Kev Xav Tau Ntawm Preheating Thiab Kub Kho Ntawm Cov Khoom Tshwj Xeeb Welded Yeeb Nkab
- Cov khoom tshwj xeeb welded yeeb nkab preheating ua ntej vuam tuaj yeem tsis tsuas yog ua kom txias txias tom qab vuam, tab sis kuj pab hydrogen los ntawm vuam hlau diffusion khiav, kom tsis txhob hydrogen tawg. Nyob rau tib lub sij hawm txo cov degree ntawm hardening ntawm weld thiab tshav kub-cuam tshuam cheeb tsam, thiab txhim kho cov tawg tsis kam ntawm welded pob qij txha.
- Nws kuj tseem tuaj yeem txo qhov kev ntxhov siab ntawm kev sib tsoo, kev sib xyaw hauv zos preheating lossis tag nrho preheating, txo qhov kub ntawm qhov sib txawv ntawm cov vuam hauv cheeb tsam vuam, uas ntawm ib sab yuav txo tau qhov vuam kev nyuab siab, ntawm qhov tod tes, txo qhov vuam strain tus nqi, uas yog conducive. kom tsis txhob welding tawg. Nws tuaj yeem txo qhov kev txwv ntawm cov qauv welded, tshwj xeeb tshaj yog rau kev txo qis ntawm kev txwv ntawm lub kaum sab xis yog qhov tshwj xeeb tshaj yog pom tseeb, nrog rau qhov kub thiab txias nce, qhov tawg tshwm sim txo.
- Cov ntaub ntawv tshwj xeeb ntawm welded yeeb nkab preheating kub thiab interlayer kub xaiv tsis yog tsuas yog muaj feem xyuam rau cov tshuaj muaj pes tsawg leeg ntawm cov hlau thiab vuam pas nrig, tab sis kuj nrog lub nruj ntawm welded qauv, vuam txoj kev, ambient kub thiab thiaj li nyob. Yuav tsum tau txiav txim siab tom qab kev txiav txim siab zoo ntawm cov xwm txheej no, ntxiv rau, cov kev taw qhia ntawm lub thickness ntawm cov hlau thiab cov uniformity ntawm preheating kub nyob rau hauv lub weld cheeb tsam muaj ib tug tseem ceeb cuam tshuam rau txo vuam kev nyuaj siab.
- Thiab cov ntaub ntawv tshwj xeeb ntawm welded yeeb nkab tom qab vuam kev kho cua sov muaj peb lub hom phiaj, uas yog, kev tshem tawm hydrogen, tshem tawm cov kev ntxhov siab, txhim kho lub koom haum weld thiab kev ua tau zoo, lub luag haujlwm tseem ceeb ntawm kev kho tom qab vuam hydrogen tshem tawm yog kom ceev cov kev khiav tawm ntawm hydrogen. nyob rau hauv lub vuam thiab kub los, zoo heev tiv thaiv vuam kab nrib pleb nyob rau hauv tsawg alloy steel.
- Kev ntxhov siab kev kho cua sov yog los txo cov yield zog ntawm cov welded workpiece ntawm qhov kub thiab txias, yog li so lub vuam kev nyuaj siab, muaj ob txoj kev: ib qho yog tag nrho cov kub-kub tempering, ib lub zos high-temperature tempering. Kev kho cua sov txhim kho lub koom haum metallurgical ntawm welded pob qij txha, txhim kho cov plasticity thiab toughness ntawm welded pob qij txha, yog li txhim kho cov khoom siv kho tshuab ntawm cov pob qij txha.
- Cov saum toj no yog los qhia koj txog qhov tseem ceeb ntawm preheating ua ntej vuam thiab kev kho cua sov tom qab vuam rau cov khoom tshwj xeeb welded yeeb nkab.GNEE Group tshwj xeeb hauv kev muab cov yeeb nkab welded, uas yog tsim raws li cov khoom specification ntawm txhua lub teb chaws, thiab muaj peev xwm muab ntau yam ntawv pov thawj, txais tos koj qhov kev yuav khoom.
