Spot welding yog cov txheej txheem siv dav hauv kev lag luam tsim khoom, paub txog nws cov txiaj ntsig thiab nrawm hauv kev koom nrog cov hlau ua haujlwm. Txawm li cas los xij, vuam workpieces ntawm qhov tsis sib xws thiab cov ntaub ntawv sib txawv tuaj yeem ua haujlwm nyuaj. Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog cov txheej txheem thiab kev txiav txim siab rau qhov zoo ntawm qhov chaw vuam xws li workpieces.
1. Kev xaiv cov khoom siv:
Ua ntej dhia mus rau hauv cov txheej txheem vuam, nws yog ib qho tseem ceeb uas yuav tsum xaiv qhov tsim nyog vuam electrodes thiab cov chaw rau cov ntaub ntawv raug koom. Cov hlau sib txawv muaj qhov sib txawv ntawm cov khoom siv hluav taws xob thiab cov cua sov dissipation, uas tuaj yeem cuam tshuam qhov zoo ntawm vuam. Piv txwv li, yog tias koj tab tom vuam hlau rau txhuas, koj yuav xav tau cov electrodes tshwj xeeb tsim rau cov khoom siv sib txawv.
2. Welding Parameters:
Qhov tseem ceeb ntawm qhov chaw vuam yog vuam tam sim no, vuam lub sij hawm, thiab electrode quab yuam. Cov kev txwv no yuav tsum tau hloov kho raws li cov ntaub ntawv thickness thiab hom. Cov ntaub ntawv tuab feem ntau xav tau cov vuam tam sim no siab dua thiab lub sijhawm vuam ntev dua. Rau cov ntaub ntawv sib txawv, nrhiav qhov sib npaug yog qhov tseem ceeb kom tsis txhob muaj kev vuam dhau los yog qis dua.
3. Electrode Tsim:
Kev cai electrode tsim tuaj yeem pab faib cov vuam quab yuam sib npaug ntawm cov khoom ua haujlwm, txawm tias lawv muaj qhov sib txawv. Piv txwv li, cov kauj ruam electrode nrog ib txoj kab uas hla loj dua ntawm ib sab tuaj yeem siv los xyuas kom muaj qhov sib txuas zoo ntawm cov khoom tuab thaum tiv thaiv kev kub nyhiab ntawm qhov nyias nyias.
4. Tack Welding:
Tack welding yuav ua rau me me, ua ntej welds ntawm cov ntsiab lus ntawm kev sib koom ua ke kom tuav cov khoom ua ke ib ntus. Qhov no tuaj yeem pab tau tshwj xeeb tshaj yog thaum cuam tshuam nrog cov khoom sib txawv. Tack welds xyuas kom meej tias cov workpieces nyob twj ywm thaum lub sij hawm kawg vuam txheej txheem.
5. Vuam Sequence:
Qhov sib lawv liag uas koj txuas cov khoom sib txawv tuaj yeem cuam tshuam qhov zoo ntawm kev sib koom ua ke. Nws yog feem ntau pom zoo kom pib nrog cov khoom siv thinnest thiab tom qab ntawd txav mus rau qhov tuab dua. Qhov no tiv thaiv cov cua kub ntau dhau ntawm cov khoom siv thinner, uas tuaj yeem ua rau kub hnyiab los yog cuam tshuam.
6. Kev kuaj thiab tshuaj xyuas:
Tom qab ua tiav qhov vuam, nws yog ib qho tseem ceeb los xyuas qhov sib koom ua ke kom zoo. Ntau yam kev sim uas tsis yog kev puas tsuaj, xws li kev tshuaj xyuas qhov muag, kev tshuaj ntsuam xyuas qhov muag, lossis kev kuaj X-ray, tuaj yeem siv los xyuas kom meej qhov kev sib raug zoo.
7. Kev xyaum thiab kev cob qhia:
Vuam cov ntaub ntawv sib txawv thiab cov khoom ua haujlwm tsis sib xws tuaj yeem yog qhov kev txawj ntse. Kev cob qhia tsim nyog thiab kev xyaum ua haujlwm yog qhov tseem ceeb rau cov neeg siv vuam los tsim cov kev txawj ntse uas xav tau los tsim cov pob qij txha zoo hauv cov xwm txheej zoo li no.
Nyob rau hauv xaus, welding workpieces ntawm tsis sib npaug thickness thiab sib txawv cov ntaub ntawv nrog ib tug welding tshuab yuav tsum tau ceev faj saib xyuas ntawm cov ntaub ntawv, welding tsis, electrode tsim, thiab welding sequence. Los ntawm kev ua raws li cov lus qhia no thiab kev nqis peev hauv cov cuab yeej tsim nyog, cov neeg tsim khoom tuaj yeem ua tiav cov welds muaj zog thiab txhim khu kev qha nyob rau hauv ntau yam kev siv, txawm tias ntsib nrog cov khoom sib tw nyuaj.
