Resistance chaw vuam yog ib txoj kev siv dav hauv ntau yam lag luam, suav nrog tsheb thiab kev tsim khoom.Txhawm rau kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov cuab yeej siv, nws yog ib qho tseem ceeb kom nkag siab thiab ua raws li cov txheej txheem kev khiav hauj lwm kom raug thaum siv cov khoom siv hluav taws xob tiv thaiv vuam tshuab.
Resistance spot welding yog txheej txheem uas koom nrog ob lossis ntau cov ntawv hlau ua ke los ntawm kev siv cua sov thiab siab ntawm cov ntsiab lus tshwj xeeb.Lub tshuab maub los ua lub luag haujlwm tseem ceeb hauv cov txheej txheem no, tswj lub zog thiab lub sijhawm ntawm cov vuam kom ua tiav daim ntawv cog lus muaj zog thiab txhim khu kev qha.Ntawm no, peb yuav qhia txog cov txheej txheem kev nyab xeeb tseem ceeb rau kev khiav hauj lwm qhov chaw vuam tshuab maub los.
1. Kev cob qhia thiab kev paub:
Ua ntej kev khiav hauj lwm lub tshuab maub los, xyuas kom meej tias cov neeg ua haujlwm tau txais kev cob qhia txaus hauv nws qhov kev siv.Paub koj tus kheej nrog cov cuab yeej siv phau ntawv thiab cov lus qhia kev nyab xeeb.Kev nkag siab txog lub tshuab cov khoom, kev ua haujlwm, thiab kev phom sij yog qhov tseem ceeb rau kev ua haujlwm nyab xeeb.
2. Cov iav tiv thaiv:
Ib txwm hnav cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) thaum ua haujlwm nrog lub tshuab vuam qhov chaw.Qhov no suav nrog cov tsom iav kev nyab xeeb, cov hnab looj tes vuam, cov khaub ncaws tiv thaiv nplaim taws, thiab lub kaus mom hlau txuas nrog lub ntsej muag tiv thaiv.PPE pab tiv thaiv qhov muaj peev xwm arc flash, sparks, thiab kub hnyiab.
3. Kev Npaj Ua Haujlwm:
Tsim kom muaj chaw ua haujlwm nyab xeeb thiab txhim khu kev qha.Xyuas kom muaj qhov cua zoo kom tawg welding pa taws thiab gases.Khaws thaj chaw ua haujlwm kom huv si thiab tsis muaj cov khoom tawg yooj yim.Kos thiab tuav txoj hauv kev kom txav mus los thiab khiav thaum muaj xwm txheej ceev.
4. Kev tshuaj xyuas tshuab:
Ua ntej txhua qhov kev siv, tshuaj xyuas lub tshuab maub los rau qhov pom kev puas tsuaj, kev sib txuas xoob, lossis cov khoom siv tsis zoo.Xyuas kom meej tias cov av hauv av tsis zoo thiab ua haujlwm raug.Hais txog tej teeb meem tam sim ntawd kom tsis txhob muaj xwm txheej.
5. Fais fab mov:
Xyuas kom meej tias lub hwj chim mov rau lub tshuab maub los yog ruaj khov thiab nyob rau hauv qhov ntsuas qhov voltage.Siv cov cuab yeej tiv thaiv hluav taws xob tsim nyog thiab lub zog txias kom tsis txhob muaj teeb meem hluav taws xob.
6. Kev Kho Electrode Zoo:
Tsis tu ncua xyuas thiab tswj cov vuam electrodes.Ntxuav, ntse, thiab hnav cov electrodes raws li xav tau.Kev saib xyuas electrode kom zoo ua kom zoo sib xws.
7. Vuam txheej txheem chaw:
Teem lub tshuab maub los rau qhov pom zoo welding tsis raws li cov khoom siv, thickness, thiab daim ntawv thov vuam.Tsis txhob overloading cov cuab yeej tshaj nws lub peev xwm.
8. Saib xyuas cov txheej txheem vuam:
Ua tib zoo saib xyuas cov txheej txheem vuam thaum ua haujlwm.Npaj los cuam tshuam cov txheej txheem yog tias koj pom qhov tsis sib xws lossis cov tsos mob ntawm overheating.
9. Cov txheej txheem xwm txheej ceev:
Paub koj tus kheej nrog cov txheej txheem kaw thaum muaj xwm txheej ceev thiab qhov chaw nres xwm ceev.Muaj cov hluav taws tua hluav taws thiab cov khoom siv pab thawj zaug tau yooj yim thaum muaj xwm txheej.
10. Kev soj ntsuam tom qab Weld:
Tom qab ua tiav cov txheej txheem vuam, tshuaj xyuas cov welds kom zoo thiab kev ncaj ncees.Xyuas kom lawv ua tau raws li qhov xav tau tshwj xeeb thiab cov qauv.
Kev khiav hauj lwm qhov chaw vuam tshuab tswj kev nyab xeeb yog qhov tseem ceeb rau kev tiv thaiv kev sib tsoo, kev raug mob, thiab khoom puas tsuaj.Kev cob qhia tsis tu ncua, ua raws li cov lus qhia kev nyab xeeb, thiab kev saib xyuas kom zoo yog qhov tseem ceeb ntawm kev ua kom muaj kev nyab xeeb ua haujlwm.Los ntawm kev ua raws li cov lus qhia no, koj tuaj yeem pab tswj qhov chaw ua haujlwm ruaj ntseg thiab ua tiav cov vuam zoo hauv koj cov haujlwm.
