Q235 weldability?
A: Weldability zoo heev, cov ntsiab lus carbon tsawg, feem ntau tsis muaj preheating yuav tsum tau, haum rau phau ntawv arc vuam, submerged arc vuam, thiab roj shielded vuam.
Dab tsi yog qhov feem ntau siv vuam electrodes rau Q235 vuam?
A: E43 series (xws li E4303, E4315), sib piv Q235 lub zog qib.
Puas yog Q235 vuam xav tau preheating?
A: Rau thicknesses ≤30mm, tsis tas yuav tsum tau preheating ntawm chav tsev kub; rau cov phaj tuab / qis- qhov kub thiab txias, preheat rau 100-150℃.
Q235 thiab Q355 puas tuaj yeem welded ua ke?
A: Yog, siv E50 series vuam electrodes, tswj cov txheej txheem raws li Q355 yuav tsum.
Puas yog Q235 vuam xav tau kev kho cua sov tom qab vuam?
A: Feem ntau, tsis muaj kev kho cua sov yuav tsum tau tom qab vuam rau cov qauv siv; rau cov phaj tuab / cov qauv dynamically loaded, kev ntxhov siab -relief annealing (600-650 degree) raug pom zoo.
