1.Yuav ua li cas vuam txoj kev yog feem ntau siv rau Q195 welded kav?
Cov txheej txheem vuam siv rau Q195 welded kav muaj xws li hluav taws xob tsis kam vuam (ERW), roj hlau arc vuam (GMAW), thiab submerged arc vuam (SAW). ERW yog qhov siv dav tshaj plaws vim nws qhov ua tau zoo thiab tus nqi qis, tsim nyog rau cov kav dej me me mus rau nruab nrab txoj kab uas hla.
2. Txoj kev vuam zoo li cas rau Q215 welded kav?
Q215 welded kav yuav welded los ntawm ERW, GMAW, SAW, thiab phau ntawv hlau arc vuam (MMAW). Rau qhov loj -inch thiab tuab-walled Q215 welded kav, SAW yog qhov zoo dua rau nws qhov ruaj khov vuam zoo thiab ua haujlwm siab.
3. Txoj kev vuam twg zoo tshaj plaws rau Q235 welded kav?
Q235 welded kav yog sib xws nrog ntau yam vuam txoj kev, xws li ERW, GMAW, SAW, thiab MMAW. ERW yog siv rau tej yam nyias nyias- cov kav dej, thaum SAW yog tsim rau tuab - cov kav dej uas siv rau hauv siab - siab lossis hnyav - chaw thau khoom, ua kom muaj zog vuam txaus.
4. Dab tsi yog qhov txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm Q195 thiab Q235 steels?
Qhov sib txawv tseem ceeb yog nyob rau hauv cov ntsiab lus carbon thiab manganese cov ntsiab lus. Q195 muaj cov ntsiab lus qis dua (tsawg dua lossis sib npaug li 0.12%) thiab cov ntsiab lus manganese (0.25-0.50%), thaum Q235 muaj cov ntsiab lus carbon ntau dua (0.14-0.22%) thiab cov ntsiab lus manganese (0.30-0.65%). Qhov siab dua carbon thiab manganese cov ntsiab lus ntawm Q235 muab nws zoo dua txhua yam muaj zog.
5. Lub zog tensile ntawm Q195, Q215, thiab Q235 welded kav sib piv li cas?
Lub zog tensile ntawm Q195 welded kav yog 315-430 MPa; Q215 welded kav muaj lub zog tensile ntawm 335-450 MPa; Q235 welded kav muaj lub zog tensile siab tshaj plaws, xws li 375-500 MPa. Lub zog tensile nce nrog kev nce qib ntawm tus lej.
