Vuam rov tsim dua ntawm cov menyuam
Cov txheej txheem rau vuam thiab kho cov kab nrib pleb Qhov no suav nrog kev siv cov ntaub ntawv vuam-resistant vuam, xws li Hardfacing Alloys, mus rau cov menyuam nyob rau saum npoo los tsim kho nws qhov ntev thiab txhim kho durability. Cov txheej txheem txhim kho cov menyuam ua haujlwm, txuas ntxiv lub neej pabcuam, thiab txo cov nqi hloov pauv. Nws yog siv tau tshwj xeeb rau cov ntaub raug mob hnyav, cuam tshuam, lossis cov haujlwm kub siab, ua kom muaj kev ua haujlwm smoother.
Cov khoom kom zoo dua
Vuam thiab kho cov kab nrib pleb hauv cov ntaub yog cov ncauj lus kom ntxaws, kev ua tib zoo npaj, thiab tom qab kev kho mob kom ntseeg tau tias cov menyuam cov qauv kev ncaj ncees thiab kev ua tau zoo.
Cov txheej txheem rau vuam thiab kho cov kab nrib pleb hauv cov chais cuam tshuam, kho cov vuam, kho kom huv si-weld kev tswj hwm, thiab kev tswj hwm nruj. Los ntawm ua raws li cov kauj ruam no, koj tuaj yeem rov qab cov menyuam cov qauv kev ncaj ncees thiab txuas ntxiv nws lub neej pabcuam, kom tau txais txiaj ntsig zoo hauv kev ua yeeb yam hauv kev lag luam.
Cov txheej txheem khoom
Ntawm no yog ib theem ntawm cov kauj ruam-kauj ruam qhia rau cov vuam thiab kho cov txheej txheem:
1. Kev npaj
Kev tshuaj xyuas: Txheeb xyuas qhov chaw nyob, ntev, thiab tob ntawm cov kab nrib pleb uas siv kev tshuaj xyuas pom, zas kev kuaj mob, lossis kev kuaj mob ultrasonic.
Kev ntxuav tu: ntxuav cov menyuam nyob saum npoo kom huv tshem cov av, roj, thiab lwm yam paug. Siv cov kuab tshuaj, txhuam hlau, lossis cov cuab yeej sib tsoo.
Cov cua sov ua ntej: Preheat cov menyuam kom txo qis kev pheej hmoo ntawm kev tawg vim cua sov kev ntxhov siab. Cov preheing kub nyob ntawm cov khoom tab sis feem ntau yog li 100 degree mus rau 300 degree.
2. Nrib Kev Npaj
Sib tsoo: Siv ib qho grinder kom tshem tawm cov khoom tawg. Tsim v-zawj lossis u-zawj ua kom ntseeg tau tias weld zoo v nkag mus.
Drilling nres qhov: tho me me qhov ntawm qhov xaus ntawm qhov tawg kom tiv thaiv nws los ntawm kev tshaj tawm ntxiv thaum lub sij hawm vuam.
3. VUAM Txheej Txheem
Xaiv cov qauv vuam: Xaiv cov qauv vuam tsim nyog raws li cov khoom siv cov khoom thiab tawg loj. Cov hau kev suav nrog cov ntaub thaiv hlau arc vuam (smaw), roj tungsten arc vuam (gtaw), thiab roj av arc vuam (GMAW).
Xaiv cov tub lim cov khoom: Xaiv cov khoom siv muab tub lim uas sib phim lossis tau sib xws nrog cov menyuam cov khoom siv. Xav txog yam zoo li lub zog, hardness, thiab hnav tsis kam.
Vuam qhov tsis zoo: Teeb qhov tseeb vuam tsis muaj, nrog rau tam sim no, voltage, thiab kev mus ncig ua si, kom ntseeg tau tias yog cov weld siab.
Txheej txheej: rau kev sib nraws tob, siv ntau weld kis. Ntxuav txhua txheej nrog cov hlau txhuam ua ntej thov cov khaub ncaws tom ntej no kom tshem tawm slag thiab impurities.
4. Post-Weld Kho
Kev ntxhov siab kev ntxhov siab: Ua kev ntxhov siab-txhawb kev kho thaum tshav kub kub kom txo cov kev ntxhov siab ntawm vuam. Qhov no cuam tshuam nrog cov menyuam yaus mus rau qhov ntsuas kub tshwj xeeb (feem ntau 600 degree rau 650 degree) thiab tom qab ntawd cia nws kom txias maj mam.
Kev Txias Txias: Cia cov menyuam kom txias maj mam mus txog chav sov kom tsis txhob thermal tawg.
TAWG Xov: Grind thiab Polish lub cheeb tsam welded los rov qab cov menyuam qhov ntev thiab qhov ua tiav. Ua kom cov nplaim kom tiv thaiv kom tsis txhob muaj kev ntxhov siab.
5. Tswjhwm Zoo
Kev Ntsuam Xyuas Pom: Tshawb xyuas Weld rau cov kev tsis xws luag xws li cov kab nrib pleb, porosity, thiab undercutting.
Tsis yog-kev sim ua phem (NDT): Siv NDT txoj kev zoo li kev sim tshuaj ntsuab, lossis ntsuas hluav taws xob ua kom paub meej tias lub weld yog pub dawb los ntawm kev tsis taus sab hauv.
Kev Ntsuam Xyuas Sab Nrig: Txheeb xyuas tias cov menyuam qhov ntev thiab geometry yog nyob rau hauv kev tsim kho kom tau.
6. Cov kauj ruam kawg
Cov Txheej Txheem: Thov cov txheej txheem tiv thaiv lossis kev kho mob rau thaj chaw kho kom txhim kho corrosion tsis kam thiab hnav cov khoom.
Reactembly: rekseme cov menyuam mus rau hauv cov tshuab, kom txhua yam cov khoom siv tau raug raws li thiab nyab xeeb.
Kuaj: Kev kuaj cov haujlwm ua haujlwm kom ntseeg tau cov menyuam ua haujlwm kom raug thiab kho tau rov qab nws qhov kev ua tau zoo.
Cim npe nrov: Vuam rov tsim kho cov menyuam, Tuam Tshoj vuam rov tsim kho cov menyuam tuam ntxhab, cov chaw muag khoom, Hoobkas
