Weld kab yog feem ntau ntawm ntau yam tsis xws luagtxhaj tshuaj molded khoom.Tsuas yog qee qhov kev txhaj tshuaj molded qhov chaw nrog cov duab geometric yooj yim heev, cov kab txuas tau tshwm sim ntawm feem ntau ntawm kev txhaj tshuaj molded qhov chaw (feem ntau yog nyob rau hauv cov duab ntawm kab los yog V-shaped zawj), tshwj xeeb tshaj yog rau cov khoom loj thiab cov khoom uas yuav tsum tau siv ntau lub rooj vag pwm. thiab inserts.
Cov kab weld tsis tsuas yog cuam tshuam rau qhov zoo ntawm cov khoom yas, tab sis kuj cuam tshuam rau cov khoom siv ntawm cov khoom yas, xws li kev cuam tshuam lub zog, tensile lub zog, elongation ntawm kev tawg, thiab lwm yam. Tsis tas li ntawd, cov kab weld kuj muaj kev cuam tshuam loj heev rau cov khoom siv. cov khoom tsim thiab lub neej ntawm cov khoom yas.Yog li ntawd, nws yuav tsum tau zam los yog txhim kho kom ntau li ntau tau.
Cov laj thawj tseem ceeb ntawm txoj kab vuam yog: thaum cov yas molten ua tau raws li qhov ntxig, qhov, thaj chaw uas tsis muaj qhov txaus txaus los yog cheeb tsam nrog cuam tshuam cov khoom ntim hauv cov pwm kab noj hniav, ntau yam melts converge;Thaum lub qhov rooj txhaj tshuaj filling tshwm sim, cov ntaub ntawv tsis tuaj yeem raug fused tag nrho.
(1) Kub qis heev
Lub shunting thiab converging zog ntawm cov khoom uas tsis kub molten yog tsis zoo, thiab cov weld kab yog yooj yim rau tsim.Yog hais tias sab hauv thiab sab nraud ntawm cov khoom yas muaj vuam kab zoo ntawm tib txoj hauj lwm, nws feem ntau yog vim tsis zoo vuam los ntawm cov khoom siv kub tsawg.Hauv qhov no, qhov kub ntawm lub thoob thiab lub nozzle tuaj yeem tsim nyog nce lossis lub voj voog txhaj tshuaj tuaj yeem txuas ntxiv kom nce cov khoom kub.Nyob rau tib lub sijhawm, tus nqi ntawm cov dej txias dhau los ntawm cov pwm yuav tsum tau tswj, thiab pwm kub yuav tsum tau nce kom tsim nyog.
(2)Pwmqhov tsis xws luag
Cov qauv tsis sib xws ntawm cov pwm gating system muaj kev cuam tshuam zoo rau fusion ntawm flux, vim tias qhov tsis zoo fusion feem ntau yog tshwm sim los ntawm shunt thiab confluence ntawm flux.Yog li ntawd, lub rooj vag hom uas muaj kev hloov pauv tsawg dua yuav tsum tau txais kom deb li deb tau thiab lub rooj vag txoj haujlwm yuav tsum raug xaiv kom tsim nyog kom tsis txhob muaj qhov tsis sib xws thiab cuam tshuam ntawm cov khoom siv ntws.Yog tias ua tau, ib lub rooj vag taw tes yuav tsum raug xaiv, vim tias lub rooj vag no tsis tsim ntau cov kwj ntawm cov khoom ntws, thiab cov ntaub ntawv molten yuav tsis converge los ntawm ob qho kev qhia, yog li nws yog ib qho yooj yim kom tsis txhob weld kab.
(3) Cov pwm tsis zoo
Thaum lub fusion kab ntawm cov khoom melted coincides nrog pwm kaw kab los yog caulking, cov huab cua uas tau tsav los ntawm ntau kwj ntawm cov khoom nyob rau hauv pwm kab noj hniav yuav raug tso tawm los ntawm cov pwm kaw qhov sib txawv los yog caulking;Txawm li cas los xij, thaum cov kab vuam tsis sib haum nrog cov pwm kaw kab los yog caulking, thiab lub qhov cua qhov tsis raug teeb tsa kom zoo, cov cua seem hauv cov pwm kab noj hniav uas tau tsav los ntawm cov khoom ntws tsis tuaj yeem tso tawm.Lub npuas yog yuam kom nyob rau hauv siab, thiab lub ntim maj mam txo, thiab thaum kawg compressed rau hauv ib tug taw tes.Vim tias lub zog molecular dynamic zog ntawm cov cua compressed hloov mus rau hauv lub zog hluav taws xob nyob rau hauv kev kub siab, qhov kub ntawm cov khoom molten sau taw tes nce.Thaum nws qhov kub thiab txias yog sib npaug los yog me ntsis siab dua qhov kub decomposition ntawm raw khoom, Daj dots yuav tshwm sim ntawm lub melting point.Yog tias qhov kub thiab txias ntau dua li qhov kub ntawm cov khoom siv raw, cov dots dub yuav tshwm sim ntawm qhov melting point.
(4) Kev siv tsis raug ntawm kev tso tawm tus neeg sawv cev
Kev tso tawm ntau dhau los lossis hom tsis raug yuav ua rau cov kab txuas ntawm cov khoom yas.Hauv kev txhaj tshuaj molding, ib qho me me ntawm tus neeg tso tawm feem ntau siv sib npaug nkaus xwb rau qhov chaw uas tsis yooj yim rau demould, xws li xov.Hauv txoj ntsiab cai, tus nqi tso tawm yuav tsum raug txo kom ntau li ntau tau.
