Vuam tsis thiab cov txheej txheem rau API 5L X46 cov kav dej yuav tsum tau ua tib zoo tswj kom muaj kev ncaj ncees thiab kev ua haujlwm ntawm cov pob qij txha.
Welding parameters thiab cov txheej txheem
Welding parameters: Xaiv qhov tsim nyog vuam tam sim no, qhov hluav taws xob, kev mus los ceev, thiab kev tiv thaiv cov roj muaj pes tsawg leeg yog qhov tseem ceeb rau kev ua tiav qhov xav tau weld nkag mus, weld hlaws zoo li, thiab cov khoom siv kho tshuab.
Vuam thev naus laus zis: Cov txheej txheem vuam xws li kev sib txuas ntau dhau, kev tswj qhov kub thiab txias, thiab cov kab hauv qab kev ua kom zoo tuaj yeem pab txo qhov tsim ntawm qhov tsis xws luag xws li porosity, tsis muaj fusion, thiab deformation.
Kev kho cua sov tom qab vuam (PWHT): API 5L X46 kav dej feem ntau xav tau PWHT txhawm rau txo qis kev ntxhov siab, txhim kho microstructural zog, thiab ua kom tag nrho cov vuam lub zog thiab tawv.
Kev tshuaj xyuas zoo tom qab vuam
Kev tshuaj xyuas qhov tshwm sim: Tshawb xyuas qhov kev nkag mus ntawm vuam thiab qhov zoo ntawm cov fusion seam kom ntseeg tau tias vuam zoo.
Kev soj ntsuam lub suab: Siv lub cuab yeej los coj mus rhaub cov vuam los mloog lub suab thiab txiav txim qhov loj thiab qhov zoo ntawm lub pas dej weld.
Kev tshuaj xyuas qhov ceev tam sim no: Siv cov cuab yeej tshwj xeeb los kuaj xyuas qhov ceev tam sim no los xyuas kom meej qhov zoo ntawm cov kav dej tom qab vuam.
Weld seam kev kho mob: tshem tawm vuam slag thiab oxides, kos cov cim vuam, thiab xyuas kom tag nrho cov vuam.
Cov lus qhia ua haujlwm tshwj xeeb
Kev kho cov yeeb nkab phab ntsa tuab: Thaum cov yeeb nkab phab ntsa thickness ntau dua 5 hli, qhov kawg ntawm cov yeeb nkab yuav tsum tau beveled thiab cov oxide txheej ntawm lub bevel yuav tsum tau muab tshem tawm.
Kev kho cov pas nrig vuam: txheej txheej ntawm vuam pas nrig yuav tsum tsis txhob poob los yog muaj cov kab nrib pleb, thiab nws yuav tsum tau qhuav ntawm 350 ~ 400 degree.
