Nov yog qee txoj hauv kev los xyuas kom meej qhov vuam zoo ntawm DH32 shipbuilding steel phaj:
I. Kev npaj ua ntej vuam
Kev tshuaj xyuas cov khoom:
Ua kev soj ntsuam nruj ntawm DH32 steel phaj kom ntseeg tau tias tsis muaj kab nrib pleb, delamination, xeb thiab lwm yam tsis xws luag ntawm cov phaj hlau. Txhua qhov tsis xws luag tuaj yeem ua rau vuam tsis xws luag thaum lub sijhawm vuam thiab cuam tshuam rau vuam zoo.
Txheeb xyuas qhov zoo ntawm cov khoom siv vuam (electrodes, vuam hlau, vuam fluxes, thiab lwm yam) kom ntseeg tau tias lawv ua tau raws li cov txheej txheem vuam uas yuav tsum tau ua thiab nyob rau lub sijhawm siv tau. Cov khoom siv vuam sib txawv yog tsim rau kev sib txawv vuam thiab steel phaj thicknesses. Xaiv cov khoom siv vuam tsim nyog yog lub hauv paus rau kev ua kom cov vuam zoo.
Groove npaj:
Raws li cov txheej txheem vuam yuav tsum tau, npaj qhov tsim nyog groove duab thiab loj. Kev npaj ntawm qhov zawj yuav tsum xyuas kom meej tias cov hauv paus hniav ntawm cov welded sib koom ua ke tuaj yeem ua tiav tag nrho, thiab tib lub sijhawm kom tsis txhob muaj qhov tsis xws luag xws li kev nkag mus tsis tiav thiab slag suav nrog.

Chemical Composition thiab Mechanical Property:

 

 

 

Rau cov phaj tuab welding, ntau txheej thiab multi-pass vuam yuav tsum tau. Lub sijhawm no, lub kaum sab xis thiab qhov tob ntawm qhov zawj yuav tsum tsim nyog raws li tus naj npawb ntawm cov txheej txheem vuam thiab cov txheej txheem vuam.
Qhov saum npoo ntawm qhov zawj yuav tsum tau ntxuav kom tshem tawm cov impurities xws li roj stains, xeb, thiab noo noo kom ntseeg tau tias vuam zoo. Cov txheej txheem tu tshuab (xws li sandblasting, sib tsoo, thiab lwm yam) tuaj yeem siv los ua cov tshuaj ntxuav tes (xws li pickling, thiab lwm yam) tuaj yeem siv.
Preheating kev kho mob:
DH32 steel phaj yuav tsum tau preheated ua ntej welding kom txo cov vuam seem seem thiab tiv thaiv qhov tshwm sim ntawm vuam tawg. Lub preheating kub yuav tsum tau txiav txim raws li tej yam xws li thickness, tshuaj muaj pes tsawg leeg, thiab vuam txoj kev ntawm cov hlau phaj.
Preheating tuaj yeem ua tau los ntawm txoj kev xws li nplaim hluav taws xob thiab hluav taws xob cua sov. Lub preheating ntau yam yuav tsum muaj xws li ib tug tej yam dav cheeb tsam ntawm ob sab ntawm weld. Thaum lub sij hawm preheating txheej txheem, lub uniformity ntawm lub preheating kub yuav tsum nruj me ntsis tswj kom tsis txhob muaj overheating hauv zos los yog underheating.
