1. Ua ntej ua haujlwm, nws yuav tsum ua tib zoo tshawb xyuas cov xwm txheej sab hauv thiab sab nraud ntawm qhov chaw ua haujlwm. Nws yog ib qho tsim nyog yuav tsum paub seb cov tsev nyob sab nraum zoov lossis lwm cov qauv puas muaj kev cuam tshuam rau sab hauv tsev kub welding thiab txiav, thiab seb puas muaj cov khoom tawg thiab tawg hauv tsev. Yog tias tsim nyog, ua ntej Sampling thiab tsom xam cov pa roj hauv tsev, thiab lees paub kev nyab xeeb ua ntej nkag mus rau hauv kev ua haujlwm sab hauv.
2. Cov tshuab hluav taws xob Acetylene, lub tog raj kheej oxygen, thiab cov tshuab hluav taws xob tsis raug tso cai rau muab tso rau hauv chav uas kub vuam thiab txiav. Nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xyuas cov pa oxygen-acetylene pipeline thiab vuam thiab txiav lub teeb rau cov xau, thiab nruj me ntsis tiv thaiv cov pa oxygen-acetylene hauv chav tsev thiab ua rau muaj kev sib tsoo tawg. Thaum tshem tawm vuam thiab txiav, nqa cov pa oxygen-acetylene pipeline thiab vuam thiab txiav lub teeb tawm sab nraum zoov. Thiab qhib txhua lub qhov rooj, qhov rais lossis li qub, ua kom huab cua ncig ntau li ntau tau, thiab txais yuav cov cua tshuab thaum tsim nyog.
3. Thaum siv cov menyuam thav duab rau kev siv hluav taws xob vuam, vuam thiab txiav daim teb yuav tsum tau ua kom qhuav, thiab nruj me ntsis xyuas seb cov khoom siv tiv thaiv rwb thaiv tsev puas tau raws li qhov yuav tsum tau muaj kev nyab xeeb. Thaum ua hauj lwm hauv lub thawv hlau, cov welder tsis raug tso cai kov lub thawv hlau nrog lub taub hau, nraub qaum, thiab lwm yam los yog qhov chaw uas tsis muaj rwb thaiv tsev. Tag nrho cov khoom siv teeb pom kev zoo siv cov teeb pom kev tsawg-voltage.
