Lub luag haujlwm ntawm ntsuas kub ntsuas cov cuab yeej hauv steel qauv vuam yog dab tsi?

Cov cuab yeej ntsuas kub ntsuas ua haujlwm tseem ceeb hauv cov hlau zoo li vuam. Thaum nws koom nrog cov thermocouples, lawv tau txais lub peev xwm tshwj xeeb ntawm cov txheej txheem no.
Saib xyuas preheating kub. Ua ntej welding metallic lug, preheating feem ntau yuav tsum tau kom txuag tau koj cov kab nrib pleb thiab xyuas kom meej weld zoo. Kev ntsuas kub ntsuas, uas suav nrog cov thermocouples, tuaj yeem siv los tso saib qhov ntsuas kub ua ntej. Thermocouples tuaj yeem txuas rau hauv pem teb hlau kom muaj qhov ntsuas kub kom raug. Qhov no ua kom paub tseeb tias qhov kub thiab txias yog nyob rau hauv qhov tshwj xeeb ntau yam rau cov txheej txheem vuam zoo.
Tswj qhov kub ntawm interpass. Thaum lub sij hawm welding, qhov kub thiab txias ntawm weld passes tseem ceeb heev. Qhov kub ntawm qhov sib cuam tshuam ntau dhau tuaj yeem ua rau muaj kev cuam tshuam loj heev thiab muaj peev xwm ua haujlwm tsis zoo. Qhov ntsuas kub ntsuas gadget tuaj yeem siv los tso saib thiab tswj qhov ntsuas kub sib txawv. Thermocouples tuaj yeem nyob ze rau qhov chaw sib txuas kom ntsuas qhov kub thiab txias tom qab txhua qhov dhau mus. Qhov no cia nyob rau hauv welders hloov cov vuam tsis tau kom qhov zoo interpass kub.
Tshawb xyuas tom qab-weld warmness kho kub. Qee qhov xwm txheej, kev kho mob tom qab vuam yog qhov tseem ceeb los txo cov kev ntxhov siab seem thiab txhim kho lub tsev neeg kho tshuab ntawm vuam. Kev ntsuas kub ntsuas gadget yog siv los tso saib qhov ntsuas kub rau lub sijhawm tom qab kev kho cua sov. Thermocouples tuaj yeem txuas nrog cov duab welded kom paub tseeb tias qhov sov sov kho qhov kub thiab txias yog khaws cia rau hauv qhov xav tau ntau yam. Qhov no ua kom yooj yim rau kev ua tiav cov kev hloov kho metallurgical nyiam thiab txhim kho lub zog thiab ruaj khov ntawm cov vuam.
Kev ntsuas weld zoo heev. Kev ntsuas kub tuaj yeem muab cov txheeb cais muaj txiaj ntsig kwv yees li qhov zoo tshaj plaws weld. Cov qauv kub tsis zoo lossis qhov hloov pauv kuj tseem tuaj yeem cuam tshuam txog kev muaj peev xwm ua tsis tiav nrog rau tsis tiav fusion, porosity, lossis tawg. Los ntawm kev taug qab qhov ntsuas kub rau lub sijhawm vuam thiab cov txheej txheem tom qab vuam, engineers thiab cov neeg soj ntsuam tuaj yeem paub txog cov teeb meem muaj peev xwm thiab ua kom raug. Thermocouples tuaj yeem siv los tshawb pom qhov ntsuas kub uas tuaj yeem qhia tau tias muaj qhov tsis xws luag.
Ua kom muaj kev tiv thaiv. Cov kub kub uas tsim los rau lub sijhawm vuam tuaj yeem ua rau muaj kev phom sij. Kub ntsuas gadget yooj yim hauv kev taug qab qhov ntsuas kub kom paub tseeb tias nws nyob hauv qhov txwv tsis pub muaj kev nyab xeeb. Piv txwv li, yog tias qhov kub tau txais siab dhau lawm, nws muaj peev xwm ua rau hluav taws kub los yog ua rau cov khoom nyob ib puag ncig. Thermocouples tuaj yeem siv los tshawb pom qhov kub thiab txias nce thiab ua rau lub tswb lossis kev tiv thaiv.
