Vuam pas nrig lossis electrodes tuaj yeem muaj ntau yam khoom siv uas tuaj yeem ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv yog tias tsis muaj kev ceev faj thaum siv. Lub toxicity ntawm vuam pas nrig yog nyob ntawm qhov muaj pes tsawg leeg ntawm tus pas nrig thiab cov pa taws uas tsim thaum lub sij hawm vuam.
Qee cov welding rods muaj cov ntaub ntawv xws li manganese, chromium, npib tsib xee, thiab cadmium, uas tuaj yeem ua rau muaj kuab lom thaum nqus tau siab. Thaum cov ntaub ntawv no raug cua sov thaum vuam, lawv tuaj yeem tso pa tawm uas tuaj yeem ua rau muaj kev phom sij yog tias nqus tau. Tsis tas li ntawd, cov txheej ntawm cov welding rods tuaj yeem muaj cov tshuaj uas tsim kev puas tsuaj yog tias noj los yog nqus tau.
Txhawm rau txo qis cov kev phom sij rau kev noj qab haus huv cuam tshuam nrog cov welding rods, nws yog ib qho tseem ceeb uas yuav tsum ua raws li kev ntsuas kev nyab xeeb tsim nyog, xws li siv qhov cua kom zoo, hnav khaub ncaws tiv thaiv, thiab siv kev tiv thaiv ua pa. Vuam nyob rau hauv qhov chaw muaj cua zoo tuaj yeem pab txo qis cov pa taws hauv huab cua, thaum hnav cov khoom tiv thaiv tus kheej, xws li hnab looj tes, aprons, thiab lub tshuab ua pa, tuaj yeem pab tiv thaiv kom tsis txhob raug cov khoom phom sij.
Hauv cov ntsiab lus, thaum vuam rods tuaj yeem ua rau muaj kev phom sij yog tias tsis siv kom raug, ua raws li kev ntsuas kev nyab xeeb tsim nyog tuaj yeem txo qhov kev pheej hmoo cuam tshuam nrog vuam.
