Resistance chaw vuam yog ib txoj kev siv dav rau kev koom nrog cov khoom siv hlau hauv ntau qhov kev lag luam. Nws tso siab rau lub hauv paus ntsiab lus ntawm kev tsim kom muaj kev sib raug zoo ntawm ob qhov chaw hlau los ntawm kev siv cov cua sov thiab siab. Txawm hais tias cov txheej txheem nws tus kheej muaj txiaj ntsig zoo, ib qho tseem ceeb tshaj plaws uas feem ntau tau saib tsis pom yog qhov tseem ceeb ntawm kev tswj xyuas qhov chaw huv huv. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv vim li cas qhov chaw tu yog qhov tseem ceeb rau qhov chaw vuam tshuab.
- Txhim kho Weld Zoo: Cov khoom siv hlau huv huv kom ntseeg tau tias muaj kev vuam zoo dua. Txhua yam kab mob xws li xeb, xim, roj, lossis khib nyiab tuaj yeem cuam tshuam rau txoj kev vuam. Cov impurities no ua raws li kev thaiv, tiv thaiv kom zoo txaus ntawm tam sim no thiab cua sov thaum vuam. Thaum cov chaw raug ntxuav kom huv si, cov vuam tuaj yeem nkag mus thiab khi cov hlau zoo, ua rau muaj kev sib txuas zoo dua thiab txhim khu kev qha.
- Txhim kho conductivity: Txhawm rau tiv thaiv qhov chaw vuam kom ua haujlwm tau zoo, cov hluav taws xob tam sim no yuav tsum ntws los ntawm cov hlau qhov chaw uas muaj qhov tsis zoo. Qhov chaw qias neeg los yog kab mob ua rau muaj hluav taws xob tiv thaiv, ua rau muaj cua sov tsis sib xws thiab muaj peev xwm vuam tsis xws luag. Los ntawm kev ua kom lub ntsej muag huv si, koj ua kom pom cov hluav taws xob zoo tshaj plaws, uas yog qhov tseem ceeb rau kev ua tiav cov welds zoo ib yam.
- Extended Electrode Lub Neej: Nyob rau hauv qhov chaw welding, electrodes raug rau huab cua kub thiab siab. Qhov chaw qias neeg los yog kab mob tuaj yeem ua rau cov khoom siv hluav taws xob ntau dhau thiab kev puas tsuaj. Kev tu qhov chaw vuam tsis tu ncua tuaj yeem pab txuas lub neej ntawm electrodes, txo qhov zaus ntawm kev hloov pauv thiab tag nrho cov nqi tu.
- Txo qhov vuam tsis zoo: Cov chaw huv si ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv vuam xws li porosity, spatter, thiab nkag mus tsis tiav. Cov teeb meem no tuaj yeem ua rau lub vuam tsis muaj zog thiab cuam tshuam nws txoj kev ncaj ncees. Los ntawm kev tshem tawm cov kab mob ntawm qhov chaw, koj txo qhov kev pheej hmoo ntawm cov teeb meem no, kom ntseeg tau tias qhov kev sib koom ua ke ntawm cov khoom siv thiab kev ntseeg tau zoo.
- Kev nyab xeeb ua ntej: Kev ruaj ntseg vuam ib puag ncig yog ib qho teeb meem ntawm kev nyab xeeb. Cov kab mob ntawm cov hlau tuaj yeem ua rau muaj kev xav tsis thoob thaum lub sij hawm vuam, ua rau muaj pa taws, pa taws, lossis hluav taws kub. Kev tu kom zoo yuav txo tau cov kev pheej hmoo no, tsim kom muaj kev nyab xeeb ntawm kev ua haujlwm rau cov neeg ua haujlwm thiab txo qhov kev pheej hmoo ntawm qhov chaw ua haujlwm.
Hauv kev xaus, kev tuav cov hlau huv huv yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm qhov chaw vuam tshuab. Nws cuam tshuam ncaj qha rau vuam zoo, electrode ntev, thiab kev nyab xeeb tag nrho. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo ntxuav qhov chaw raws li kev coj ua hauv koj qhov kev ua haujlwm vuam. Los ntawm kev ua li ntawd, koj yuav tsis tsuas yog txhim kho qhov zoo thiab sib xws ntawm koj cov welds tab sis kuj txhim khu lub neej ntev ntawm koj cov cuab yeej thiab tsim kom muaj kev nyab xeeb rau txhua tus neeg koom tes.
