Q: Dab tsi yog hom vuam electrode feem ntau siv rau Q235?
A: E43 series (piv txwv li, E4303). Rau cov qauv tseem ceeb, E4315 / E4316 yooj yim vuam electrodes muab kev tiv thaiv zoo dua.
Q: Yuav ua li cas tiv thaiv porosity thaum vuam Q235?
A: Qhuav lub vuam electrodes, ntxuav cov roj thiab xeb, tswj cov purity ntawm shielding gas, thiab siv cov vuam tsis tsim nyog.
Q: Puas yuav tsum tau preheating rau Q235 vuam?
A: Rau cov phaj tsawg dua lossis sib npaug ntawm 40mm tuab, feem ntau tsis tas yuav tsum tau preheating ntawm chav tsev kub; rau cov phaj tuab lossis qis- qhov kub thiab txias, preheat rau 100-150℃kom tsis txhob muaj qhov txias txias.
Q: Dab tsi yog qhov txias dabtsi yog khoov ntawm Q235?
A: Cov khoom txias txias zoo, haum rau txias stamping thiab txias bending ntawm steel seem (xws li lub kaum sab xis steel thiab channel steel).
Q: Q235 puas tuaj yeem ua cua sov- kho kom muaj zog?
A: Tsawg- carbon steel tsis muaj zog hardenability, thiab tempering nyhuv yog txwv; Kev kho cua sov feem ntau tsis tas yuav tsum tau ua. Rau kev hnav tsis kam, nto carburizing / quenching tuaj yeem ua.
