Cov Khoom Siv Yeeb Nkab ERW Yuav Tsis Qhia Koj Li Cas: Yuav Tsum Nug Cov Lus Nug Ua Ntej Yuav Khoom

Thaum yuav cov yeeb nkab welded, cov chaw tsim khoom feem ntau hais txog lub peev xwm tsim khoom thiab tus nqi, tab sis cov teeb meem tseem ceeb hauv qab no yooj yim tsis quav ntsej:

1. Kev ruaj khov ntawm cov khoom tseem ceeb (piv txwv li, kev tsim cov yob, cov tshuab vuam zaus siab)?

Lub tshuab yeeb nkab welded uas pheej yig yuav siv cov hlau tsis zoo, ua rau dov hnav sai thiab cov nqi hloov pauv siab.

2. Cov nqi siv hluav taws xob thiab kev saib xyuas yog dab tsi?

3. Kev txhawb nqa kev siv tshuab thiab kev pabcuam tom qab muag teb tau sai npaum li cas?

Qee lub chaw tsim khoom siv yeeb nkab vuam muaj cov lus teb qeeb tom qab muag, nrog rau kev kho yuav siv sijhawm ntau lub lis piam, uas cuam tshuam loj heev rau cov sijhawm tsim khoom.

4. Puas yog nws txhawb nqa kev tsim khoom tshwj xeeb?

Yog tias tsim cov kav dej lossis cov ntaub ntawv zoo li tshwj xeeb (piv txwv li, hlau tsis xeb), xyuas seb cov khoom siv yeeb nkab vuam puas tuaj yeem ua raws li cov txheej txheem hloov kho uas xav tau.

Mus saib cov chaw tsim khoom cov neeg siv khoom rau kev tshuaj xyuas ntawm qhov chaw kom tsis txhob muaj kev pheej hmoo xaiv vim yog cov ntaub ntawv tsis sib xws.
