Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog qhov tseem ceeb ntawm cov vuam tsis zoo ntawm lub taub qab vuam tshuab, uas ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov tseeb thiab zoo welds. Kev nkag siab txog cov kev txwv no yog qhov tseem ceeb rau cov welders thiab cov tswv lag luam txhawm rau txhim kho cov txheej txheem vuam thiab ua kom cov txiaj ntsig tau zoo hauv ntau yam kev siv vuam.
Taw qhia: Kev ua tau zoo thiab kev ua tau zoo ntawm lub taub qab vuam tshuab cia siab rau nws cov vuam tsis zoo. Cov kev ntsuas no txiav txim siab qhov vuam cov yam ntxwv, xws li kev nkag mus tob, fusion zone, thiab tag nrho qhov zoo. Kev paub txog cov kev txwv no txhawb cov neeg ua haujlwm welding los kho cov txheej txheem vuam kom ua tau raws li qhov kev xav tau tshwj xeeb thiab ua tiav cov welds zoo dua.
- Vuam tam sim no: Vuam tam sim no, ntsuas hauv amperes (A), yog ib qho tseem ceeb tshaj plaws vuam tsis. Nws txiav txim siab npaum li cas ntawm cov cua sov tsim thaum lub sij hawm welding txheej txheem, cuam tshuam cov weld qhov nkag thiab fusion yam ntxwv. Cov qib siab tam sim no ua rau kev nkag mus tob dua, thaum cov qib qis ua rau cov welds ntiav.
- Vuam Voltage: Vuam voltage, ntsuas nyob rau hauv volts (V), txiav txim siab lub arc ntev thiab kub concentration ntawm lub vuam sib txuas. Nws ncaj qha cuam tshuam qhov dav thiab cov duab ntawm cov hlaws weld. Kho qhov vuam voltage pab tswj cov hlaws qhov loj thiab qhov tob tob.
- Vuam Lub Sijhawm: Lub sijhawm vuam, ntsuas hauv vib nas this (s), hais txog lub sijhawm ntawm cov txheej txheem vuam. Nws cuam tshuam rau tag nrho cov cua kub nkag thiab fusion cheeb tsam dav. Lub sij hawm vuam tsim nyog ua kom muaj fusion txaus ntawm cov ntaub ntawv hauv paus.
- Vuam ceev: Vuam ceev, ntsuas nyob rau hauv centimeters ib feeb (cm / min), yog hais txog tus nqi uas lub vuam torch mus raws qhov sib koom ua ke. Kev tswj cov vuam ceev yog qhov tseem ceeb rau kev tswj xyuas cov khoom siv hluav taws xob zoo ib yam thiab cov hlaws zoo.
- Electrode Siab: Electrode siab, ntsuas hauv kilograms-force (kgf), sawv cev rau lub zog siv los ntawm lub tshuab vuam los tuav cov khoom ua haujlwm ua ke thaum vuam. Kev siv hluav taws xob zoo yog qhov tseem ceeb rau kev ua tiav cov welds muaj zog thiab tsis sib xws.
- Preheating: Preheating yog qhov kev xyaum ua kom lub hauv paus hlau qhov kub thiab txias ua ntej vuam. Nws pab txo cov vuam tawg thiab kev ntxhov siab hauv cov ntaub ntawv muaj zog los yog tuab. Lub preheating kub thiab lub sij hawm nyob ntawm seb lub hauv paus hlau muaj pes tsawg leeg thiab thickness.
Mastering lub vuam tsis zoo ntawm lub taub qab vuam tshuab yog qhov tseem ceeb rau cov welds nrhiav los tsim cov khoom zoo welds tsis tu ncua. Los ntawm kev nkag siab thiab ua kom zoo dua vuam tam sim no, vuam voltage, vuam lub sij hawm, vuam ceev, electrode siab, thiab preheating, cov neeg ua haujlwm tuaj yeem kho cov txheej txheem vuam kom haum rau cov kev siv tshwj xeeb thiab ua tiav cov txiaj ntsig zoo. Kev ntsuas qhov tseeb ua rau muaj zog, txhim khu kev qha, thiab tsis muaj qhov tsis xws luag, ua rau lub taub qab vuam tshuab yog ib qho cuab yeej tseem ceeb hauv ntau yam kev lag luam, suav nrog kev tsim kho, kev tsim, thiab kev lag luam tsheb.
