Dab tsi qhov chaw vuam tshuab siv rau vuam aluminium alloys?

Thaum welding aluminium alloys, cov kev xaiv thaum ntxov feem ntau suav nrog peb-theem theem nrab rectificationchaw vuam tshuabthiab lub zog cia chaw vuam tshuab. Cov tshuab no raug xaiv vim tias txhuas alloys muaj hluav taws xob zoo thiab thermal conductivity.

Cov pa AC qhov chaw vuam tshuab feem ntau tsis muaj txiaj ntsig ntawm qhov cua sov ntawm qhov chaw vuam mus rau lub xeev melting lossis yas los ua ib qho vuam nugget. Tsis tas li ntawd, cov khoom siv aluminium yog qhov yooj yim rau kev tsim cov oxide zaj duab xis. Lub melting point ntawm txhuas oxide yog ntau dua (ze li 2000 degrees) piv rau txhuas lub melting point ntawm 660 degrees. Yog li ntawd, kev rhuav tshem cov oxide txheej zoo thiab cua sov lub vuam nugget ua qhov tseem ceeb hauv kev xaiv lub tshuab aluminium alloy qhov chaw vuam tshuab.

Raws li Joule txoj cai lij choj Q = I²Rt, vim yog cov hluav taws xob hluav taws xob siab thiab cov ntaub ntawv zoo nkauj ntawm cov hlau nplaum, cov tshuab vuam yuav tsum muaj cov zis loj tam sim no, kev ua haujlwm siab thermal, thiab tsis tshua muaj siab. Tsis zoo li cov lus qhia tshwj xeeb, aluminium alloy qhov chaw vuam tsis tuaj yeem siv lub sijhawm vuam ntev dua, tab sis yuav tsum muaj lub sijhawm luv luv nrog tam sim no dua.

Nrog rau kev taw qhia ntawm nruab nrab zaus inverter DC chaw vuam tshuab, lawv cov yam ntxwv ntawm tag nrho-yoj rectification thiab cov zis ncaj qha tam sim no tau txhim kho cov thermal efficiency thiab nkag mus rau hauv qhov chaw vuam. Qhov no yog qhov sib piv rau qhov tsis txaus ntawm ib nrab-yoj rectification nyob rau hauv peb-theem theem nrab rectification tshuab thiab lub sij hawm tawm ntawm lub zog cia cov cav tov. Txij li thaum cov tsos ntawm nruab nrab zaus inverter DC chaw vuam tshuab, lawv tau sai sai ua qhov kev xaiv zoo tshaj plaws rau vuam aluminium alloys.

Cia kuv qhia rau koj, vim nws qhov sib npaug peb-theem fais fab mov, cov zis ncaj qha tam sim no, thiab lub sijhawm vuam tswj tau, qhov nruab nrab zaus inverter DC qhov chaw vuam tshuab yog qhov kev xaiv zoo tshaj plaws rau vuam aluminium alloys.
