Rau nruab nrab tuab phab ntsa, ntev ntev workpieces, thiab workpieces welded nyob rau hauv ib tug muaj zog magnetic teb ib puag ncig, magnetic bias tshuab yuav tshwm sim thaum lub vuam txheej txheem. Qhov tshwm sim no feem ntau tshwm sim, thiab qhov teeb meem nws ua rau tsis tuaj yeem kwv yees, tshwj xeeb tshaj yog rau cov haujlwm ntev ntev. Ib qho yuam kev me me feem ntau ua rau kev puas tsuaj rau tag nrho cov khoom ua haujlwm.
Yog li dab tsi yog qhov phom sij ntawm welding magnetic bias tshuab?
Vuam magnetic bias tshuab tuaj yeem ua rau tsis sib xws ntawm cov hlaws weld thiab tsis zoo weld tsim, cuam tshuam rau vuam zoo.
Qhov laj thawj tseem ceeb rau qhov tshwm sim no yog kev siv DC arc vuam.
Nws kuj yog ib qho yooj yim los daws qhov teeb meem no los ntawm kev siv AC vuam tshuab. Txawm li cas los xij, rau kev ua haujlwm qhov chaw ua haujlwm loj dhau thiab qhov teeb meem ntawm qhov chaw vuam yog qhov nyuaj, nws yuav nyuaj rau kev siv cov txheej txheem AC vuam. Yog li ntawd, lub zos demagnetization thiab magnetic shielding yog txoj kev zoo.
