Lub hauv paus tseem ceeb ntawm kev ua kom cov vuam zoo ntawm cov khoom siv hluav taws xob hloov pauv yog nyob rau hauv kev xaiv siab - cov txheej txheem vuam zoo, ua kom cov vuam tsis zoo, siv cov thev naus laus zis kev sim siab, thiab nruj me ntsis siv cov txheej txheem kev khiav hauj lwm nruj me ntsis los tswj qhov tsis xws ntawm qhov chaw thiab xyuas kom cov vuam nruj thiab cov qauv kev ntseeg tau.
Xaiv High-Cov txheej txheem vuam zoo
Gas-shielded vuam (MIG/MAG/CO₂ vuam): dav siv nyob rau hauv corrugated tso tsheb hlau luam thiab loj structural Cheebtsam, nws muaj qhov zoo ntawm ruaj khov arc, sib sib zog nqus nqus, thiab tsawg spatter, zoo tiv thaiv weld oxidation thiab txhim kho nruj.
Submerged arc vuam: Haum rau ntev, ncaj welds, nws muaj kev vuam zoo, cov khoom siv hluav taws xob zoo, thiab tsim kom zoo nkauj zoo nkauj, tsim rau kev tsim cov khoom loj ntawm cov welds loj hauv lub cev tank.
Laser welding thiab electron beam vuam: Cov no yog siab - lub zog nqaj vuam thev naus laus zis nrog cov cua sov me me- thaj chaw cuam tshuam, qhov deformation tsawg, thiab qhov loj weld qhov tob- rau - dav piv, haum rau siab - cov qauv sealing zoo, sawv cev rau cov kev taw qhia yav tom ntej.
Automated Welding System: Kev sib txuas cov neeg hlau thiab laser vuam seam nrhiav tshuab, qhov system no ua tiav "qhia-dawb" kev hloov pauv tsis siv neeg hloov kho, kom ntseeg tau qhov sib txawv ntawm cov vuam sib txuas thiab txhim kho qhov sib xws ntawm vuam thiab kis tus nqi.
Optimizing Vuam Parameters
Tam sim no thiab Voltage Matching: Ntau dhau tam sim no tuaj yeem ua rau hlawv -los ntawm lossis qis dua, thaum tsis txaus tam sim no tuaj yeem ua rau nkag mus tsis tiav. Voltage cuam tshuam rau arc stability thiab yuav tsum tau kho kom zoo raws li phaj thickness thiab vuam hlau txoj kab uas hla.
Welding Speed Control: Kev ceev ntau dhau tuaj yeem ua rau tsis tiav fusion thiab porosity; Kev ceev ntau dhau ua rau cov cua kub nkag, ua rau deformation thiab grain coarsening. Qhov ntau yam tsim nyog yuav tsum tau teeb tsa raws li cov khoom siv.
Preheating thiab Post-Kev kho cua sov: Preheating tuab daim hlau los yog siab-lub zog steel (150-200 degree) txo qhov kev ntxhov siab. Tom qab-weld stress-relief annealing tshem tawm qhov seem welding kev nyuaj siab thiab tiv thaiv kev tawg tawg vim kev co thaum ua haujlwm.
Groove Design and Assembly Accuracy: Xyuas kom meej tias qhov zawj lub kaum sab xis thiab qhov sib txawv raws li cov txheej txheem yuav tsum zam kom tsis txhob muaj kev nkag mus tsis tiav lossis cov hlaws hlaws uas tshwm sim los ntawm kev sib dhos sib txawv.
Advanced Test Technologies
Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):
X-ray Inspection: Siv los txheeb xyuas qhov tsis xws luag xws li porosity, slag inclusions, thiab tawg hauv welds;
Kev Ntsuas Ultrasonic: Tsim nyog rau kev kuaj xyuas qhov sib sib zog nqus tawg thiab tsis tiav kev nkag mus, nrog rau siab rhiab heev, haum rau cov phaj tuab tuab.
Air Tightness thiab Pressure Test:
Kev Ntsuas Siab Zoo: Sau nrog 35-50 kPa ntawm huab cua qhuav thiab tuav lub siab ntev li 24 teev. Lub siab poob qis tshaj tus nqi teev qhia tias 合格 (tsim nyog);
Kev Ntsuas Siab Tsis Zoo: Tshem tawm mus rau qis dua 133 Pa thiab saib xyuas lub siab rov qab los xyuas qhov kev sib khi tag nrho.
Kerosene Penetration Test: Siv cov roj av rau ntawm ib sab ntawm qhov vuam thiab saib xyuas qhov pom ntawm sab nraud. Siv rau kev tshuaj ntsuam sai sai ntawm cov dej xau.
Kev Tshawb Fawb Online Laser: Kev sib koom ua ke laser sensors rau hauv cov kab ntau lawm los saib xyuas cov txheej txheem vuam zoo hauv lub sijhawm thiab ua tiav kaw - voj kev tawm tswv yim tswj.
