Nruab nrab zaus qhov chaw vuam tshuab ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim khoom niaj hnub no.Kev nkag siab txog cov ntsiab lus ntawm kev tsis sib haum xeeb thiab kev nkhaus tam sim no yog qhov tseem ceeb rau kev ua kom zoo dua vuam cov txiaj ntsig thiab ua kom muaj qhov zoo sib xws.Kab lus no delves rau hauv qhov tseem ceeb ntawm kev ua haujlwm tsis zoo thiab cov nkhaus tam sim no hauv nruab nrab zaus qhov chaw vuam tshuab thiab lawv qhov cuam tshuam rau cov txheej txheem vuam.
Dynamic Resistance:Dynamic resistance yog hais txog qhov kev tawm tsam uas tau ntsib los ntawm lub tshuab vuam thaum lub sij hawm vuam txheej txheem.Tsis zoo li static resistance, uas tseem nyob tas li, dynamic kuj txawv raws li cov workpieces raug coj mus rau hauv kev sib cuag thiab raug rau siab.Nws yog cuam tshuam los ntawm cov khoom xws li cov khoom siv ntawm cov khoom ua haujlwm, lub zog electrode, thiab qhov chaw sib cuag ntawm cov electrodes thiab cov khoom ua haujlwm.
Curve tam sim no:Qhov nkhaus tam sim no yog cov duab sawv cev ntawm cov welding tam sim no tus cwj pwm thaum lub sij hawm vuam txheej txheem.Nws muab kev nkag siab txog kev ua haujlwm ntawm kev ua haujlwm vuam, suav nrog kev pib ua haujlwm tam sim no raws li cov electrodes tsim kev sib cuag thiab kev ruaj khov tom ntej raws li kev sib txuas.Qhov nkhaus tam sim no tuaj yeem nthuav tawm qhov tsis xws li qhov hloov pauv, qhov sib txawv, lossis qhov tsis sib xws hauv cov vuam tam sim no, pab cov neeg ua haujlwm kuaj xyuas cov teeb meem muaj peev xwm.
Qhov tseem ceeb ntawm Dynamic Resistance thiab Current Curve:
1. Weld Quality Assessment:Kev soj ntsuam qhov kev ua haujlwm tsis zoo thiab qhov nkhaus tam sim no tso cai rau cov neeg ua haujlwm los ntsuas qhov zoo ntawm qhov vuam.Sudden spikes los yog tee nyob rau hauv tsis kam los yog tam sim no qhia tau hais tias irregularities nyob rau hauv lub vuam txheej txheem, xws li tsis zoo electrode tiv tauj los yog cov khoom inconsistencies.
2. Txheej txheem Optimization:Kev txheeb xyuas qhov nkhaus tam sim no pab txhawm rau txhim kho cov txheej txheem vuam, xws li electrode quab yuam thiab vuam tam sim no.Los ntawm kev nkag siab txog qhov kev hloov pauv tam sim no li cas thaum lub sijhawm sib txawv ntawm vuam, cov neeg ua haujlwm tuaj yeem kho qhov teeb tsa kom zoo dua qub thiab zoo li qub.
3. Kev kuaj pom tsis zoo:Kev sib txawv ntawm qhov kev xav tau tam sim no tuaj yeem qhia txog cov teeb meem muaj peev xwm, xws li electrode contamination, misalignment, lossis cov khoom tsis xws luag.Kev tshawb pom ntxov ntawm cov kev tsis txaus ntseeg no tso cai rau kev kho kom raug raws sijhawm.
4. Kev saib xyuas lub sijhawm tiag tiag:Niaj hnub nimno nruab nrab zaus qhov chaw vuam tshuab feem ntau muaj lub sijhawm saib xyuas lub sijhawm uas tso saib cov dynamic tsis kam thiab nkhaus tam sim no thaum vuam.Qhov no tso cai rau cov neeg ua haujlwm hloov kho ntawm qhov chaw thiab xyuas kom muaj qhov zoo sib xws.
Dynamic tsis kam thiab cov nkhaus tam sim no ua lub luag haujlwm tseem ceeb hauv kev nkag siab tus cwj pwm ntawm qhov nruab nrab zaus qhov chaw vuam tshuab thaum lub sijhawm vuam.Cov ntsiab lus no muab kev nkag siab zoo rau kev ua haujlwm ntawm kev ua haujlwm vuam, pab ntsuas qhov zoo ntawm qhov vuam, thiab pab hauv kev ua kom zoo dua.Los ntawm kev ua tib zoo saib xyuas kev ua haujlwm tsis zoo thiab cov nkhaus tam sim no, cov neeg ua haujlwm tuaj yeem txhim kho cov txiaj ntsig ntawm vuam thiab tuav cov qauv zoo tshaj plaws ntawm cov khoom siv vuam zoo hauv kev lag luam.
