Vuam tsis ua lub luag haujlwm tseem ceeb hauv cov tshuab vuam pob tw, vim lawv txhais cov kev teeb tsa tshwj xeeb yuav tsum ua kom tau txais txiaj ntsig zoo vuam. Kev nkag siab txog cov kev txwv no thiab lawv qhov tseem ceeb yog qhov tseem ceeb rau cov neeg siv khoom thiab cov kws tshaj lij hauv kev lag luam vuam. Qhov tsab xov xwm no tshawb txog cov vuam tsis nyob rau hauv lub taub qab vuam tshuab vuam specifications, hais txog lawv lub luag hauj lwm los xyuas kom meej meej thiab zoo welds.
- Lub ntsiab lus ntawm Vuam Parameters: Vuam tsis yog hais txog cov txheej txheem tshwj xeeb uas tswj cov txheej txheem vuam hauv lub tshuab taub qab vuam. Cov tsis muaj xws li vuam tam sim no, voltage, xaim pub ceev, preheating kub, thiab interpass kub, thiab lwm yam.
- Vuam tam sim no thiab qhov hluav taws xob: Vuam tam sim no thiab qhov hluav taws xob yog qhov tseem ceeb uas txiav txim siab cov cua sov nkag mus rau qhov sib koom ua ke. Kev tswj kom zoo ntawm cov txiaj ntsig no ua kom muaj txiaj ntsig zoo ntawm cov cua sov uas yuav tsum tau ua kom zoo fusion thiab weld nkag mus.
- Hlau Feed Ceev: Cov xov hlau pub ceev dictates tus nqi ntawm cov vuam electrode yog pub rau hauv qhov sib koom ua ke. Kho cov xaim pub ceev yog qhov tseem ceeb rau kev tswj xyuas qhov ruaj khov arc thiab ua tiav cov khoom siv weld hlaws.
- Preheating kub: Preheating kub yog qhov kub ntawm lub hauv paus hlau yog rhuab ua ntej vuam. Nws yog ib qho tseem ceeb rau kev tiv thaiv kev tawg thiab txo kev pheej hmoo ntawm hydrogen-induced defects.
- Interpass Temperature: Interpass kub yog hais txog qhov kub ntawm lub hauv paus hlau ntawm qhov txuas txuas txuas mus ntxiv. Kev tswj qhov kub ntawm qhov sib cuam tshuam yog qhov tseem ceeb rau kev txo qis qhov kev pheej hmoo ntawm cov teeb meem kub kub thiab ua kom muaj kev sib xyaw ua ke ntawm kev hla dhau.
- Shielding Gas Flow Rate: Hauv cov txheej txheem uas siv cov khoom siv tiv thaiv, xws li MIG lossis TIG welding, qhov thaiv cov roj ntws tawm yog qhov tseem ceeb heev. Cov pa roj kom zoo ua kom muaj kev tiv thaiv txaus ntawm lub pas dej ua ke los ntawm kev sib kis atmospheric.
- Joint Design thiab Fit-Up: Kev sib koom tsim thiab kev sib haum xeeb yog qhov tseem ceeb rau cov tshuab vuam taub qab. Ib qho kev sib koom ua ke zoo nrog kev sib haum xeeb kom ntseeg tau tias kev sib txuas zoo sib xws thiab kev sib raug zoo.
- Kev kho cua sov tom qab vuam (PWHT): Rau cov ntaub ntawv tshwj xeeb thiab kev siv, kev kho cua sov tom qab vuam yuav raug teev nyob rau hauv cov kev ntsuas vuam. PWHT pab txo qis kev ntxhov siab thiab txhim kho cov khoom siv vuam.
Nyob rau hauv xaus, welding tsis yog ib qho tseem ceeb nyob rau hauv lub pob tw welding tshuab vuam specifications, dictating cov chaw yuav tsum tau rau kev vam meej vuam hauj lwm. Vuam tam sim no, voltage, xaim pub ceev, preheating kub, interpass kub, shielding roj txaus tus nqi, sib koom tsim, haum-up, thiab tom qab-weld kev kho cua sov yog qhov tseem ceeb tsis zoo uas ua rau weld zoo thiab kev ncaj ncees. Los ntawm kev mob siab rau kev ua raws li cov kev qhia tshwj xeeb ntawm vuam thiab ua tib zoo tswj cov kev txwv no, cov welds thiab cov kws tshaj lij tuaj yeem ua tiav cov vuam zoo thiab zoo hauv ntau yam kev siv thiab kev lag luam. Kev hais txog qhov tseem ceeb ntawm cov vuam tsis ua kom zoo ntawm lub pob tw vuam tshuab ua haujlwm, ua rau muaj kev nyab xeeb thiab txhim khu kev qha hlau sib koom ua haujlwm.
