Txias welding rau txhuas: nqi, daim ntawv thov, txheeb xyuas

Aluminium yog lub teeb taws siv hauv kev lag luam rau ntau xyoo lawm. Tshaj li ntawm lub sijhawm no nws tau raug tsim kom muaj kev vuam voom rau txhuas thiab nws txoj kev ua qia hlau yog tib txoj kev koom nrog kev sib tawg.

Dab tsi yog qhov txias vuam?

Txias vuam yog ib txoj kev koom ua ke ntawm cov hlau uas ua tsis muaj cua kub, hauv siab. Gluing yog nqa tawm vim yas deformation ntawm qhov loj thiab nws nkag mus rau hauv cov qhov chaw khi. Txias welding rau txhuas yog muaj dav thiab tsis tau tshwj xeeb kev npaj thiab cov cuab yeej ua haujlwm. Cov txheej txheem yuav siv ncaj qha rau hauv chav, hauv chav sov. Nws tsis yuav tsum tau tej thaum tshav kub kub qhov chaw siv arc welding.

Muaj pes tsawg leeg thiab yam ntxwv

Khaub thuas welding, nyob rau hauv qhov tseeb, yog ib tug nplaum rau hlau thiab tej zaum yuav muaj ib zaug xwb-tivthaiv los yog ob-tivthaiv muaj pes tsawg leeg, uas muaj xws li:

• Epoxy resins, uas tsim lub hauv paus ntawm kev ntsuas thiab muaj lub luag haujlwm rau lub uniformity thiab cov khoom zoo ntawm lub qhov muaj pes tsawg leeg.
• Hlau tivthaiv raws li ib tug muab tub lim.
• Ntxiv cov tshuaj thiab cov khoom siv ntxiv, kev txhim kho kev ua tiav, ua hauj lwm rau kev txhoj puab heev, cov yam ntxwv kub thiab lwm yam.

Muaj zog nyob ntawm nws qhov kev ua neej, siv tau thiab zoo ntawm kev npaj deg.

Raws li tsim nyog, qhov kev sib txuas yog qhov tseem muaj zog tshaj qhov sib npaug hlau, tab sis, raws li kev xyaum tau pom, lub seam tom qab tsevneeg yog qhov kev txiav txim siab ntawm qhov tsis muaj zog ntau tshaj qhov qub vuam. Yog li, nws pom zoo kom siv nws rau me me xwb.

Siv ntaub nplaum "Mob khaub thuas vuam txhuas" nyob rau hauv yuav luag txhua txhua muag khoom kho vajtse - ib tug zoo kawg tooj ntawm txawv teb chaws thiab domestic tuam ntxhab tsim no muaj pes tsawg leeg txawv los ntawm txhua lwm yam tsuas yog tus sab nraud tsim.

Mastic, raws li txoj cai, yog muag raws li ob txheej txheej, uas zoo li lub hnab yas, los yog kom yooj yim muab tso rau hauv ib lub pob cylindrical.

Ua ntej welding, tus nqi yuav tsum tau muab txiav tawm ntawm lub thooj (nruj me ntsis tshaj). Cov ntsiab lus ntawm vuam tom qab kneading nrog cov ntiv tes yog sai sai rau cov cheeb tsam xav.

Lub hauv paus ntsiab lus ntawm kev sib hloov ntawm kev sib txuas

Kev txhim kho ntawm cov txhuas hniav yog tsim los ntawm yas deformation.

Cov khoom uas yuav tsum tau koom rau thaum lub caij txias txias yog sib zog heev nrog txhua tus, vim tias cov txheej txheej sab nrauv tawg, qhov kev sib txuas ntawm kev sib tshuam sib txuas tshwm, ua kom muaj kev sib raug zoo.

Txhawm rau kom muaj kev sib txuas tau zoo dua, cov khoom yuav tsum yog zoo dua qub ua ntej, ntxuav ntawm plua plav.

Txias welding txoj kev

Cov cuab yeej ntawm koom nrog txhuas txhuas nyob rau hauv ib txoj hauv kev txias tau muab faib ua 3 txoj hau kev:

• Taub qab;
• Point;
• Suture.

Taub Qab Vuam

Nrog rau hom no, cov txhuas txhuas txhuas siv thiab tso clamped rau hauv cov pob zeb tshwj xeeb. Tsis tas li ntawd, ib qho kev siv zog siv rau lawv, uas tau hais los ntawm txoj kab xaj. Vim li ntawd, lub tshuab tau nrawm npaum li ntau tau, thiab yas deformation tshwm sim.

Hom no muaj qee qhov teeb meem:

• Nws yog tsis yuav luag txuas qhov ntev qhov chaw, vim hais tias lawv loj yog txwv los ntawm kev tsim kho ntawm clamping khoom;
• Ib qho ntawm cov khoom tsis nyob hauv qhov bushing-clamping yog deformed;
• Nws yog ib qho nyuaj rau tshem tawm cov khoom ntawm lub txiv duaj.

Chaw Welding

Txoj kev no yog siv los txhuas txhuas cov kab npoo npog sib tshooj. Siv cov punches tshwj xeeb. Qhov chaw ntawm qhov punch indented yog hu ua tus taw tes ntu. Welded cov ntsiab lus raug muab tso rau hauv txoj kab txuas tom qab lub caij nyoog qis.

Qhov zoo ntawm qhov no yog qhov qhaj ntawv ntawm qhov yuav tsum tau ua ntej kho ntawm qhov chaw thiab cov deformation tsawg ntawm cov hlau hauv cov chaw txuas. Qhov no yog qhov nquag siv vuas ntau rau txhuas. Nws tuaj yeem ua tsis tau clamping lossis rau qhov chaw seem.

Nqes vaum

Rau qhov tsim ntawm ib tug txuas txuas weld, qhov no ntawm vuam siv tau rollers, nruab nrab ntawm uas muaj tuaj koom ua ke los yog annular punches.

Welding yuav ua tau los ntawm ib qho kev hloov cov menyuam yaus uas nias qhov txhuas feem ntawm qhov nyiaj them yug, los yog ob txoj hlua uas clamp cov khoom ua ke.

Nyob ntawm qhov kev sib tshooj ntawm qhov ntu, tus menyuam lub voj voos tuaj yeem ua rau ntawm lub qhov ntom nti lossis kev tuav tes.

Nrog rau txoj kev txuas ntawm no, ib qho seam uas tsis muaj flange yog tau, tab sis nws qhov kev tsis zoo yog qhov thinning ntawm seem ntawm qhov chaw ntawm qhov chaw ntawm lub seam, uas ua rau muaj kev nkag tau thiab kev nkag ntawm qhov chaw hauv lub chaw no.

Txo no qhov tsis zoo los ntawm kev ua kom hla ntawm txoj kab uas ua hauj lwm saum npoo ntawm caj dab. Xwb, kev siv ntawm hom no yuav tsum raug zam.

Vuam tshuab rau txhuas

Shear welding yog ib txoj kev uas siv txhuas vuam txias. Nqa los ntawm compression nrog kev xaav tangential. Raws li ib tug ntawm cov txheej txheem no, tag nrho cov yeeb yaj duab oxide raug stripped, sib sau cov txuas ntawm kev sib koom tes. Txoj kev siv no yog siv rau kev lag luam kom muaj kev sib txuas rau cov xov hluav taws xob thiab cov xov tooj cua, xov tooj cua, kab khaub ncaws, ntau yam khoom siv rau cov khoom siv hauv tsev. Ib qho zoo tshaj plaws yog tau thaum welding aluminium nrog nws cov alloys (muab qhia tias qhov chaw ntawm lub npoo yog khaws cia huv). Nyob rau hauv cov ntaub ntawv ntawm lub slightest pa phem, nws yog yuav luag tsis ua tiav ib tug zoo kev txuas zoo.

Yuav kom tau ib qho zoo ntawm kev sib koom tes, nws yog ib qhov tsim nyog yuav tau siv cov phom sij kom cov hlau tuaj yeem khiav ntawm ob sab ntawm lub vuam chaw. Tsuas yog ua kom tiav ntawm tus mob no yuav ua kom tiav qhov tseeb tawm ntawm cov lus qhia sib txawv.

Lub seam ntawm daim ntawv txhuas tuaj yeem ua:

• Ncaj Ncees;
• Ntu;
• Nruam (ntawm txhua qhov ntev).
