Qhov txawv ntawm qhov kub thiab txias npaum li cas rau lub sijhawm txias ntawm lub tshuab hluav taws xob fusion vuam tshuab?

1. Ambient kub them nyiaj muaj nuj nqi: welding zog them ntawm hluav taws xob fusion vuam tshuab yog tsuas yog cov nyiaj them rau ambient kub. Tus qauv qhia txog qhov yuav tsum tau ua rau qhov ntsuas qhov ntsuas kub ntawm qhov raug thiab xav kom tus welder muab cov ntaub ntawv qhia txog qhov ntsuas kub ntawm qhov ntsuas kub. Qhov no txhais tau hais tias tus welder yuav tsum tau kho cov vuam tsis raws li qhov kev hloov ntawm ambient kub los xyuas kom meej qhov vuam zoo.
2. Kev cuam tshuam ntawm kev ntsuas qhov ntsuas kub: Txawm hais tias feem ntau cov tshuab hluav taws xob fusion vuam tau nruab nrog cov cuab yeej ntsuas ntawm tus maub los, nws yog qhov pom tseeb tias qhov ntsuas kub tau pom tseeb cuam tshuam los ntawm cov cua sov ntawm lub fuselage. Qhov laj thawj tseem ceeb yog tias cov cuab yeej ntsuas tau ncaj qha rau ntawm tus maub los. Nws tau pom nyob rau hauv qhov kev ntsuam xyuas uas muaj ntau tus welders tau yooj yim tshaj li qhov tso cai ntau teev nyob rau hauv tus qauv (qhov kev sib txawv ntawm qhov tso cai tsis pub tshaj ± 1 degree) tom qab ua haujlwm ntau tshaj li ib nrab teev. Qhov no qhia tau hais tias qhov kev hloov ntawm ambient kub yuav cuam tshuam ncaj qha rau qhov tseeb ntawm cov cuab yeej ntsuas, thiab tom qab ntawd cuam tshuam rau qhov chaw ntawm vuam tsis.
3. Qhov sib txawv ntawm cov txheej txheem them nyiaj: muaj qhov sib txawv ntawm cov txheej txheem them nyiaj los ntawm cov welder sib txawv. Txij li cov txheej txheem tsis ua cov kev cai tshwj xeeb rau qhov ntsuas kub ntawm qhov ntsuas kub, thaum siv hom kev tuav, qee cov welders tau teeb tsa nrog cov nyiaj them poob haujlwm tab sis lawv txawv, thiab qee qhov tsis teeb tsa nrog cov nyiaj them poob haujlwm. Yog li ntawd, nyob rau hauv cov ntaub ntawv no, seb lub tshuab hluav taws xob fusion vuam yuav tsum muaj kev ua haujlwm ntawm ambient kub them thiab yuav ua li cas coj mus rau qhov kev them nyiaj ntawm cov yeeb nkab fittings tseem xav tau kev sib tham ntxiv.
4. Kev them nyiaj rau hauv hom tsis siv neeg: Thaum siv hom tsis siv neeg, uas yog, luam theej duab thiab nyeem cov barcode ntawm cov yeeb nkab haum, lub tshuab hluav taws xob fusion vuam tuaj yeem nce thiab txo lub sij hawm vuam raws li qhov kev cai barcode raws li qhov ntsuas kub hloov. . Txawm li cas los xij, muaj qhov sib txawv ntawm qhov nyiaj them rau qhov ntsuas kub ntawm lub tshuab hluav taws xob fusion vuam. Feem ntau cov tshuab vuam yog teem rau 20 degree, thiab ib feem me me yog teem rau 23 degree. Qhov no qhia tau hais tias kev hloov pauv ntawm qhov kub thiab txias yuav cuam tshuam ncaj qha rau kev hloov kho ntawm vuam tsis siv neeg hauv hom tsis siv neeg.
5. Vuam efficiency thiab zoo: Thaum ua cov polyethylene hluav taws xob fusion vuam nyob rau hauv qhov chaw txias, cov hluav taws xob cua sov hlau feem ntau yog siv rau lub hwj chim ncaj qha preheating, tab sis txoj kev no tseem cuam tshuam rau ib puag ncig thiab muaj kev tswj tsis zoo ntawm lub zos kub. Los ntawm preheating cua nrog ib tug ntse vuam tshuab nrog vuam ambient kub tswj, lub zos qhov kub thiab txias yuav tswj tau zoo, cov kev cuam tshuam ib puag ncig yuav tiv thaiv tau, thiab vuam efficiency tuaj yeem txhim kho.
6. Kev cuam tshuam thaum lub caij txias: Feem ntau tom qab cua sov ntawm hluav taws xob fusion vuam ua tiav, cov yeeb nkab tau txias los ntawm kev sib pauv cua sov nrog rau qhov chaw sab nraud. Kev ua kom txias sai sai los ntawm txoj kev ua kom txias no tuaj yeem ua rau qhov chaw vuam yuav txo qis sai, ua rau muaj kev ntxhov siab thermal lossis tsis muaj roj khiav tawm, ua rau tawg, deformation, thiab qhov hws hauv qhov chaw vuam. Kev txawj ntse vuam tshuab nrog vuam ib puag ncig qhov kub thiab txias tswj tuaj yeem tswj qhov kub ntawm ib puag ncig hauv cheeb tsam kom maj mam poob, yog li txo cov thermal kev nyuab siab, txo deformation, txhim kho vuam zoo, tsis txhob npuas thiab tawg, thiab yog li txhim kho vuam zoo.
