Qhov zoo ntawm welded pob qij txha tsim los ntawm nruab nrab zaus inverter qhov chaw vuam tshuab yog qhov tseem ceeb rau kev ua kom muaj kev ncaj ncees thiab kev ua haujlwm ntawm ntau yam khoom. Txhawm rau kom ua tiav cov welds zoo ib yam thiab txhim khu kev qha, nws yog ib qho tseem ceeb rau kev siv cov txheej txheem kev soj ntsuam zoo. Kab lus no muab cov ntsiab lus dav dav ntawm kev saib xyuas cov txheej txheem siv los ntsuas qhov zoo ntawm cov pob qij txha welded hauv nruab nrab zaus inverter qhov chaw vuam tshuab.
- Kev soj ntsuam pom pom: Kev kuaj pom pom yog cov txheej txheem tseem ceeb rau kev ntsuas qhov zoo ntawm cov pob qij txha welded. Cov neeg ua haujlwm pom qhov muag tshuaj xyuas qhov chaw vuam los txheeb xyuas qhov tsis xws luag xws li kev ua tsis tiav, kev sib tsoo ntau dhau, tawg, lossis tsim tsis tsim nyog. Kev kuaj pom pom tuaj yeem ua tau siv cov cuab yeej magnification, xws li microscopes lossis borescopes, txhawm rau txhim kho kev soj ntsuam ntawm qhov sib txawv lossis nyuaj rau kev ncav cuag welds.
- Cov Kev Ntsuas Tsis Zoo (NDT) Cov Txheej Txheem: Cov txheej txheem kev kuaj tsis muaj kev puas tsuaj ua lub luag haujlwm tseem ceeb hauv kev ntsuas qhov kev ncaj ncees sab hauv thiab saum npoo ntawm cov pob qij txha welded yam tsis muaj kev puas tsuaj. Qee cov kev siv NDT feem ntau siv rau kev saib xyuas zoo hauv nruab nrab zaus inverter qhov chaw vuam tshuab suav nrog:
- Ultrasonic Testing (UT): UT siv lub suab nrov zaus los kuaj xyuas qhov tsis xws luag xws li tsis muaj fusion, porosity, lossis tawg hauv qhov sib koom ua ke. Cov nthwv dej uas muaj kev cuam tshuam raug tshuaj xyuas los txiav txim qhov loj, cov duab, thiab qhov chaw ntawm qhov tsis xws luag.
- Radiographic Testing (RT): RT suav nrog kev siv X-rays lossis gamma rays los tsim cov duab ntawm qhov sib koom ua ke. Nws tso cai rau kev txheeb xyuas cov teeb meem sab hauv, xws li suav nrog, voids, lossis misalignment. Cov duab hluav taws xob tuaj yeem muab cov ncauj lus kom ntxaws txog cov vuam zoo thiab kev ncaj ncees.
- Magnetic Particle Testing (MT): MT feem ntau yog siv rau cov ntaub ntawv ferromagnetic. Cov txheej txheem muaj xws li daim ntawv thov ntawm magnetic teb thiab siv cov khoom sib nqus. Txhua qhov kev puas tsuaj ntawm qhov chaw, xws li cov kab nrib pleb lossis laps, cuam tshuam cov hlau nplaum, ua rau cov khoom sib sau ntawm qhov chaw tsis raug thiab pom tau.
- Dye Penetrant Testing (PT): PT yog qhov tsim nyog rau kev kuaj xyuas qhov tsis xws luag hauv cov khoom tsis ntxeem tau. Cov txheej txheem suav nrog kev siv cov xim dye rau saum npoo, tso cai rau nws nkag mus rau txhua qhov chaw tawg. Cov xim ntau dhau raug tshem tawm, thiab tus tsim tawm yog siv los txhim kho qhov pom ntawm qhov tsis xws luag.
- Mechanical Testing: Mechanical test method yog siv los ntsuas cov khoom siv kho tshuab thiab lub zog ntawm cov pob qij txha welded. Qee cov txheej txheem uas muaj xws li:
- Kev Ntsuas Tensile: Kev ntsuas Tensile suav nrog kev siv lub zog tensile rau qhov sib koom ua ke kom txog thaum nws tawg. Qhov kev sim no pab txiav txim siab qhov sib koom ua ke qhov kawg tensile lub zog, tawm lub zog, thiab elongation, muab kev nkag siab rau nws cov neeg kho tshuab kev ncaj ncees.
- Hardness Testing: Kev ntsuas hardness ntsuas qhov hardness ntawm cov welded sib koom siv cov cuab yeej tshwj xeeb, xws li hardness tester. Nws muab ib qho kev qhia txog kev sib koom ua ke lub zog thiab ua haujlwm rau deformation.
- In-Process Monitoring: Cov txheej txheem kev soj ntsuam hauv txheej txheem tso cai rau kev ntsuam xyuas lub sijhawm ntawm cov vuam tsis zoo thiab cov ntsuas ntsuas zoo thaum lub sijhawm ua haujlwm vuam. Cov txheej txheem no feem ntau koom nrog kev siv cov sensors lossis cov tshuab saib xyuas los ntes thiab txheeb xyuas cov ntaub ntawv ntsig txog tam sim no, voltage, kub, lossis quab yuam. Cov kev sib txawv ntawm cov qauv tsim los yog cov txheej txheem ua ntej tuaj yeem ua rau muaj kev ceeb toom lossis kev hloov kho tsis siv neeg kom tswj tau qhov zoo sib xws.
Kev soj ntsuam xyuas cov txheej txheem zoo yog qhov tseem ceeb rau kev ua kom ntseeg tau thiab kev ua haujlwm ntawm cov pob qij txha uas ua los ntawm nruab nrab zaus inverter qhov chaw vuam tshuab. Los ntawm kev sib koom ua ke kev tshuaj xyuas qhov muag, kev sim tsis muaj kev puas tsuaj, kev sim tshuab, thiab kev soj ntsuam hauv cov txheej txheem, cov tuam ntxhab tuaj yeem ntsuas qhov zoo ntawm cov welds. Cov txheej txheem no ua kom pom qhov tsis xws luag thaum ntxov, kom ntseeg tau tias kev kho kom raug tuaj yeem ua sai sai kom tswj tau cov welds zoo thiab ua tau raws li cov qauv xav tau. Ua raws li cov txheej txheem kev soj ntsuam zoo txhim kho tag nrho cov txiaj ntsig thiab kev ua tau zoo ntawm nruab nrab zaus inverter chaw vuam tshuab, ua
