Tom qab Weld Inspection hauv Txiv Ntoo Projection Vuam?

Tom qab ua tiav cov noob txiv qhov projection welding, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo soj ntsuam xyuas qhov zoo ntawm qhov vuam thiab xyuas kom nws ua tau raws li cov qauv xav tau.Kab lus no tsom mus rau cov txheej txheem tshuaj xyuas thiab cov txheej txheem uas feem ntau ua haujlwm los ntsuas qhov kev ncaj ncees ntawm cov txiv ntoo projection welding.

1. Kev soj ntsuam pom pom: Kev kuaj pom pom yog thawj thiab yooj yim tshaj plaws los ntsuas qhov zoo ntawm qhov vuam.Nws suav nrog kev tshuaj xyuas qhov muag ntawm thaj chaw weld kom pom qhov tsis xws luag xws li tawg, voids, lossis tsis tiav fusion.Tus neeg teb xov tooj tshuaj xyuas qhov chaw ntawm qhov sib koom ua ke, ua tib zoo saib xyuas cov duab thiab qhov loj ntawm qhov nugget, muaj qhov tsis sib xws, thiab tag nrho cov tsos ntawm cov vuam.
2. Dimensional Inspection: Dimensional soj ntsuam yuav ntsuas qhov ntev ntawm qhov sib koom ua ke kom paub tseeb tias nws ua tau raws li qhov kev cia siab.Qhov no suav nrog ntsuas txoj kab uas hla thiab qhov siab ntawm weld nugget, qhov projection qhov siab, thiab tag nrho cov geometry ntawm qhov sib koom ua ke.Cov kev ntsuas tau muab piv rau qhov yuav tsum tau muaj qhov ntev kom ntseeg tau tias kev tsim cov vuam zoo.
3. Non-Destructive Testing (NDT): Cov txheej txheem kuaj tsis muaj kev puas tsuaj tuaj yeem muab cov ntaub ntawv tseem ceeb txog kev ncaj ncees sab hauv ntawm vuam yam tsis ua rau muaj kev puas tsuaj rau kev sib koom ua ke.Feem ntau NDT txoj kev siv hauv cov txiv ntoo projection vuam suav nrog:
   • Kev Ntsuas Ultrasonic (UT): Ultrasonic nthwv dej yog siv los kuaj xyuas qhov tsis xws luag xws li tawg lossis voids hauv qhov sib koom ua ke.
   • Radiographic Testing (RT): X-rays lossis gamma rays yog siv los tsim cov duab ntawm cov vuam, tso cai rau kev kuaj pom ntawm qhov tsis xws luag lossis tsis tiav fusion.
   • Sib Nqus Particle Testing (MT): Cov khoom sib nqus tau siv rau saum npoo ntawm qhov vuam, thiab txhua qhov sib nqus nqus los ntawm qhov tsis xws luag raug kuaj pom siv cov khoom sib nqus.
   • Dye Penetrant Testing (PT): Ib qho dye penetrant yog siv rau ntawm qhov chaw ntawm qhov vuam, thiab txhua qhov kev puas tsuaj ntawm qhov chaw raug nthuav tawm los ntawm cov xim nkag mus rau hauv qhov tsis xws luag.
4. Mechanical Testing : Mechanical testing with subjecting the weld joint to various mechanical tests los soj ntsuam nws lub zog thiab kev ncaj ncees.Qhov no tuaj yeem suav nrog kev sim tensile, qhov twg cov vuam tau raug tswj kom rub lub zog los ntsuas nws qhov tsis kam rau kev sib cais.Lwm qhov kev ntsuam xyuas xws li kev sim khoov lossis kev sim hardness kuj tseem tuaj yeem muab cov ntaub ntawv tseem ceeb txog cov khoom siv vuam vuam.

Kev soj ntsuam tom qab vuam hauv cov txiv ntoo projection welding plays lub luag haujlwm tseem ceeb hauv kev ua kom zoo thiab kev ncaj ncees ntawm cov pob qij txha.Los ntawm kev siv kev tshuaj xyuas qhov muag, kev tshuaj xyuas qhov ntev, kev sim tsis muaj kev puas tsuaj, thiab cov txheej txheem kev sim tshuab, cov neeg ua haujlwm tuaj yeem txheeb xyuas qhov teeb meem lossis qhov tsis sib xws thiab ua raws li qhov tsim nyog.Qhov no pab tswj kev ntseeg tau thiab kev ua tau zoo ntawm cov pob qij txha, kom ntseeg tau tias lawv ua tau raws li cov qauv thiab cov kev qhia tshwj xeeb.
