyuaj yog nws lub ntsiab lus txhais tau. Nws cais cov kws tshaj lij ntawm cov neeg thoob pheej, ua haujlwm raws li kev ua tau zoo tshaj plaws hauv kev lag luam uas Weld kev ncaj ncees yog tsis yog dab tsi. Rau cov neeg uas kov yeej nws, qhov kev sib tw ua ib qho kev khav theeb- Lub tswv yim xav tau rau ib qho ntawm cov khoom siv tes ua lag luam tshaj plaws hauv kev tsim khoom.
