Resistance chaw vuam yog txheej txheem siv dav hauv ntau qhov kev lag luam rau kev koom nrog cov khoom siv hlau. Nws tso siab rau kev siv lub siab thiab cua sov los ua kom muaj zog thiab ruaj khov. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv qhov tseem ceeb ntawm vuam siab nyob rau hauv qhov chaw vuam tshuab thiab nws cov kev cuam tshuam rau qhov zoo thiab kev ncaj ncees ntawm welded pob qij txha.
1. Vuam Siab: Tus yuam sij rau kev vam meej welds
Vuam siab yog ib qho tseem ceeb parameter nyob rau hauv qhov kev tiv thaiv qhov chaw vuam txheej txheem. Nws ncaj qha cuam tshuam qhov zoo ntawm cov vuam thiab yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo ib yam thiab txhim khu kev qha. Lub vuam siab yog lub zog siv rau cov khoom ua haujlwm, compressing lawv ua ke thaum lub tshuab hluav taws xob dhau los ntawm kev sib koom ua ke, ua rau cov hlau yaj thiab tsim ib daim ntawv cog lus. Qhov tseem ceeb ntawm vuam siab tuaj yeem nkag siab raws li hauv qab no:
2. Ua kom muaj kev sib cuag zoo
Yuav kom tsim tau ib qho kev txhim khu kev qha, nws yog ib qho tseem ceeb los xyuas kom meej kev sib cuag ntawm ob workpieces. Kev tsis txaus siab tuaj yeem ua rau kev sib cuag tsis zoo, ua rau cov cua sov tsis sib xws thiab cov welds tsis muaj zog. Tsis txaus siab kuj tuaj yeem ua rau arcing, uas tuaj yeem ua rau cov khoom ua haujlwm thiab cov vuam electrodes puas.
3. Tswj kev tsim cov cua sov
Vuam siab ua lub luag haujlwm tseem ceeb hauv kev tswj cov cua sov uas tshwm sim thaum lub vuam txheej txheem. Qhov siab npaum li cas kom ntseeg tau tias cov hluav taws xob tam sim no ntws sib npaug los ntawm kev sib koom ua ke, tiv thaiv overheating lossis underheating ntawm cov hlau. Qhov kev tswj no yog qhov tseem ceeb rau kev tiv thaiv qhov tsis xws luag xws li kub hnyiab los yog tsis tiav fusion.
4. Ua kom muaj kev sib haum xeeb
Kev sib raug zoo yog qhov tseem ceeb hauv qhov chaw welding, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas muaj qhov loj ntawm cov khoom siv welded. Kev tuav lub vuam zoo sib xws ua kom ntseeg tau tias txhua qhov vuam ua tau raws li cov qauv zoo tib yam, txo qhov kev pheej hmoo ntawm qhov tsis xws luag thiab rov ua haujlwm dua.
5. Kev cuam tshuam rau Weld Strength
Lub vuam siab ncaj qha cuam tshuam lub zog ntawm qhov kawg weld. Kev tsim nyog ua kom ntseeg tau tias cov hlau molten yog txaus nyem ua ke, ua rau muaj kev sib raug zoo ntawm cov hlau. Hauv qhov sib piv, qhov tsis txaus siab tuaj yeem ua rau cov welds tsis muaj zog uas tsis tuaj yeem tiv taus qhov kev xav tau lossis kev ntxhov siab.
6. Kev saib xyuas thiab kho qhov siab
Txhawm rau kom ua tiav qhov zoo tshaj plaws vuam zoo, qhov chaw vuam tshuab tau nruab nrog cov txheej txheem los saib xyuas thiab kho qhov vuam siab. Cov tshuab no xyuas kom meej tias lub siab raug siv tas li thoob plaws hauv cov txheej txheem tsim khoom.
7. Cov lus xaus
Hauv kev xaus, qhov tseem ceeb ntawm vuam siab nyob rau hauv qhov chaw vuam tshuab tsis tuaj yeem overstated. Nws yog ib qho tseem ceeb parameter uas ncaj qha cuam tshuam qhov zoo, kev ncaj ncees, thiab lub zog ntawm cov pob qij txha welded. Txhawm rau kom muaj kev vam meej welds thiab ua tau raws li cov qauv zoo, cov neeg tsim khoom yuav tsum tau ua tib zoo saib xyuas qhov tsim nyog vuam siab thaum lub sij hawm vuam txheej txheem. Qhov kev mloog rau kev nthuav dav no thaum kawg ua rau muaj kev nyab xeeb thiab txhim khu kev qha cov khoom lag luam hauv ntau qhov kev lag luam uas tsis muaj qhov chaw vuam siv.
