Kev suav cov cua sov kom raug yog qhov tseem ceeb hauv cov txiv ntoo vuam tshuab kom ntseeg tau tias kev tswj xyuas kom zoo thaum lub sijhawm vuam. Kev nkag siab txog cov cua sov uas tsim thiab xa tawm yog qhov tseem ceeb rau kev tswj xyuas qhov kev ua haujlwm zoo, tiv thaiv kev kub dhau, thiab ua kom cov welds zoo. Kab lus no muab kev txheeb xyuas ntawm cov qauv ntsuas cua sov siv hauv cov txiv ntoo vuam tshuab, piav qhia lawv qhov tseem ceeb thiab daim ntawv thov hauv kev txiav txim siab qhov ntsuas kub.
- Thaum tshav kub kub Generation: Thaum tshav kub kub nyob rau hauv cov txiv ntseej vuam tshuab tshwm sim feem ntau vim hluav taws xob tsis kam ntawm qhov vuam taw tes. Cov cua sov uas tsim tau tuaj yeem suav nrog cov qauv: Kub (Q) = I^2 * R * t Qhov twg:
- Q yog lub tshav kub tsim (hauv joules lossis watts)
- Kuv yog qhov vuam tam sim no (hauv amperes)
- R yog qhov hluav taws xob tsis kam ntawm qhov chaw vuam (hauv ohms)
- t yog lub sijhawm vuam (hauv vib nas this)
- Thaum tshav kub kub hloov: Thaum tshav kub kub generated thaum vuam yuav tsum tau tswj kom tsis txhob overheating. Kev ntsuas kub hloov pauv pab txiav txim siab qhov yuav tsum tau ua kom sov dissipation. Cov mis hloov hluav taws xob suav nrog kev xav txog yam xws li conduction, convection, thiab hluav taws xob. Nws tuaj yeem qhia tau tias: Q = Q_conduction + Q_convection + Q_radiation Qhov twg:
- Q_conduction sawv cev rau cov cua kub pauv los ntawm kev sib cuag ncaj qha ntawm cov khoom ua haujlwm thiab electrodes.
- Q_convection tso nyiaj rau kev hloov pauv cua sov los ntawm huab cua ib puag ncig lossis cua txias nruab nrab.
- Q_radiation yog hais txog kev hloov hluav taws xob los ntawm hluav taws xob hluav taws xob.
- Cov Lus Qhia Txias Txias: Yuav kom tswj tau qhov ntsuas kub kom zoo, cov cua kub dissipation tus nqi yuav tsum ua kom haum rau cov cua sov tsim. Cov kev xav tau cua txias tuaj yeem suav nrog siv cov qauv: Q_dissipation = Q_generation Qhov twg:
- Q_dissipation yog qhov kub dissipation tus nqi (hauv joules ib ob lossis watts)
- Q_generation yog tus nqi tsim hluav taws xob
Los ntawm kev suav cov cua sov kom raug thiab nkag siab txog cov txheej txheem hloov hluav taws xob, cov neeg ua haujlwm tuaj yeem ua kom muaj kev tswj xyuas cov cua sov hauv cov txiv ntoo vuam tshuab. Qhov no yuav pab tiv thaiv cov khoom siv overheating, optimize weld zoo, thiab txhim khu tag nrho vuam kev ua tau zoo.
Cov qauv ntsuas cua sov ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab tsim hluav taws xob, hloov hluav taws xob, thiab kev xav kom txias hauv cov txiv ntoo vuam tshuab. Los ntawm kev suav thiab tswj cov cua sov kom raug, cov neeg ua haujlwm tuaj yeem ua kom pom kev ua haujlwm zoo, tiv thaiv kev kub dhau, thiab ua tiav cov vuam zoo. Kev nkag siab txog cov qauv no ua rau cov neeg ua haujlwm paub txog kev txiav txim siab txog kev siv vuam, tshuab cua txias, thiab cov txheej txheem cua sov. Thaum kawg, kev tswj cov cua sov kom zoo ua rau kev txhim kho vuam kev ua tau zoo, cov cuab yeej siv tau ntev, thiab txhim kho cov khoom tsim tau zoo hauv cov txheej txheem welding.
