Kev siv vuam vias yog kev tshawb fawb uas tuaj yeem kawm hauv cov chav kawm tshwj xeeb lossis hauv tsev kawm ua haujlwm txheej txheem. Tab sis txawm hais tias kev txawj ntse txuj ci tsis ib txwm pab cuam tam sim ntawd cov hau kev ntawm kev ua zoo txuas. Nrog kev xyaum, kev paub tau ntxiv, thiab cov haujlwm ntawm vuam ua haujlwm nce siab.

Cov Lus Qhia
Kauj ruam 1
Nws tsis pom zoo siv roj vuam yam tsis muaj kev paub tshwj xeeb. Qhov piv tsis yog ntawm acetylene thiab oxygen tso rau hauv cov thawv iav tuaj yeem ua rau tawg thiab raug mob. Yog li ntawd, ib qho tuaj yeem npaj ncaj qha mus rau kev xyaum tsuas yog tom qab kev qhia theoretical kev kawm ua kev taw qhia los ntawm cov kws paub tshwj xeeb.
Kauj ruam 2
Hauv cov kev kawm tshwj xeeb, koj yuav tau qhia cov kev kawm vuam niaj hnub, qhia kom paub ntsuas cov teeb tsa kom raug, xaiv lub teeb, thiab ua kom koj paub txog kev tiv thaiv kev nyab xeeb thiab vuam cov cai.
Kauj ruam 3
Tom qab tau txais koj daim ntawv pov thawj ntawm cov pa welder, npaj mus xyaum. Siv cov kev tshawb xav, tab sis tsis txhob hnov qab tias koj yuav kawm ua noj tsuas yog tias koj tau ua haujlwm hauv qhov kev paub txaus ntawm qhov kev paub zoo.
Kauj ruam 4
Yuav cov roj a tuaj yeem, welder lub ce, lub npog ntsej muag, taws teeb nrog 4 txheej. Kawm kom paub tsim kev kub siab nyob rau hauv hoses ntawm lub cuab yeej. Raws li txoj cai, cov pa oxygen siab yuav tsum tsis txhob siab tshaj 0.3 MPa, qhov tso tshuaj acetylene siab rau hauv reducer yuav tsum tsis txhob qis dua 1 kPa. Siv tsuas yog chav kawm thib peb oxygen oxygen rau vuam, tsis txhob siv cov hoses sib txuas rau lwm yam.
Kauj ruam 5
Siv lub qhov cub ntawm ntau lub ces kaum, tso txoj kev kawm rau kev xyaum. Tsis txhob saib xyuas kev tiv thaiv kev nyab xeeb. Txhua zaus yuav tsum yog tus kav hlau tiv thaiv kev tiv thaiv, hnab looj tes, hnab looj tes, thiab ib lub kaus mom hlau lossis lub kaus mom hnyav.
Kauj Ruam 6
Ua ntej, kawm los txuas weld ntxhib rau ntawm cov hlau tuab. Raws li koj tau paub txog txheej txheem vuam, pib vuam thinner hlau siv qhov taw qhia me me. Kev coj ua txhua hnub yuav pab koj sai sai ntawm cov txuj ci kev tsim nyog uas tuaj yeem ua rau koj muaj peev xwm ua tiav txoj haujlwm nyuaj.
