Dab tsi yog qhov tseem ceeb ntawm cov cuab yeej ntsuas kub hauv cov txheej txheem vuam?

Qhov ntsuas kub ntsuas yog qhov tseem ceeb tshaj plaws hauv cov txheej txheem vuam. Thaum nws koom nrog cov thermocouples, lawv tau txais qhov tseem ceeb ntawm cov ntsiab lus no.
Saib xyuas qhov kub thiab txias. Nyob rau hauv welding, qhov kub ntawm qhov chaw weld yog ib qho tseem ceeb rau kom muaj txoj cai weld. Cov cuab yeej ntsuas kub, uas suav nrog cov thermocouples, tuaj yeem siv los tshuaj xyuas qhov ntsuas kub ntawm qee qhov ntawm qhov vuam. Qhov no tso cai rau kom paub tseeb tias cov vuam yog tsim los ntawm qhov kub thiab txias ntau yam rau cov hluav taws xob zoo tshaj plaws thiab thawj-chav kawm. Thermocouples tuaj yeem txuas rau thaj tsam weld lossis nyob ze ze rau nws kom muaj qhov ntsuas kub kom raug. Los ntawm kev taug qab qhov kub ntawm qhov vuam, kev hloov pauv tuaj yeem ua rau cov vuam tsis sib xws nrog rau tam sim no, qhov hluav taws xob, thiab qhov nrawm kom khaws cia qhov kub siab.
Ntsuas preheating thiab tom qab-weld warmness kho. Preheating thiab tom qab-weld warmness kho yuav tsum tsis tu ncua nyob rau hauv vuam kom txuag koj cracking thiab txhim khu cov neeg kho tshuab qhov chaw ntawm lub vuam. Cov cuab yeej ntsuas kub yog siv los tshuaj xyuas qhov ntsuas kub ntawm qee qhov ntawm cov txheej txheem. Thermocouples tuaj yeem siv los ntsuas qhov ntsuas kub ntawm cov hlau hauv qab ua ntej thiab tom qab vuam thiab ntawm qee qhov kev kho kom sov. Qhov no tso cai rau kom paub tseeb tias qhov preheating thiab post-weld warmness kho tau raug tua ntawm qhov kub thiab txias rau lub sijhawm. Los ntawm kev taug qab cov ntsuas kub, qhov kev ncaj ncees thiab ruaj khov ntawm cov vuam yuav raug txhim kho.
Tshawb xyuas overheating lossis underheating. Overheating lossis underheating ntawm qee qhov chaw ntawm vuam tuaj yeem ua rau muaj qhov tsis xws luag nrog rau cov kab nrib pleb, porosity, lossis txo qis hluav taws xob. Cov cuab yeej ntsuas kub tso cai tuaj hla cov teeb meem no los ntawm txoj hauv kev los ntawm kev muab cov ntawv nyeem ntsuas kub hauv lub sijhawm. Thermocouples tuaj yeem ceev nrooj tuaj hla txhua qhov kev kub ntxhov txawv txav lossis poob thiab ceeb toom rau tus welder lossis tus neeg teb xov tooj. Qhov no tso cai rau kev hloov kho sai sai, nrog rau kev kho qhov vuam tsis zoo lossis tiv thaiv tus yam ntxwv yog tias tsim nyog. Los ntawm kev txheeb xyuas overheating los yog underheating, thawj-chav kawm ntawm vuam yuav ua kom ntseeg tau.
Xyuas kom meej manipulate. Qhov ntsuas kub qhov ntev yog qhov tseem ceeb rau kev tuav cov yam ntxwv hauv kev vuam. Los ntawm kev soj ntsuam qhov ntsuas kub tas li, cov neeg ua haujlwm tuaj yeem ua kom paub txog kev xaiv txog qhov vuam yam. Qhov no suav nrog kev kho cov vuam tsis ua haujlwm feem ntau raws li kev nyeem ntawv kub kom tau txais cov welds khov kho thiab vam khom. Cov cuab yeej ntsuas kub, uas suav nrog cov thermocouples, muab cov txheeb cais xav tau tshwj xeeb rau kev tswj hwm, lub ntsiab kom nce qib rau kev tsim khoom thiab txo qis rov ua haujlwm.
Kev ntsuam xyuas weld first-class. Tom qab cov txheej txheem vuam tiav lawm, qhov ntsuas qhov ntsuas qhov ntsuas kub yuav raug siv los ntsuas qhov thawj-chav ntawm cov vuam. Los ntawm kev kawm cov ntaub ntawv ntsuas kub ntawm qhov vuam, nws tseem muaj peev xwm txiav txim siab tias qhov vuam tau ua tiav zoo thiab yog tias muaj kev tshuaj xyuas tom qab vuam lossis kev kuaj mob xav tau. Thermocouples tuaj yeem muab cov ntaub ntawv muaj txiaj ntsig zoo rau thawj-chav tswj lub hom phiaj, pab kom paub tseeb tias cov vuam ua tau raws li qhov yuav tsum tau ua thiab cov lus qhia tshwj xeeb.
