Yog hais tias muaj oxides los yog av nyob rau saum npoo ntawm lub workpiece thiab electrode ntawm qhov nruab nrab zaus qhov chaw vuam tshuab, nws yuav ncaj qha cuam tshuam rau kev sib cuag. Kev tiv thaiv kuj tseem cuam tshuam los ntawm electrode siab, vuam tam sim no, tam sim no ceev, vuam lub sij hawm, electrode zoo, thiab cov khoom siv. Cia wb mus saib hauv qab no.
Kev cuam tshuam ntawm electrode siab ntawm lub zog ntawm cov pob qij txha ib txwm txo qis nrog qhov nce ntawm electrode siab. Thaum nce electrode siab, nce vuam tam sim no los yog txuas lub sij hawm vuam tuaj yeem them rau qhov txo qis hauv kev ua haujlwm thiab tuav lub zog ntawm cov sib koom ua ke tsis hloov.
Qhov laj thawj tseem ceeb ntawm kev hloov pauv tam sim no tshwm sim los ntawm kev cuam tshuam ntawm vuam tam sim no yog qhov hloov pauv ntawm qhov hluav taws xob hauv daim phiaj hluav taws xob thiab kev hloov pauv impedance hauv qhov thib ob ntawm AC vuam tshuab. Kev hloov pauv ntawm impedance yog vim muaj kev hloov pauv hauv cov duab geometric ntawm lub voj voog lossis kev taw qhia ntawm qhov sib txawv ntawm cov hlau sib nqus nyob rau hauv lub voj voog thib ob.
Qhov ceev tam sim no thiab vuam kub yog cuam tshuam los ntawm cov dej ntws tam sim no los ntawm cov pob qij txha uas twb tau welded, nrog rau kev ua kom cov electrode tiv tauj cheeb tsam lossis qhov loj ntawm cov pob qij txha thaum lub sij hawm vuam, uas tuaj yeem txo qhov ceev tam sim no thiab vuam kub.
Kev cuam tshuam ntawm lub sijhawm vuam tuaj yeem ua tiav los ntawm kev siv lub sijhawm tam sim no thiab lub sijhawm luv luv, nrog rau qhov tsis tshua muaj tam sim no thiab lub sijhawm ntev, thiaj li yuav tau txais qee lub zog ntawm kev sib koom ua ke. Kev cuam tshuam ntawm cov duab electrode thiab cov khoom siv yuav nce ntxiv nrog rau kev deformation thiab hnav ntawm electrode xaus, ua rau muaj kev nce hauv qhov chaw sib cuag thiab txo qis hauv kev sib koom ua ke lub zog.
