Kev tiv thaiv kev tiv thaiv yog ib qho tseem ceeb ntawm lub zog cia qhov chaw vuam tshuab vim nws ncaj qha cuam tshuam rau cov txheej txheem vuam thiab qhov zoo ntawm welds tsim. Nkag siab txog yam uas cuam tshuam rau kev tiv thaiv yog qhov tseem ceeb rau kev txhim kho vuam kev ua tau zoo thiab ua kom ntseeg tau thiab ua tau zoo welds. Qhov tsab xov xwm no muab ib qho kev ntsuam xyuas ntawm cov yam uas ua rau muaj kev tiv thaiv nyob rau hauv lub zog cia chaw welding tshuab, qhia txog lawv cov kev cuam tshuam rau cov txheej txheem vuam.
- Qhov chaw ntawm lub workpieces: Qhov saum npoo ntawm lub workpieces raug welded muaj qhov cuam tshuam loj rau kev tiv thaiv kev tiv thaiv. Txhua yam kab mob, oxides, los yog cov coatings uas muaj nyob rau ntawm qhov chaw ua haujlwm tuaj yeem tsim kev thaiv thiab ua rau muaj kev sib cuag. Yog li ntawd, kev npaj kom zoo, nrog rau kev ntxuav thiab tshem tawm cov coatings, yog qhov tseem ceeb los xyuas kom meej cov hluav taws xob zoo ntawm cov electrodes thiab workpieces.
- Electrode Khoom thiab Txheej: Kev xaiv cov khoom siv electrode thiab txheej kuj cuam tshuam rau kev tiv thaiv kev tiv thaiv. Cov khoom siv electrode sib txawv muaj cov khoom siv hluav taws xob sib txawv, uas tuaj yeem cuam tshuam rau kev tiv thaiv kev sib cuag. Tsis tas li ntawd, kev siv cov coatings ntawm cov electrode nto, xws li tooj liab lossis nyiaj, tuaj yeem pab txo qis kev sib cuag los ntawm kev txhim kho conductivity thiab txo qis oxidation.
- Siab thiab Force Applied: Lub siab thiab quab yuam siv thaum lub vuam txheej txheem ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab tiv thaiv. Tsis txaus siab lossis quab yuam tuaj yeem ua rau tsis muaj hluav taws xob sib cuag ntawm cov electrodes thiab cov khoom ua haujlwm, ua rau muaj kev tiv thaiv ntau ntxiv. Kev kho kom raug thiab tswj lub siab thiab quab yuam kom muaj kev sib cuag txaus thiab txo qis kev tiv thaiv.
- Electrode Design and Condition: Tus tsim thiab cov xwm txheej ntawm electrodes cuam tshuam rau kev tiv thaiv. Cov yam ntxwv xws li cov duab electrode, thaj chaw saum npoo, thiab kev sib haum xeeb nrog cov khoom ua haujlwm cuam tshuam rau qhov chaw sib cuag thiab hluav taws xob conductivity. Nws yog ib qho tseem ceeb kom tsis tu ncua xyuas thiab tswj cov electrodes kom ntseeg tau tias lawv qhov kev pom zoo thiab txo qis kev tiv thaiv.
- Vuam tam sim no thiab Duration: Lub vuam tam sim no thiab lub sijhawm tseem cuam tshuam rau kev tiv thaiv. Cov vuam tam sim no siab dua tuaj yeem tsim hluav taws xob ntau dua, uas tuaj yeem ua rau cov khoom hloov pauv lossis deformation ntawm electrode thiab workpiece nto, cuam tshuam rau kev sib cuag. Ib yam li ntawd, lub sij hawm ntev vuam ntev tuaj yeem ua rau muaj kev tiv thaiv ntau ntxiv vim muaj kev cuam tshuam thermal. Kev tswj xyuas cov vuam tsis zoo yog tsim nyog los tswj kev sib cuag thiab txo qis kev sib cuag.
Kev tiv thaiv kev tiv thaiv nyob rau hauv lub zog cia qhov chaw vuam tshuab yog cuam tshuam los ntawm ntau yam, nrog rau qhov chaw ntawm lub workpieces, cov khoom siv electrode thiab txheej, siab thiab quab yuam siv, electrode tsim thiab mob, thiab vuam tam sim no thiab ntev. Los ntawm kev nkag siab txog cov xwm txheej no, cov neeg ua haujlwm thiab cov kws tshaj lij tuaj yeem siv cov kev ntsuas tsim nyog los txhim kho kev sib cuag thiab txo qis kev sib cuag, ua rau kev txhim kho vuam kev ua tau zoo, zoo dua welds, thiab ua kom tag nrho cov kev ua tau zoo hauv lub zog cia qhov chaw vuam txheej txheem.
