Resistance welding yog ib txoj kev siv dav rau kev koom nrog cov hlau hauv ntau qhov kev lag luam, tab sis nws tsis tiv thaiv qhov tshwm sim ntawm cov kab nrib pleb hauv cov pob qij txha.Cov kab nrib pleb no tuaj yeem cuam tshuam cov qauv kev ncaj ncees ntawm cov khoom siv welded, ua rau muaj peev xwm ua tsis tiav.Kev nkag siab txog qhov ua rau cov kab nrib pleb hauv cov khoom siv vuam tsis sib haum yog qhov tseem ceeb rau kev tiv thaiv lawv qhov tshwm sim thiab ua kom cov khoom zoo welded.
- High Residual Stress:Ib qho ntawm cov laj thawj tseem ceeb rau cov kab nrib pleb hauv cov pob qij txha kuj yog qhov muaj kev ntxhov siab ntau ntxiv thaum lub sij hawm vuam txheej txheem.Raws li cov khoom siv welded sai txias thiab solidifies, nws cog lus, ua rau muaj kev ntxhov siab.Yog tias qhov kev ntxhov siab no dhau ntawm cov khoom siv lub zog, cov kab nrib pleb tuaj yeem tsim.
- Kev npaj khoom tsis txaus:Kev npaj cov khoom tsis zoo, xws li muaj cov kab mob ntawm cov kab mob los yog oxides, tuaj yeem cuam tshuam qhov kev tsim ntawm cov vuam muaj zog.Cov impurities no tuaj yeem tsim cov chaw tsis muaj zog hauv kev sib koom ua ke, ua rau nws muaj kev cuam tshuam rau kev tawg.
- Tsis yog Electrode Force:Kev siv kom zoo ntawm electrode quab yuam yog qhov tseem ceeb hauv kev ua haujlwm vuam.Kev quab yuam ntau dhau tuaj yeem ua rau ntau tshaj-compression thiab tshem tawm cov khoom, thaum lub zog tsis txaus yuav ua rau tsis tiav fusion.Ob qhov xwm txheej tuaj yeem ua rau tawg tsim.
- Lub sijhawm vuam tsis zoo:Lub sijhawm ntawm lub voj voog vuam yuav tsum tau ua tib zoo tswj.luv luv lub sij hawm vuam yuav tsis tso cai rau kom muaj cua sov txaus, ua rau tsis tiav fusion thiab muaj peev xwm tawg.
- Variability nyob rau hauv Vuam Parameters:Qhov tsis sib xws ntawm cov vuam tsis sib xws, xws li tam sim no thiab lub sijhawm, tuaj yeem ua rau muaj kev hloov pauv ntawm qhov zoo ntawm welds.Cov kev hloov pauv no tuaj yeem suav nrog thaj chaw ntawm qhov sib koom ua ke uas qhov kub tsis siab txaus rau kev sib xyaw kom zoo, tsim kom muaj cov cheeb tsam tawg.
- Khoom siv tsis sib haum:Cov khoom siv vuam nrog cov khoom thermal sib txawv tuaj yeem ua rau tawg.Cov nqi sib txawv ntawm thermal expansion thiab contraction tuaj yeem ua rau muaj kev ntxhov siab ntawm kev sib koom ua ke, txhawb kev tawg.
- Kev ua kom txias tsis txaus:Kev txias ceev ntawm cov welded sib koom ua ke tuaj yeem ua rau nws ua rau nkig thiab ua rau tawg.Kev kho cua sov tom qab vuam lossis kev tswj kom txias tuaj yeem pab daws qhov teeb meem no.
- Electrode Hnav:Nyob rau tib lub sijhawm, cov vuam electrodes tuaj yeem hnav lossis ua tsis zoo, ua rau tsis sib xws tam sim no thiab cuam tshuam qhov vuam zoo.Qhov no tuaj yeem ua rau cov ntsiab lus tsis muaj zog uas tuaj yeem tawg thaum kawg.
Txhawm rau txo qhov tshwm sim ntawm cov kab nrib pleb hauv cov pob qij txha tiv thaiv, cov neeg tsim khoom yuav tsum siv cov kev tswj xyuas nruj, tsis tu ncua tswj cov khoom siv vuam, thiab xyuas kom muaj kev cob qhia zoo rau cov welder.Tsis tas li ntawd, kev soj ntsuam nruj me ntsis ntawm cov khoom siv welded tuaj yeem pab txheeb xyuas thiab daws cov kab nrib pleb thaum ntxov, tiv thaiv cov khoom lag luam tsis ua tiav thiab ua kom ntseeg tau qhov kev ncaj ncees ntawm cov khoom kawg.
