Lub ntsiab yog vim li cas rau demagnetization ntawm kauv welded kav - tshem tawm tej zaum yuav muaj kev phom sij

Hauv qee qhov chaw tshwj xeeb, xws li thaj chaw uas muaj cov hlau nplaum muaj zog lossis cov xwm txheej uas xav tau kev ntsuas siab, cov hlau nplaum seem yuav ua rau muaj kev phom sij txaus ntshai lossis ntsuas qhov yuam kev. Piv txwv li, nyob rau hauv cov cheeb tsam uas muaj siab concentration ntawm cov khoom siv hluav taws xob, qhov seem hlau nplaum yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv no. Hauv cov xwm txheej uas yuav tsum tau ntsuas qhov tseeb, cov hlau nplaum seem yuav ua rau muaj qhov sib txawv ntawm qhov ntsuas ntsuas. Yog li ntawd, txhawm rau txhawm rau tshem tawm cov teeb meem kev nyab xeeb thiab ntsuas qhov yuam kev, kev kho demagnetization yog qhov tsim nyog rau cov kav welded steel kav.
