Tiv thaiv kom tsis txhob deformation thiab tshem tawm cov kev ntxhov siab uas nyob ib puag ncig yog qhov tseem ceeb hauv kev siv lub taub qab vuam tshuab kom ua tiav cov welds zoo thiab zoo.Welding-induced deformations thiab kev ntxhov siab tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm kev sib koom tes thiab ua rau muaj teeb meem kev ua haujlwm hauv cov qauv welded.Tsab ntawv xov xwm no tshawb txog cov tswv yim los tiv thaiv kev deformation thiab kev ntxhov siab hauv cov tshuab vuam taub qab, hais txog lawv qhov tseem ceeb hauv kev ua kom ntseeg tau cov txiaj ntsig weld txhim khu kev qha thiab ntev weldments.
Tiv thaiv kom tsis txhob deformation thiab kev ntxhov siab nyem hauv Butt Vuam Tshuab:
- Ua kom haum-Up thiab Alignment: xyuas kom meej haum thiab ua kom zoo ntawm cov khoom ua ntej vuam yog qhov tseem ceeb los tiv thaiv deformation.Kev ua kom haum zoo txo qis qhov sib txawv ntawm cov khoom siv, txo qhov xav tau rau kev vuam ntau dhau thiab txo qhov kev pheej hmoo ntawm kev cuam tshuam.
- Fixturing txaus: Siv cov khoom siv los yog cov clamps uas muab kev ruaj ntseg thiab zoo ib yam thaum lub sij hawm vuam pab tswj lub workpiece txav thiab tiv thaiv kev cuam tshuam.Kev txhim kho kom zoo tswj kev sib koom ua ke thiab txo qis kev ntxhov siab.
- Tswj Cov Cuab Yeej Hluav Taws Xob: Kev tswj cov cua sov tawm thaum lub sij hawm vuam yog qhov tseem ceeb los tiv thaiv overheating thiab distortion ntau dhau.Welders tuaj yeem siv cov txheej txheem vuam tsim nyog thiab cov txheej txheem los tswj cov khoom siv hluav taws xob thiab tsis txhob muaj cua sov ntau dhau.
- Intermittent Vuam: Rau cov welds ntev los yog cov ntaub ntawv tuab, kev sib tshuam vuam nrog lub caij txias txaus tuaj yeem pab tswj cov cua sov thiab txo qhov cuam tshuam.Kev sib txuas welding tso cai rau cov khoom ua haujlwm kom txias ntawm cov vuam hla dhau, tiv thaiv kev ntxhov siab ntau dhau.
- Kev Tiv Thaiv Kev Nyuaj Siab Thaum Tshav Kub Kub: Kev kho cua sov tom qab vuam tuaj yeem siv los txo cov kev ntxhov siab nyob hauv qhov vuam.Tswj cua sov thiab cua txias thaum kho kev ntxhov siab pab kom rov faib cov kev ntxhov siab thiab txo qis kev cuam tshuam.
- Kev Tsim Nyog ntawm Vuam: Kev siv cov txheej txheem vuam tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv ntau qhov kev vuam, tuaj yeem txo qhov cuam tshuam.Maj mam welding los ntawm qhov chaw mus rau cov npoo los yog alternating ntawm ob sab yuav faib residual stresses ntau tus sib npaug.
- Back Purging: Thaum vuam nyias-walled cov ntaub ntawv, rov qab purging nrog cov roj inert tuaj yeem tiv thaiv kev tsim cov vuam ntau dhau thiab qhov ua rau cuam tshuam.
Hauv kev xaus, kev tiv thaiv kev deformation thiab kev ntxhov siab nyem hauv lub pob tw vuam tshuab yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig kev txhim khu kev qha thiab tswj kev ua haujlwm zoo.Kev sib haum xeeb thiab kev sib raug zoo, kev kho kom tsim nyog, kev tswj xyuas cov cua sov, kev sib tshuam vuam, kev kho cua sov kho kev ntxhov siab, kev sib txuas kom zoo, thiab rov qab purging yog cov tswv yim tseem ceeb los txo qis kev cuam tshuam thiab txo qis kev ntxhov siab.Kev nkag siab txog qhov tseem ceeb ntawm cov tswv yim no txhawb nqa cov neeg siv khoom los txhim kho cov txheej txheem vuam thiab ua tau raws li cov qauv kev lag luam.Hais txog qhov tseem ceeb ntawm kev tiv thaiv kev deformation thiab kev ntxhov siab pab txhawb kev nce qib hauv vuam thev naus laus zis, txhawb kev ua tau zoo hauv cov hlau koom nrog ntau hom kev lag luam.
