Tiv tauj tsis kam ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim hluav taws xob hauv nruab nrab zaus inverter qhov chaw vuam tshuab. To taub yuav ua li cas cua sov yog tsim los ntawm kev tiv thaiv yog ib qho tseem ceeb rau optimizing lub vuam txheej txheem thiab ua tau zoo welds. Kab lus no muab cov ntsiab lus ntawm cov txheej txheem koom nrog hauv kev tsim hluav taws xob los ntawm kev tiv thaiv kev tiv thaiv hauv nruab nrab zaus inverter chaw vuam tshuab.
- Kev Tiv Thaiv Kev Tiv Thaiv: Kev tiv thaiv tiv thaiv tshwm sim ntawm qhov sib cuam tshuam ntawm cov electrodes thiab cov khoom ua haujlwm thaum vuam. Nws yog tshwm sim los ntawm kev sib cuag tsis zoo ntawm cov lus qhia electrode thiab cov chaw ua haujlwm. Kev tiv thaiv kev tiv thaiv nyob ntawm ntau yam, suav nrog qhov roughness ntawm qhov chaw, huv si, thov siab, thiab hluav taws xob conductivity ntawm cov ntaub ntawv.
- Joule Cua sov: Thaum hluav taws xob tam sim no dhau los ntawm kev sib cuag nrog kev tiv thaiv, nws ua rau Joule cua sov. Raws li Ohm txoj cai, lub tshav kub tsim yog proportional rau lub square ntawm tam sim no thiab kev sib cuag tsis kam. Qhov siab dua qhov tam sim no thiab kev tiv thaiv, qhov kub ntau yog tsim.
- Thaum tshav kub kub Distribution: Thaum tshav kub kub generated los ntawm kev sib cuag tsis kam yog feem ntau concentrated nyob rau hauv kev sib cuag interface ntawm electrodes thiab workpieces. Cov cua sov hauv cheeb tsam ua rau qhov kub thiab txias nce nyob rau thaj tsam tam sim ntawm qhov chaw sib cuag, ua rau tsim cov molten nugget thiab tom qab fusion ntawm cov khoom siv ua haujlwm.
- Thermal conductivity: Cov hluav taws xob generated yog kis los ntawm kev sib cuag mus rau hauv cov ntaub ntawv nyob ib puag ncig los ntawm thermal conduction. Lub thermal conductivity ntawm workpieces plays lub luag haujlwm tseem ceeb hauv kev faib thiab dissipating cua sov. Kev hloov pauv hluav taws xob ua kom zoo ua kom zoo fusion thiab txo qhov kev pheej hmoo ntawm thermal puas rau thaj chaw ib puag ncig.
- Kev Tswj Thaum Kub Kub: Kev tswj cov cua sov uas tsim los ntawm kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb rau kev ua tiav zoo ib yam thiab zoo welds. Cov hluav taws xob hluav taws xob tuaj yeem hloov kho los ntawm kev tswj cov vuam tsis xws li vuam tam sim no, lub sijhawm vuam, lub zog electrode, thiab cov khoom siv electrode. Optimizing cov kev txwv no pab tswj cov cua sov tsim, tiv thaiv overheating lossis cua sov tsis txaus.
Thaum tshav kub kub tsim los ntawm kev tiv thaiv tiv thaiv yog ib qho tseem ceeb ntawm cov txheej txheem vuam nyob rau hauv nruab nrab zaus inverter chaw vuam tshuab. Kev tiv thaiv kev tiv thaiv, cuam tshuam los ntawm cov xwm txheej xws li cov xwm txheej saum npoo thiab siv siab, ua rau Joule cua sov ntawm qhov sib cuam tshuam ntawm cov electrodes thiab cov khoom ua haujlwm. Thaum tshav kub kub yog concentrated nyob rau hauv lub cheeb tsam, uas ua rau lub zos melting thiab fusion. Kev tswj cov cua sov kom zoo los ntawm kev ua kom zoo tshaj plaws ntawm cov vuam tsis ua kom lub cim ntawm cov cua sov txaus rau vuam yam tsis ua rau muaj kev puas tsuaj ntau dhau. Kev nkag siab txog cov txheej txheem koom nrog hauv kev tsim hluav taws xob los ntawm kev tiv thaiv kev tiv thaiv yuav pab txhim kho cov txheej txheem vuam thiab ua tiav cov welds txhim khu kev qha thiab zoo hauv ntau daim ntawv thov.
