Tswj los ntawm tsib yam: tib neeg, khoom siv, tshuab, txoj cai, thiab nplhaib.
① Tib neeg yam tseem ceeb yog qhov tseem ceeb ntawm kev tswj vuam. Yog li ntawd, ua ntej welding, welders uas txawj thiab welded yuav tsum raug xaiv los ua qhov tsim nyog kev cob qhia thiab configuration. Nws tsis raug tso cai los hloov nws ntawm qhov xav tau los xyuas kom meej tias cov welding yeeb nkab welding yog qhov ruaj khov.
② Tswj cov khoom siv vuam: xyuas kom meej tias cov khoom siv welded ntawm cov khoom siv tsis tu ncua raug yuav, nrog cov ntawv pov thawj thiab daim ntawv pov thawj tsim nyog, uas ua tau raws li cov txheej txheem; kev tswj nruj ntawm qhov thaiv kom ntseeg tau qhov ntws thiab qhov nyiaj; Kev faib tawm tsis pub dhau ib nrab hnub.
③ Vuam tshuab: Lub tshuab vuam yuav tsum ua kom ntseeg tau kev ua tau zoo thiab ua tau raws li qhov xav tau ntawm cov txheej txheem; lub tshuab vuam yuav tsum muaj qhov tsim nyog tam sim no thiab ntsuas qhov ntsuas hluav taws xob kom ntseeg tau tias qhov tseeb ntawm cov txheej txheem vuam. Vuam cables yuav tsum tsis txhob ntev dhau, thiab vuam tsis yuav tsum tau kho kom ntev.
④ Vuam txheej txheem txheej txheem: xyuas kom nruj kev siv cov txheej txheem tshwj xeeb ntawm cov kav dej galvanizing, cov txheej txheem vuam raug tshuaj xyuas ua ntej vuam, cov txheej txheem vuam tsis raug, cov txheej txheem kev ua haujlwm, thiab kev soj ntsuam zoo tom qab vuam. Tswj tus nqi ntawm cov khoom siv welded ntawm qib vuam thiab tus nqi ntawm cov welded hauv txhua lub qhov ncauj.
⑤ Welding ib puag ncig tswj: xyuas kom qhov kub, av noo, thiab cua ceev thaum vuam ua tau raws li cov txheej txheem.
