Deformation yog ib qho kev txhawj xeeb hauv cov txiv ntoo qhov chaw vuam, vim tias cov khoom siv welded yuav raug hloov pauv tsis xav tau thaum lub sijhawm ua haujlwm.Txawm li cas los xij, los ntawm kev siv cov tswv yim zoo thiab ua raws li cov kev coj ua zoo tshaj plaws, nws muaj peev xwm txo qis thiab tiv thaiv deformation hauv cov txiv ntoo qhov vuam.Kab lus no tshawb txog ntau yam tswv yim kom ua tiav qhov tsis muaj qhov sib txawv ntawm cov welds thiab tswj cov txheej txheem kev ncaj ncees ntawm cov khoom ua haujlwm.
- Txoj Kev Vuam Zoo: Txhawm rau tiv thaiv kev deformation, nws yog ib qho tseem ceeb los tsim kom muaj kev npaj vuam zoo sib xws.Pib vuam los ntawm qhov chaw nruab nrab thiab nce mus rau sab nraud, tso cai rau maj mam txias thiab kev ntxhov siab faib thoob plaws hauv qhov chaw ua haujlwm.
- Kev xaiv cov khoom siv: Xaiv cov khoom siv nrog cov thermal expansion coefficients tuaj yeem pab txo qhov kev pheej hmoo ntawm deformation.Tsis txhob vuam cov ntaub ntawv sib txawv nrog cov khoom sib txawv kom muaj qhov sib xws thaum cua sov thiab txias.
- Optimal Welding Parameters: Calibrate qhov vuam tsis raws li cov khoom thickness thiab kev sib koom tsim.Ua kom ntseeg tau zoo ib yam thiab tsim nyog tam sim no, lub sijhawm, thiab lub siab yuav pab ua kom muaj kev sib npaug ntawm cov cua sov thiab txo qhov cuam tshuam.
- Workpiece Fixturing: Zoo fixturing thiab clamping yog ib qho tseem ceeb kom muaj kev ruaj ntseg workpiece thaum vuam.Ua kom ruaj ntseg tuav cov khoom nyob rau hauv qhov chaw kom tsis txhob txav thiab distortion thaum lub vuam txheej txheem.
- Preheating: Hauv qee kis, preheating lub workpieces tuaj yeem pab tau.Preheating pab txo qhov kub thiab txias ntawm qhov chaw weld thiab cov khoom nyob ib puag ncig, yog li txo qis thermal poob siab thiab deformation.
- Vuam ceev: Tswj qhov vuam ceev yog qhov tseem ceeb hauv kev tiv thaiv deformation.Qhov sib npaug thiab ruaj khov vuam ceev tso cai rau cov khoom siv hluav taws xob zoo sib xws thiab txo qhov kev pheej hmoo ntawm cov cua sov hauv zos.
- Tom qab Weld Thaum tshav kub kub kho: Xav txog kev kho cua sov tom qab vuam kom txo cov kev ntxhov siab thiab ua kom ruaj khov ntawm cov welded sib koom ua ke, uas tuaj yeem pab tiv thaiv kev deformation dhau sijhawm.
- Tswj Cooling: Siv cov kev tswj cua txias kom txo tau qhov kev pheej hmoo ntawm kev ua kom txias sai sai vim qhov deformation.Kev ua kom txias qeeb thiab tsis sib xws tuaj yeem ua tiav los ntawm kev siv cov ntaub ntawv insulating lossis qhov chaw tswj qhov kub thiab txias.
Tiv thaiv kom tsis txhob deformation hauv cov txiv ntoo qhov chaw vuam yuav tsum muaj kev qhia dav dav uas suav nrog kev xaiv cov khoom siv, kev kho kom raug, kev pom kev vuam tsis zoo, thiab tswj cov txheej txheem txias.Los ntawm kev ua raws li kev npaj vuam zoo ib ntus thiab xav txog kev kho cua sov los yog tom qab vuam thaum tsim nyog, cov neeg ua haujlwm tuaj yeem txo cov kev ntxhov siab thermal thiab ua tiav qhov tsis muaj qhov sib txawv.Kev ua raws li cov txheej txheem no yuav tsis tsuas yog ua kom muaj qhov zoo ntawm cov pob qij txha welded tab sis kuj tswj cov txheej txheem kev ncaj ncees ntawm cov khoom, ua rau lawv haum rau ntau yam kev siv.
