Resistance welding yog ib txoj kev tsim khoom siv dav siv uas tso siab rau cov ntsiab lus ntawm cov hluav taws xob tiv thaiv los tsim cov ntawv cog lus muaj zog thiab ruaj khov ntawm cov khoom hlau.Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog lub luag haujlwm tseem ceeb uas ua rau kev ua kom sov hauv cov khoom ntawm lub tshuab vuam tsis kam.
Kev ua haujlwm vuam yog feem ntau ua haujlwm hauv ntau qhov kev lag luam, suav nrog tsheb, aerospace, thiab hluav taws xob, vim nws muaj peev xwm tsim cov welds zoo.Cov txheej txheem suav nrog kev siv lub siab rau ob daim hlau thaum hla cov hluav taws xob los ntawm lawv.Cov hluav taws xob tsis kam ntawm qhov sib txuas ntawm ob daim ua kom sov, ua rau lawv yaj thiab fuse ua ke.
Lub hauv paus tseem ceeb uas cuam tshuam rau cov txheej txheem cua sov hauv cov tshuab vuam vuam yog hluav taws xob tsis kam thiab tam sim no ntws.Wb delve rau hauv yuav ua li cas tsis kam cuam tshuam rau cov txheej txheem cua sov:
- Khoom siv:Qhov hluav taws xob tsis kam ntawm cov khoom siv yog cuam tshuam los ntawm nws cov khoom siv hauv paus, xws li nws cov resistivity thiab conductivity.Cov ntaub ntawv uas muaj kev tiv thaiv siab yuav tsum muaj hluav taws xob ntau dua los ua kom sov, thaum cov khoom siv hluav taws xob ua kom sov sai dua.Resistance vuam tshuab yog tsim los kom haum rau ntau yam ntaub ntawv los ntawm kev kho cov ntaub ntawv tam sim no thiab siab raws li.
- Electrode Tsim:Kev tsim cov vuam electrodes kuj cuam tshuam rau cov txheej txheem cua sov.Electrodes yuav tsum tau ua los ntawm cov khoom uas muaj peev xwm tiv taus kub thiab muaj hluav taws xob zoo conductivity.Qhov loj thiab cov duab ntawm cov electrodes cuam tshuam rau kev faib cov cua sov thiab siab, uas tuaj yeem cuam tshuam qhov zoo ntawm cov vuam.
- Tiv tauj Resistance:Kev tiv thaiv kev sib cuag ntawm qhov sib cuam tshuam ntawm cov electrodes thiab workpieces plays lub luag haujlwm tseem ceeb hauv cov txheej txheem cua sov.Kev sib raug zoo electrode thiab kev saib xyuas yog qhov tseem ceeb los xyuas kom tsis txhob muaj kev sib cuag.Kev tiv thaiv siab tuaj yeem ua rau tsis muaj cua sov thiab tsis muaj zog welds.
- Tswj tam sim no:Kev tswj xyuas meej ntawm cov vuam tam sim no yog qhov tseem ceeb rau kev ua tiav cov vuam zoo ib yam thiab zoo.Qib tam sim no yuav tsum tau ua kom haum rau cov khoom tshwj xeeb tau koom nrog thiab cov khoom siv vuam xav tau.Tsis txaus tam sim no tuaj yeem ua rau tsis tiav fusion, thaum lub sijhawm tam sim no ntau dhau tuaj yeem ua rau overheating thiab muaj peev xwm puas tsuaj rau cov khoom ua haujlwm.
- Thaum tshav kub kub Distribution:Nyob rau hauv kev ua haujlwm vuam, nws yog ib qho tseem ceeb los tswj kev faib cov cua sov.Cov cua kub tsis sib xws tuaj yeem ua rau muaj qhov tsis xws luag xws li warping, cracking, los yog tsis tiav.Kev sib raug zoo electrode thiab kev faib tawm siab pab kom muaj cua sov zoo thiab muaj kev sib raug zoo.
Hauv kev xaus, kev nkag siab txog kev cuam tshuam ntawm hluav taws xob tsis kam ntawm cov txheej txheem cua sov hauv cov tshuab vuam vuam yog qhov tseem ceeb rau kev ua tiav cov khoom siv vuam zoo thiab cov khoom zoo.Cov neeg tsim khoom yuav tsum ua tib zoo xav txog cov khoom siv, tsim qauv electrode, tiv thaiv kev tiv thaiv, kev tswj tam sim no, thiab kev faib hluav taws xob kom ua kom zoo dua cov txheej txheem vuam rau lawv cov kev siv tshwj xeeb.Los ntawm kev ua li ntawd, lawv tuaj yeem ua kom ntseeg tau tias cov khoom siv ruaj khov thiab tsis muaj qhov tsis zoo welded Cheebtsam, pab txhawb rau tag nrho cov khoom zoo thiab kev ntseeg siab ntawm lawv cov khoom.
