Resistance chaw vuam yog cov txheej txheem siv dav hauv kev tsim khoom, tshwj xeeb hauv kev lag luam tsheb thiab aerospace. Txoj kev no koom nrog ob daim hlau ua ke los ntawm kev siv cov cua sov thiab lub zog los ntawm electrodes. Ib qho tseem ceeb parameter nyob rau hauv cov txheej txheem no yog electrode siab. Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv qhov tseem ceeb ntawm electrode siab nyob rau hauv qhov chaw welding tshuab thiab nws cov kev cuam tshuam rau qhov zoo ntawm welds.
Nkag siab Electrode Siab
Electrode siab, tseem hu ua vuam quab yuam los yog kev sib cuag siab, hais txog lub zog siv los ntawm vuam electrodes mus rau cov khoom ua haujlwm tau koom nrog. Lub siab no ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev vam meej. Lub luag haujlwm tseem ceeb ntawm electrode siab yog:
1. Ua kom muaj kev sib cuag hluav taws xob zoo
Txhawm rau kom muaj txiaj ntsig zoo ntawm qhov chaw vuam, txoj kab hluav taws xob tsis zoo yuav tsum muaj nyob nruab nrab ntawm cov electrodes thiab cov khoom ua haujlwm. Lub siab txaus ua kom muaj kev sib cuag hluav taws xob zoo, txo cov hluav taws xob tiv thaiv thiab ua kom cov dej ntws ntawm vuam tam sim no los ntawm kev sib koom ua ke. Qhov no, nyob rau hauv lem, pab txhawb lub tsim ntawm tshav kub yuav tsum tau rau lub vuam txheej txheem.
2. Txhawb nqa khoom deformation
Lub siab exerted los ntawm cov electrodes ua rau localized deformation nyob rau hauv lub workpiece khoom. Qhov no deformation tsim kev sib raug zoo ntawm ob lub workpieces, txhim khu cov metallurgical daim ntawv cog lus thaum vuam. Nws kuj tseem pab txhawm rau rhuav tshem cov kab mob hauv qhov chaw xws li oxides thiab coatings, ntxiv rau kev txhim kho vuam zoo.
3. Tswj kev tsim cov cua sov
Tsim nyog electrode siab pab tswj tus nqi ntawm cov cua sov tsim thaum lub sij hawm vuam. Kev kub siab ntau dhau tuaj yeem ua rau overheating, thaum lub siab tsis txaus yuav ua rau muaj cua sov tsis txaus. Ua kom tiav qhov sib npaug yog qhov tseem ceeb los tiv thaiv kev puas tsuaj rau cov khoom ua haujlwm thiab xyuas kom muaj kev sib txuas zoo.
Optimal Electrode Siab
Kev txiav txim siab qhov zoo electrode siab nyob ntawm ntau yam, nrog rau cov khoom siv welded, nws thickness, thiab vuam tam sim no. Cov neeg tsim khoom feem ntau muab cov lus qhia thiab kev qhia tshwj xeeb rau electrode siab raws li cov xwm txheej no. Tsis tas li ntawd, cov neeg ua haujlwm vuam tuaj yeem saib xyuas thiab kho cov electrode siab kom ua tiav qhov xav tau vuam zoo.
Kev cuam tshuam rau Weld Quality
Tsis txaus electrode siab tuaj yeem ua rau ntau qhov vuam tsis xws luag, xws li tsis tiav fusion, porosity, thiab tsis muaj zog weld bonds. Piv txwv li, kev kub siab ntau dhau tuaj yeem ua rau overwelding, ua rau deformation thiab puas rau workpieces. Yog li ntawd, kev tswj xyuas qhov tseeb electrode siab yog qhov tseem ceeb rau kev tsim cov welds zoo nrog cov khoom siv tshuab uas xav tau.
Nyob rau hauv qhov chaw welding tshuab, electrode siab yog ib qho tseem ceeb parameter uas ho cuam tshuam qhov zoo ntawm welds. Nws ua kom muaj kev sib cuag hluav taws xob zoo, txhawb nqa cov khoom deformation, thiab tswj kev tsim hluav taws xob. Txhawm rau kom ua tiav cov txiaj ntsig zoo, nws yog qhov tseem ceeb kom nkag siab txog cov khoom siv welded thiab ua raws li cov lus pom zoo electrode siab. Kev tswj kom zoo ntawm electrode siab yuav tsis tsuas yog txhim kho cov vuam zoo, tab sis kuj tseem ua rau kev ua tau zoo tag nrho thiab kev ntseeg siab ntawm cov txheej txheem vuam.
