Magnetic flaw detection tsuas nrhiav tau qhov nto thiab nyob ze ntawm qhov ntom nti Q235B welded yeeb nkab, thiab nws tsuas ua tau qhov ntsuam xyuas ntau rau cov tsis xws luag.Qhov qhov thiab qhov tob ntawm qhov tsis xws luag, nws tsuas yog xam tau raws li kev paub xwb. nrhiav cov kev tsis haum los ntawm kev siv xau ntawm hlau nplaum, uas yog ua los ntawm magnetic field magnetization Q235B welded yeeb nkab.Raws li txoj kev sib txawv ntawm kev nqeses ntawm kev sib nqus, nws muab faib ua hlau nplaum, txoj kev nqus hlau nqus hlau thiab cov ntaubntawv povthawj txoj kev, nyob rau hauv uas feem ntau dav siv sib nqus hmoov txujci.
