Lub hauv paus ntsiab lus ua haujlwm thiab daim ntawv thov kev sib txhuam welding
Hauv kev tsim khoom siv tshuab, nws yog ib qho ua rau cov hlau qhov chaw ntawm cov khoom ua haujlwm los ua ke thiab sib txuas ua ke vim yog cov cua sov tsim los ntawm kev sib txhuam, xws li thaum tig workpieces ntawm cov cuab yeej siv tshuab. Los ntawm kev txheeb xyuas ntawm cov adhesion thiab vuam phenomena, lub ntsiab ntawm kev sib txhuam vuam tuaj yeem nkag siab. Kev sib txhuam vuam yog ib txoj kev vuam uas siv cov kev sib txhuam ntawm cov cua sov thiab cov yas deformation los ntawm kev sib txhuam ntawm qhov chaw ua haujlwm kom nce qhov kub ntawm qhov sib txuas mus rau qhov kub thiab txias nyob ze tab sis hauv qab lub melting point, ua rau lub workpiece mus rau yas deformation. thiab ntws hauv siab. Qhov no yog ua tiav los ntawm diffusion thiab recrystallization ntawm interface molecules.
Muaj ntau txoj hauv kev ntawm kev sib txhuam vuam, thiab raws li qhov kev sib txhuam ntawm kev sib txhuam thiab cov txheej txheem cov yam ntxwv, ib qho ntawm cov khoom siv tiag tiag muaj xws li kev sib txhuam txhuam vuam, lub zog cia kev sib txhuam vuam, theem tswj kev sib txhuam vuam, inertia kev sib txhuam vuam, kev sib txhuam vuam, thiab do kev sib txhuam welding. Ntawm lawv, nruam tsav kev sib txhuam vuam, theem tswj kev sib txhuam vuam, inertial kev sib txhuam vuam, thiab kev sib txhuam kev sib tsoo vuam vam khom kev sib txhuam kev sib txhuam ntawm qhov chaw welded los tsim lub zog kub, uas yog sib sau ua ke raws li kev sib txhuam vuam. Kev sib txhuam txhuam vuam, kos kev sib txhuam vuam, kev sib txhuam ntawm peb lub cev, thiab kev sib txhuam overlay vuam yog cov txheej txheem vuam uas tso siab rau cov cua sov uas tsim los ntawm kev sib txhuam kev sib txhuam ntawm lub taub hau thiab cov khoom ua haujlwm.
Kev sib txhuam vuam txheej txheem tuaj yeem faib ua plaub theem:
1. Kev hloov pauv ntawm kev sib txhuam ntawm cov tshuab hluav taws xob rau hauv thermal zog;
2. Yas deformation ntawm cov ntaub ntawv;
3. Forging siab nyob rau hauv cov txheej txheem thermoplastic;
4. Kev xaus ntawm intermolecular diffusion recrystallization vuam.
Piv nrog rau kev siv vuam tsoos, kev sib txhuam vuam tau qis dua qhov kub thiab lub zog siv, nrog rau kev siv hluav taws xob tsawg li 20% ntawm cov tsoos vuam. Ob qho tib si thiab cov hlau sib txawv tuaj yeem ua tau zoo welded. Thiab qhov tseeb vuam yog siab. Qhov siab tshaj plaws yuam kev nyob rau hauv tag nrho ntev ntawm lub pre combustion chamber ntawm diesel xyaw ua los ntawm kev sib txhuam vuam yog ± 0.1 millimeters. Kev ruaj khov vuam zoo thiab lub zog siab tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm cov khoom. Cov txheej txheem vuam tsis haum rau cov khoom siv vuam, thiab huv si, huv si, thiab tsis muaj kuab paug. Nyob rau tib lub sijhawm, thaj chaw tshav kub cuam tshuam me me, qhov vuam nrawm nrawm, thiab cov txheej txheem kub qis dua qhov kub ntawm qhov melting, zoo txo cov khoom tsis xws luag. Tsis zoo li cov arc vuam ib txwm siv, kev sib txhuam vuam tsis ua rau muaj kev phom sij xws li sparks, arc teeb, lossis cov pa phem, ua rau nws muaj txiaj ntsig zoo rau ib puag ncig kev noj qab haus huv thiab kev tiv thaiv kev nyab xeeb.
Nrog nws cov khoom zoo, muaj txiaj ntsig zoo, txuag hluav taws xob, thiab cov yam ntxwv tsis muaj kuab paug, Kev sib txhuam vuam tau nce ntxiv hauv cov teb xws li aerospace, nuclear zog tsheb, thiab kev tsim khoom siv tshuab. Nws tau txais kev saib xyuas zoo los ntawm cov teb chaws muaj kev lag luam thiab tau nqis peev ntau ntawm cov nyiaj hauv kev tsim kho tshuab thiab kev siv. Nws yog dav ntseeg tias kev sib txhuam vuam yog ib qho kev txhim khu kev qha, rov tsim tau, thiab txhim khu kev qha vuam tshuab.
Nrog rau kev ua haujlwm zoo heev ntawm kev sib txhuam vuam, cov cuab yeej no tuaj yeem ua tiav ntau yam kev kho, xws li cov txheej txheem tseem ceeb tawg, cov ntawv hlau qhov tsis raug, casting defects, quenching tawg, thiab lwm yam teeb meem. Kev sib txhuam ntsaws kho vuam yog cov txheej txheem vuam khov kho nrog cov vuam ceev ceev, me me tshav kub cuam tshuam cheeb tsam, thiab kho lub zog ncav cuag tshaj 90% ntawm lub cev lub zog. Cov txheej txheem kho yog tag nrho automated, txhim khu kev qha zoo, thiab cov khoom siv welded raws li cov qauv siv siab, txo cov kev lag luam thiab sij hawm poob ntawm cov khoom thiab cov khoom seem.
