Weldability zoo: Lub phaj muaj qhov zoo tshaj plaws weldability, tso cai rau kev ua haujlwm zoo thiab kev tsim cov nkoj. Cov kws tshaj lij tuaj yeem siv ntau yam kev siv vuam los koom nrog cov phiaj, ua kom cov pob qij txha muaj zog thiab txhim khu kev qha. Qhov no yog ib qho tseem ceeb heev rau kev ncaj ncees ntawm lub nkoj.

Corrosion Resistance: Muab hais tias cov nkoj ua haujlwm nyob rau hauv marine ib puag ncig, corrosion kuj yog qhov tseem ceeb. Lub Nkoj Lub Tsev Phaj ABS GL LR DNV PLATE EH40 yog kho kom tiv thaiv corrosion, ua kom lub neej ntev ntawm lub nkoj thiab txo cov nqi kho.

Impact Resistance: Nws muaj kev cuam tshuam zoo, tiv thaiv lub nkoj los ntawm kev puas tsuaj los ntawm kev sib tsoo lossis lwm yam cuam tshuam. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov nkoj ua haujlwm hauv txoj kab kev thauj khoom tsis khoom lossis raug huab cua hnyav.

Thermal stability: Cov khoom siv tuaj yeem tswj hwm nws cov khoom siv hluav taws xob ntawm qhov sib txawv ntawm qhov kub thiab txias, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm lub nkoj hauv ntau yam kev ua haujlwm.

 

Daim ntawv thov

 

Nkoj Hull Kev Tsim Kho: Dav siv nyob rau hauv kev tsim kho ntawm lub nkoj hulls, nrog rau lub ntsiab lub cev qauv, decks, thiab bulkheads. Lub zog siab thiab ua haujlwm ntev ntawm lub phaj no ua rau nws tsim nyog rau kev tiv thaiv lub zog thiab kev ntxhov siab los ntawm cov nkoj hauv hiav txwv.

Offshore Structures: Kuj tseem siv tau rau hauv kev tsim kho ntawm ntug dej hiav txwv platform thiab lwm cov qauv hauv hiav txwv uas xav tau cov ntaub ntawv muaj zog thiab corrosion-resistant.

Ship Repair and Maintenance: Nws tuaj yeem siv rau kev kho nkoj thiab kho cov haujlwm, muab kev txhim khu kev qha thiab ruaj khov rau cov khoom puas lossis puas lawm.

Kev cuam tshuam ntawm qhov loj ntawm qhov vuam kub-tshwj xeeb cheeb tsam ntawm shipbuilding high-strength steel ntawm kev ua tau zoo ntawm cov hlau tuaj yeem txhim kho los ntawm cov hauv qab no:

 

I. Optimize vuam txheej txheem
Xaiv txoj kev vuam tsim nyog:
Cov txheej txheem vuam sib txawv muaj qhov sib txawv ntawm qhov loj ntawm thaj tsam kub-tshuaj lom. Piv txwv li, siv cov kev siv hluav taws xob qis qis xws li hlau inert gas welding (MIG) los yog tungsten inert gas welding (TIG) hauv cov roj shielded welding tuaj yeem txo cov cua sov tawm thiab yog li txo qhov loj ntawm cov cua sov hauv cheeb tsam.
Piv nrog rau cov kev siv ib txwm siv arc vuam, cov txheej txheem vuam no tuaj yeem tswj cov vuam tsis zoo dua, txo cov cua sov tawm thaum vuam, thiab txo qhov cuam tshuam thermal ntawm cov hlau.
Tswj welding parameter:
Tsim nyog kho qhov tsis xws li vuam tam sim no, qhov hluav taws xob, thiab vuam ceev tuaj yeem tswj tau cov cua sov tawm. Txo cov vuam tam sim no thiab qhov hluav taws xob thaum tsim nyog nce vuam ceev tuaj yeem txo cov cua sov tsim thaum lub sij hawm vuam thiab yog li txo qhov luaj li cas ntawm cov cua sov cheeb tsam.
Piv txwv li, los ntawm kev sim thiab simulations, txiav txim siab qhov zoo tshaj plaws ntawm kev sib txuas ntawm cov vuam tsis zoo kom txo tau qhov kub ntawm qhov cuam tshuam thaum ua kom cov vuam zoo.
Siv multi-layer thiab multi-pass vuam:
Multi-layer thiab multi-pass welding tuaj yeem cuam tshuam cov vuam cua sov rau hauv ntau qhov kev sib txuas, txo cov cua sov tawm ntawm txhua qhov vuam dhau thiab yog li txo qhov loj ntawm qhov kub ntawm qhov chaw. Lub sijhawm luv luv ntawm txhua qhov kev sib txuas kuj tseem pab kom txias cov hlau thiab txo cov cua sov.
Tsis tas li ntawd, ntau txheej thiab ntau qhov kev sib txuas kuj tuaj yeem txhim kho qhov zoo ntawm welds thiab ua kom lub zog thiab tawv ntawm cov pob qij txha.

 

II. Preheat ua ntej vuam thiab tom qab vuam kev kho cua sov
Preheat ua ntej welding:
Preheating cov hlau ua ntej welding tuaj yeem txo qhov cua txias thaum lub sij hawm vuam, txo qhov hardening nyiam ntawm tshav kub-cuam tshuam cheeb tsam, thiab yog li txhim kho cov vuam kev ua tau zoo ntawm cov hlau. Kev xaiv ntawm preheating kub yuav tsum tau txiav txim raws li tej yam xws li cov khoom, thickness, thiab vuam txoj kev ntawm cov hlau.
Piv txwv li, rau cov hlau muaj zog, qhov kub ntawm qhov preheating feem ntau yog nruab nrab ntawm 100 - 200 degree . Preheating yuav ua tau los ntawm txoj kev xws li nplaim hluav taws kub, hluav taws xob cua sov, los yog induction cua sov.
Kev kho cua sov tom qab vuam:
Kev kho cua sov tom qab vuam tuaj yeem tshem tawm cov kev ntxhov siab uas nyob hauv vuam thiab txhim kho cov qauv thiab kev ua haujlwm ntawm thaj chaw muaj kev kub ntxhov. Cov kev kho cua sov tom qab vuam feem ntau muaj xws li annealing, normalizing, thiab tempering.
Piv txwv li, rau cov qauv welded tseem ceeb, kev kho tempering tuaj yeem siv. Lub welded sib koom yog rhuab mus rau ib tug tej yam kub thiab tuav rau ib lub sij hawm ntawm lub sij hawm, thiab ces txias maj mam. Qhov no tuaj yeem txo qhov hardness ntawm thaj chaw tshav kub, ua kom tawv nqaij, thiab txo qhov tshwm sim ntawm cov kab nrib pleb.
