Welded yeeb nkab deg quenching thiab tempering tshav kub kho yog feem ntau yog ua los ntawm induction cua sov los yog
taws cua sov. Lub ntsiab technical tsis yog teeb meem ntawm sab nraud, lub zos hardness thiab ua kom muaj zog
txheej qhov tob. Hardness kuaj siv Vickers hardness tester, kuj siv Rockwell los yog Rockwell nto
hardness. Qhov kev xaiv ntawm kev sib tw (nplai) muaj feem xyuam rau qhov tob ntawm qhov sib zog ntawm cov tawv thiab txheej txheem
hardness ntawm welded yeeb nkab. Ntawm no yog peb qhov nyuaj.
