Hnyav-cov haujlwm welded steel puag thav duab yog lub hauv paus tsim rau cov cuab yeej siv, tshuab, thiab loj- cov phiaj xwm loj. Lub qhov dej zoo-tsim lub hauv paus ncej faib cov khoom thauj tau zoo, muab kev txhawb nqa nruj raws li cov xwm txheej tsis muaj zog, thiab tswj xyuas qhov kev ruaj ntseg thoob plaws hauv nws lub neej kev pabcuam. Cov lus qhia no tshuaj xyuas cov qauv tsim, cov qauv tsim, thiab kev tsim vaj tsev zoo ntawm welded steel puag thav duab- muab B2B cov neeg yuav khoom thiab cov kws ua haujlwm ua haujlwm nrog kev paub los ntsuas cov khoom tsim tau zoo thiab qhia cov kev daws teeb meem rau lawv cov ntawv thov.
Core Cheebtsam ntawm Welded Steel Base Ncej
Welded Joints
Lub welded sib koom ua ke yog qhov chaw sib cuag uas ob lossis ntau qhov chaw ua haujlwm tau txuas mus tas li thaum lub sijhawm vuam. Rau hnyav- lub luag haujlwm hauv paus ncej, feem ntau cov kev sib koom ua ke muaj xws li:
Cov pob qij txha:Siv rau kev sib txuas daim hlau uas zoo sib xws hauv tib lub dav hlau. Tag nrho - nkag mus hauv pob tw welds muab lub zog siab tshaj plaws rau cov tswv cuab tseem ceeb.
T- sib koom ua ke:Hom kev sib koom ua ke ntau tshaj plaws hauv lub thawv- ntu ntu, txuas cov tswv cuab ntsug mus rau kab rov tav puag daim hlau. Fillet welds ntawm ob sab muab lub zog txaus rau feem ntau ntawm kev thauj khoom.
Cov pob qij txha:Siv rau ntawm cov ces kaum uas ob tug tswv cuab sib ntsib ntawm 90℃. Kev npaj kom raug (beveling) ua kom cov hauv paus nkag mus tag nrho.
Xaiv qhov kev sib koom ua ke tsim nyog yog qhov tseem ceeb rau kev ua kom lub cev muaj zog thiab xau- nruj. Peb pab neeg ua haujlwm engineering siv finite element tsom xam (FEA) los txheeb xyuas cov peev txheej sib koom ua ke raws li qhov xav tau ntawm kev thauj khoom.
Welds
Lub vuam nws tus kheej- cov hlau molten solidified ua kev sib txuas- ncaj qha txiav txim siab kev sib koom ua ke. Ntawm Tianhua Yihe, peb cov tshuab vuam neeg hlau tswj cov khoom siv hluav taws xob (feem ntau yog 1.5–3.5 kJ / mm rau cov qauv vuam), kev mus los nrawm, thiab xaim pub tus nqi kom tsim tau zoo ib yam, tsis xws luag- welds dawb. Txhua qhov tseem ceeb welds raug kuaj pom, thiab NDT (ultrasonic lossis magnetic particle) kuaj raws li ISO 17640 cov cai.
Fusion Zone thiab Heat -Affected Zone (HAZ)
Ob thaj chaw metallurgical tsim nyog tau txais kev saib xyuas hauv hnyav -cov haujlwm welded thav duab:
Fusion Zone:Qhov kev hloov pauv ntawm thaj chaw ntawm cov khoom siv vuam hlau thiab cov hlau tsis muaj kev cuam tshuam. Ntawm no, tshuaj muaj pes tsawg leeg thiab microstructure hloov pauv loj. Tswj cov vuam tsis sib xws (tam sim no, voltage, ceev) tswj cov fusion cheeb tsam dav thiab cov khoom.
Thaum tshav kub kub-Affected Zone (HAZ):Lub hauv paus hlau cheeb tsam uas, thaum tsis melted, muaj kev thermal cuam tshuam hloov nws cov microstructure thiab mechanical zog. Rau Q345 steel welded nrog nruab nrab cua sov input, HAZ feem ntau txuas 2-5 hli los ntawm cov ntiv taw vuam. Kev nkag siab txog tus cwj pwm HAZ yog qhov tseem ceeb hauv kev kwv yees lub neej qaug zog thiab ua rau lub cev tawg.
Cov Ntsiab Cai Tsim rau Hnyav -Lub Luag Haujlwm Base Frames
Load Distribution thiab Stiffener Placement
Lub hauv paus tsim qauv tsim kom ntseeg tau tias cov khoom siv thauj khoom hloov tau zoo rau lub hauv paus. Cov qauv tsim tseem ceeb muaj xws li:
Base phaj:Feem ntau 20mm-50mm tuab, qhov loj me los faib cov khoom hnyav thiab muab ntsia liaj qhov rooj -cov ntsiab lus txuas. Lub hauv paus phaj flatness yuav tsum tsis pub dhau 0.5 hli / m² kom ntseeg tau tias cov kabmob sib xws.
Gusset phaj:Daim duab peb sab stiffeners welded ntawm kev sib tshuam sib koom ua kom muaj zog hauv zos thiab tiv thaiv lub sijhawm khoov. Gusset thickness feem ntau yog 60-80% ntawm cov tswv cuab lub ntsiab thickness.
Internal diaphragms:Transverse daim hlau welded nyob rau hauv lub thawv seem kom tiv thaiv lub zos buckling nyob rau hauv compressive loads. Diaphragm spacing feem ntau yog 1-1.5 npaug ntawm seem qhov tob.
Welding Sequence thiab Distortion Control
Vuam induces thermal expansion thiab contraction, ua rau distortion yog tias tsis tswj kom zoo. Peb cov txheej txheem fabrication muaj xws li:
Ua ntej- teeb tsa kev cuam tshuam kev cuam tshuam (ua ntej- cov tswv cuab khoov los ntawm 1–3mm nyob rau sab nraud ntawm qhov kev xav tsis sib haum)
Balanced welding sequence (alternating sab kom sib npaug shrinkage rog)
Kev ntxhov siab thaum xav tau (post-weld kho cua sov ntawm 550-650℃rau tuab-section welds)
Qhov kawg machining ntawm qhov chaw tseem ceeb tom qab vuam kom ua tiav qhov kev ua siab ntev
Qhov zoo ntawm Welded Fabrication rau Loj -Scale Steel Frames
Piv rau bolted kev sib txuas thiab cam khwb cia lwm txoj kev, welded steel puag ncej muaj qhov zoo sib xws:
Structural rigidity:Welded pob qij txha tsim kev sib txuas monolithic uas tiv thaiv kev thauj khoom thiab kev vibration - tseem ceeb rau cov khoom siv hauv paus raug rau kev ua haujlwm quab yuam.
Luj efficiency:Welded kev tsim kho tshem tawm qhov xav tau ntawm cov hlau txuas hnyav thiab cov ntsia hlau arrays, txo qhov hnyav tag nrho los ntawm 15-25% piv rau qhov sib npaug bolted tsim.
Tsim yooj yooj yim:Welded fabrication haum rau cov geometries nyuaj, tsis yog -tus qauv ntoo khaub lig- ntu, thiab qhov chaw- cov kev hloov kho tshwj xeeb uas tawm -- ntu txee ua tsis tau.
Kev sib txuas kaw:Nruam welds tsim weathertight, corrosion-cov pob qij txha tiv taus-tshwj xeeb yog qhov tseem ceeb rau cov khoom siv sab nraum zoov hauv ib puag ncig Australian corrosive.
Tus nqi -effectiveness:Rau nruab nrab mus rau loj ntau lawm khiav, welded fabrication yog ntau yig dua casting (tsis muaj qauv / cuab yeej nqi) thiab sai dua complex bolted los ua ke.
