Cov qauv thiab cov khoom ntawm weld thiab niam txiv cov khoom ntawm kub-dov welded steel-ntxig rau cov tshuab hniav
Tom qab kub-dov welded steel-ntxig yog cua sov-kho, cov hniav hlau thiab hniav lub cev yog xim sib xyaw ua ke; Microtertructure ntawm alloy steel hniav steel yog kho kom zoo thiab hnav khaub ncaws zoo, uas tau lees paub los ntawm cov txheej txheem kho cua sov zoo tshaj plaws; Lub microstructure ntawm Q235 steel hniav lub cev yog qhov nyuaj, uas yog cuam tshuam nrog cov txheej txheem kub-muab tso rau thiab cov txheej txheem kev kho cua sov. Lub zog shear ntawm Weld feem ntau yog 196-343 MPa, thiab cov pa roj didusion txheej ntawm weld sib sib zog nqus. Tus yuam sij los txhim kho chav Weld lub zog yog txhawm rau txo cov kev suav thiab porosity ntawm weld kab. Raws li kev tsom xam ntawm kub-dov vuam mechanism, nws ntseeg tau tias nce qhov kub thiab txias kom muaj txiaj ntsig zoo rau cov khoom seem vuam ntawm cov sib koom ua ke. Tsim nyog qhov kub thiab dov tsis yog qhov yuav tsum tau ua kom tau microstructure zoo heev, tab sis kuj yuav tsum tau txo kev siv hluav taws xob thiab dov lub zog.
