Lub zog cia qhov chaw vuam tshuab yog dav siv nyob rau hauv ntau yam lag luam rau lawv lub peev xwm los tsim kom muaj zog thiab txhim khu kev qha welds. Peb qhov tseem ceeb ntawm cov txheej txheem vuam yog ua ntej-siab, siab, thiab tuav lub sijhawm. Kev nkag siab qhov tseem ceeb ntawm cov kev txwv no thiab lawv cov kev hloov kho kom raug yog qhov tseem ceeb los xyuas kom meej qhov zoo ntawm vuam zoo. Kab lus no muab cov lus piav qhia dav dav ntawm kev kub siab ua ntej, siab, thiab tuav lub sijhawm hauv lub zog cia qhov chaw vuam tshuab, qhia txog lawv lub luag haujlwm thiab cov yam ntxwv uas cuam tshuam rau lawv cov kev hloov kho.
- Pre-Pressure: Pre-pressure, tseem hu ua lub sij hawm nyem, yog hais txog thawj daim ntawv thov ntawm electrode quab yuam ntawm lub workpieces ua ntej lub vuam tam sim no qhib. Lub hom phiaj ntawm kev kub siab ua ntej yog los tsim kom muaj kev sib cuag ruaj khov thiab zoo ib yam ntawm cov electrodes thiab cov khoom ua haujlwm, ua kom muaj kev sib raug zoo thiab txo qis qhov sib txawv ntawm huab cua los yog cov khoom paug. Pre-pressure pab tsim ib qho kev txhim khu kev qha hluav taws xob thiab thermal kev sib txuas ntawm electrodes thiab workpieces, ua rau kev txhim kho weld zoo. Lub sij hawm ntawm pre-pressure nyob ntawm tej yam xws li workpiece khoom, thickness, thiab kev sib koom configuration.
- Siab: Lub siab, tseem hu ua lub sijhawm vuam lossis lub sijhawm vuam tam sim no, yog lub sijhawm uas cov vuam tam sim no ntws los ntawm cov khoom ua haujlwm, tsim cov cua sov tsim nyog rau fusion. Lub siab yuav tsum tau siv nrog lub zog txaus los xyuas kom meej cov khoom tsim nyog deformation thiab ua tiav kev sib raug zoo ntawm cov khoom ua haujlwm. Lub sijhawm ntawm lub siab yog txiav txim siab los ntawm cov khoom xws li cov khoom siv ua haujlwm, tuab, qhov xav tau vuam lub zog, thiab lub peev xwm vuam tshuab. Nws yog ib qho tseem ceeb kom sib npaug lub sij hawm siab kom tsis txhob muaj cua sov ntau dhau thiab muaj peev xwm ua haujlwm puas tsuaj thaum ua kom tiav fusion ntawm qhov sib koom ua ke.
- Tuav Sijhawm: Tuav lub sijhawm, tseem hu ua post-pressure lossis forge time, yog lub sijhawm tom qab txiav tawm ntawm qhov vuam tam sim no. Thaum lub sij hawm no, lub siab yog tswj nyob rau hauv lub workpieces kom tso cai rau solidification thiab txias ntawm lub vuam. Tuav lub sij hawm yog qhov tseem ceeb heev rau kev tsim cov hlau nplaum muaj zog thiab kev tiv thaiv ntawm cov khoom siv vuam xws li tawg lossis porosity. Lub sijhawm tuav lub sijhawm yog nyob ntawm cov khoom xws li cov khoom siv ua haujlwm, kev sib koom ua ke, thiab kev xav kom txias. Lub sijhawm tuav txaus tso cai rau lub vuam kom khov thiab ua kom nws lub zog siab tshaj plaws ua ntej tso lub siab.
Factors Influencing Adjustment: Ob peb yam cuam tshuam rau kev hloov kho ntawm lub siab ua ntej, siab, thiab tuav lub sij hawm hauv lub zog cia qhov chaw vuam tshuab. Cov no suav nrog:
- Cov khoom siv ua haujlwm thiab cov tuab: Cov khoom sib txawv thiab cov tuab yuav tsum muaj ntau theem ntawm kev quab yuam thiab lub sijhawm rau kev sib xyaw kom zoo.
- Kev sib koom ua ke: Cov pob qij txha nyuaj lossis sib txawv tuaj yeem xav tau kev hloov kho tshwj xeeb kom ntseeg tau tias cov khoom sib txawv ntawm cov cua sov thiab cov khoom txaus deformation.
- Weld zoo yuav tsum tau: Xav tau lub zog weld, zoo nkauj, thiab cov qauv kev lag luam tshwj xeeb cuam tshuam rau kev xaiv thiab kev hloov kho ntawm cov kev txwv no.
- Lub peev xwm ntawm lub tshuab: Lub tshuab vuam lub zog tso tawm, tswj cov yam ntxwv, thiab cov chaw muaj nyob hauv lub luag haujlwm hauv kev txiav txim siab qhov zoo tshaj plaws rau kev kub siab ua ntej, siab, thiab tuav lub sijhawm.
Kev hloov kho ntawm lub siab ua ntej, siab, thiab tuav lub sijhawm hauv lub zog cia qhov chaw vuam tshuab yog qhov tseem ceeb rau kev ua tiav cov khoom zoo thiab txhim khu kev qha welds. Kev nkag siab txog lub luag haujlwm thiab qhov tseem ceeb ntawm cov kev txwv no, nrog rau cov xwm txheej cuam tshuam rau lawv cov kev hloov kho, tso cai rau cov neeg ua haujlwm ua kom zoo dua cov txheej txheem vuam rau cov khoom sib txawv thiab kev sib koom ua ke. Los ntawm kev ua tib zoo kho lub siab ua ntej, siab, thiab tuav lub sij hawm, cov welders tuaj yeem ua kom cov khoom zoo deformation, muaj zog metallurgical bonds, thiab kev zam ntawm weld defects, uas ua rau cov welds muaj zog thiab ruaj khov.
