Kev tshuaj xyuas txoj hauv kev rau Kev Tswj Xyuas Zoo hauv Nruab Nrab-Frequency Inverter Spot Vuam

Ua kom ntseeg tau qhov zoo ntawm qhov chaw vuam yog qhov tseem ceeb hauv kev tsim khoom lag luam, thiab kev ua haujlwm ntawm qhov nruab nrab zaus inverter qhov chaw vuam tshuab ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov zoo sib xws. Yuav kom tswj tau cov qauv vuam uas xav tau, nws yog ib qho tseem ceeb rau kev siv cov txheej txheem tshuaj xyuas zoo uas tuaj yeem ntsuas qhov zoo ntawm qhov chaw welds. Hauv tsab xov xwm no, peb yuav tham txog ntau txoj hauv kev tshuaj xyuas feem ntau siv los ntsuas qhov vuam zoo ntawm nruab nrab zaus inverter qhov chaw vuam tshuab.

1. Visual Inspection: Kev kuaj pom pom yog ib txoj hauv kev los ntsuas qhov chaw weld zoo. Nws cuam tshuam rau qhov pom ntawm qhov chaw vuam rau qhov tsis xws luag xws li cov kab nrib pleb, porosity, tsis tiav fusion, lossis ntau dhau spatter. Cov cuab yeej teeb pom kev zoo thiab kev nthuav dav tuaj yeem pab txhawm rau txheeb xyuas qhov tsis zoo uas yuav cuam tshuam rau lub vuam lub zog thiab kev ncaj ncees.
2. Kev kuaj kev puas tsuaj: Kev kuaj kev puas tsuaj suav nrog kev tshuaj xyuas lub cev thiab ntsuas qhov sib koom ua ke los ntsuas nws lub zog thiab kev ncaj ncees ntawm cov qauv. Txoj kev no suav nrog ntau yam txuj ci xws li kev sim tensile, kuaj khoov, thiab kev tshuaj xyuas microstructural. Kev kuaj kev puas tsuaj muab cov ntaub ntawv ntau ntawm cov khoom siv vuam vuam, nrog rau qhov kawg tensile lub zog, elongation, thiab tawg toughness.
3. Kev Ntsuam Xyuas Tsis Zoo: Cov kev kuaj tsis yog kev puas tsuaj (NDT) yog siv los ntsuas qhov chaw vuam zoo yam tsis muaj kev puas tsuaj rau qhov sib koom ua ke. Cov txheej txheem NDT feem ntau suav nrog kev kuaj ultrasonic, kuaj hluav taws xob, kuaj tam sim no, thiab tshuaj xyuas cov khoom sib nqus. Cov txheej txheem no tuaj yeem txheeb xyuas qhov tsis xws li cov voids sab hauv, tawg, lossis tsis tiav fusion nyob rau hauv qhov chaw vuam.
4. Kev ntsuas hluav taws xob tsis zoo: Kev ntsuas hluav taws xob tiv thaiv yog ib txoj hauv kev uas tsis muaj kev puas tsuaj uas ntsuas qhov chaw vuam zoo raws li qhov tsis kam ntawm qhov sib koom ua ke. Los ntawm kev ntsuas qhov hluav taws xob tsis kam, nws tuaj yeem txheeb xyuas qhov txawv ntawm qhov zoo ntawm cov khoom siv, xws li kev tsim tsis txaus lossis tsis sib haum xeeb ntawm cov electrodes thiab workpieces. Kev ntsuas kev tiv thaiv tuaj yeem ua tau siv cov cuab yeej tshwj xeeb tsim los rau lub hom phiaj no.
5. Cross-Sectional Analysis: Kev txheeb xyuas hla ntu suav nrog kev txiav thiab npaj cov qauv tus neeg sawv cev ntawm qhov chaw vuam rau kev tshuaj xyuas microscopic. Txoj kev no tso cai rau kev soj ntsuam ntxaws ntxaws ntawm cov weld's microstructure, suav nrog nugget loj, fusion zone, tshav kub cuam tshuam, thiab tej yam tsis xws luag. Kev soj ntsuam hla ntu muab kev nkag siab tseem ceeb rau hauv qhov weld tus yam ntxwv metallurgical thiab pab txheeb xyuas cov teeb meem cuam tshuam rau qhov zoo ntawm vuam.

Ua raws li txoj kev tshuaj xyuas zoo yog qhov tseem ceeb rau kev ua kom cov vuam zoo ntawm nruab nrab zaus inverter chaw vuam tshuab. Kev tshuaj xyuas qhov muag, kev ntsuam xyuas kev puas tsuaj, kev sim tsis muaj kev puas tsuaj, kev ntsuas hluav taws xob tiv thaiv, thiab kev txheeb xyuas qhov sib txawv yog cov kev siv feem ntau los ntsuas qhov chaw weld zoo. Los ntawm kev siv cov txheej txheem tshuaj ntsuam xyuas no, cov tuam txhab tsim khoom tuaj yeem txheeb xyuas qhov tsis xws ntawm vuam, ntsuas qhov ncaj ncees ntawm vuam, thiab ua qhov tsim nyog hloov kho kom zoo dua cov txheej txheem vuam. Kev siv cov txheej txheem tshuaj xyuas no yuav ua rau muaj kev txhim kho weld zoo, txhim kho cov khoom ntseeg tau, thiab muaj kev txaus siab rau cov neeg siv khoom.
