Dab tsi yog cov yam ntxwv ntawm kev ua haujlwm txias ntawm Q195 steel phaj?
Nws muaj plasticity zoo thiab tuaj yeem raug stamped, khoov, thiab sheared. Tom qab txias ua hauj lwm hardening, nws lub zog nce tab sis nws toughness txo, yog li tus nqi ntawm deformation thaum lub sij hawm ua yuav tsum tau tswj.
Dab tsi yog txoj kev vuam rau Q195 steel phaj?
Nws yog sib xws nrog shielded hlau arc vuam (SMAW), CO₂ gas shielded vuam, thiab argon arc vuam (argon arc vuam). Nws muaj qhov zoo tshaj plaws weldability thiab tsis yooj yim rau tawg.
Dab tsi welding rods / hlau yuav tsum tau siv rau vuam Q195 steel phaj?
E4303 (J422) vuam pas nrig thiab ER50-6 vuam hlau yuav tsum raug xaiv kom phim lawv cov yam ntxwv ntawm cov pa roj carbon tsawg thiab xyuas kom muaj kev ua tau zoo ntawm cov vuam sib txuas.
Puas yog preheating lossis post- cua sov yuav tsum tau rau vuam Q195 steel phaj?
Tsis xav tau preheating ntawm chav tsev kub. Rau cov phaj tuab dua 12 hli los yog rau qis - qhov kub thiab txias (tsawg dua los yog sib npaug rau -5 degree), preheating rau 50-100℃yog tsim nyog los tiv thaiv kom txhob txias tawg.
Dab tsi yog qhov tseem ceeb ntawm kev sib tsoo ntawm Q195 steel phaj? Hlav-los ntawm (hauv nyias daim hlau) thiab qhov porosity yuav tshwm sim, yog li cov vuam tam sim no yuav tsum tau tswj (tsawg dua lossis sib npaug li 160A) thiab siv cov txheej txheem arc luv luv.
