1. Xaiv cov hnab looj tes vuam raws li koj qhov chaw ua haujlwm. Piv txwv, cov welders xav tau tuab dua thiab ntev dua cov hnab looj tes vuam. Thickness tuaj yeem tiv thaiv lawv cov tes los ntawm kev kub hnyiab, thiab ntev ntev tuaj yeem tiv thaiv lawv cov caj npab kom raug mob.
2. Raws li koj xaiv kev ua haujlwm, piv txwv li, argon arc vuam yog qhov ib leeg ua haujlwm, feem ntau yog ua haujlwm sab xis, tab sis argon arc vuam hnab looj tes tsis tas yuav tuab heev, tab sis lawv yuav tsum ua kom ntev.
3. Raws li kev xaiv ntawm lub caij, feem ntau lub hnab looj tes vuam siv nyob rau lub caij ntuj sov tsis dhau tuab, uas yuav hnov cov kub thiab ua haujlwm tsis txaus ntseeg;
Txuj Lag Luam:
Cov hnab looj tes tes xuas tes ua ntev dua 35cm nyob ntev thiab muaj qee yam ntawm kev ua haujlwm rwb thaiv tsev. Qhov txuas ntawm hnab looj tes yuav tsum tsis raug tawm. Cov cua sov rwb thaiv tsev yog siab dua 100 degrees Celsius, thaum ua kom dexterity thiab kev nplij siab yuav tsum txiav txim siab.
Cov hnab looj tes loj TIG muaj qhov ntev dua 25cm hauv qhov ntev thiab muaj qee yam khoom rwb thaiv tsev. Cov tawv yog mos thiab qhov loj me yuav tsum tsim nyog.
Kev tiv thaiv kev ua tau zoo: kev tiv thaiv thaum tshav kub kub, hluav taws kub thiab nplaim taws nplaim taws, thaiv cov hlau sib tsoo, tiv thaiv hluav taws xob, rwb thaiv tsev, tiv thaiv hnav, tiv thaiv txiav thiab tiv thaiv.
Muaj kev nyab xeeb zoo: haum loj, haum haum, yooj yim kom nqus hws.
Kev ua tau zoo: hnav tsis kam, siab tensile quab yuam, tsim kua muag tsis kam, siab kub tiv thaiv, ntxiv dag zog ntawm qhov chaw nyuab siab, kab hluav taws
Cov khoom siv: Cov khoom siv chromium (VI), PCP keeb tsis dhau tus qauv, thiab PH tus nqi yog tsim nyog.
