Thaum siv aHlau Laser Vuam Tshuabrau vuam stainless hlau, kev xaiv ntawm cov roj thaiv kev tiv thaiv yog ib qho tseem ceeb rau kev ua tiav cov txiaj ntsig zoo -. Lub luag haujlwm tseem ceeb ntawm kev tiv thaiv roj yog los tiv thaiv lub pas dej molten weld los ntawm atmospheric contaminants xws li oxygen thiab nitrogen, uas tuaj yeem ua rau oxidation thiab porosity. Txawm tias muaj ntau yam gases tuaj yeem siv tau, argon thiab nitrogen yog qhov ntau tshaj plaws. Txhua tus muaj qhov sib txawv ntawm qhov zoo ntawm vuam, thiab kev nkag siab qhov sib txawv no yog qhov tseem ceeb rau kev ua kom zoo dua koj cov txheej txheem vuam. Phau ntawv qhia no tshawb txog qhov cuam tshuam ntawm nitrogen thiab argon ntws tus nqi ntawm cov yam ntxwv tseem ceeb, nrog rau kev sib koom ua ke thiab qhov chaw vuam.
ArgonvsNitrogen
Qhov cuam tshuam ntawm Shielding Gas ntawm Weld Joint Strength
Weld kev sib koom ua ke lub zog yog qhov taw qhia tseem ceeb ntawm - zoo weld. Cov yam ntxwv xws li hom roj, ntws tus nqi, lub zog laser, thiab vuam ceev txhua yam cuam tshuam rau tus yam ntxwv no. Cov txheej txheem uas argon thiab nitrogen cuam tshuam lub zog yog qhov sib txawv.
Argon Flow Rate & Weld Strength
Argon yog ib qho roj inert, txhais tau tias nws tsis muaj tshuaj lom nrog cov hlau. Nws lub luag haujlwm tseem ceeb yog tshem tawm huab cua ncig lub pas dej ua ke, tiv thaiv oxidation. Kev tswj xyuas kom zoo argon ntws tus nqi ua kom muaj kev tiv thaiv ruaj khov, uas pab tiv thaiv qhov tsis xws luag xws li porosity thiab tsis sib xws. Txawm li cas los xij, argon ntau dhau tuaj yeem tsim cov pa roj ntau dhau, ua rau lub pas dej sib txuas tsis ruaj khov thiab qhov tsis xws luag uas cuam tshuam lub zog. Hloov pauv, qhov tsis txaus txaus ua rau lub pas dej sib txuas ua rau muaj kev cuam tshuam ntawm atmospheric, kuj txo lub zog.
Cov porosity thiab oxidation tsuas yog ob qho ntawm cov faults welders ntsib nyob rau hauv txhua hnub ntau lawm - rau ib tug systematic walkthrough, saibntau laser vuam faults thiab lawv cov kev daws teeb meem.
Nitrogen Flow Rate & Weld Strength
Nitrogen cov nyhuv yog qhov nyuaj dua thiab muaj txiaj ntsig zoo rau qee qhov kev siv. Nws ua raws li cov roj tiv thaiv tab sis kuj ua rau cov ntsiab lus alloying nyob rau hauv stainless hlau, tshwj xeeb tshaj yog chromium thiab npib tsib xee, tsim nitrides. Cov nitrides no txhawb nqa lub zog tensile, hardness, thiab qaug zog tsis kam ntawm weld joint. Rau kev thov cov ntawv thov uas xav tau siab - lub zog welds, zoo li cov ua los ntawm aSiab -Speed online Tube Laser Vuam Tshuab, qhov nruab nrab nitrogen ntws tuaj yeem txhim kho cov cuab yeej cuab tam ntawm cov vuam.
Qhov cuam tshuam ntawm Shielding Gas ntawm Weld Area
Weld cheeb tsam, los yog weld hlaws dav, yog lwm yam tseem ceeb hauv weld zoo. Qhov loj dua, ntau qhov sib xws ntawm qhov sib txuas qhia tau zoo dua fusion thiab tag nrho kev sib koom ua ke. Qhov kev xaiv ntawm shielding roj thiab nws tus nqi ntws ncaj qha cuam tshuam rau lub pas dej molten lub thermal stability thiab fluidity, uas nyob rau hauv lem cuam tshuam rau lub weld cheeb tsam.
Argon Flow Rate & Weld Area
Argon qhov cuam tshuam rau thaj tsam weld feem ntau yog thermal. Ib qho kev tswj xyuas tus nqi pab tswj qhov kub ntawm lub pas dej molten ruaj khov, txhawb kev ua kom zoo sib xws thiab cov hlaws dav dav. argon ntau dhau tuaj yeem cuam tshuam lub pas dej molten nrog turbulent airflow, ua rau qhov kub thiab txias tsis sib xws thiab thaj chaw weld tsis sib xws. Qhov tsis txaus txaus txaus tuaj yeem ua rau lub pas dej molten kom txias ua ntej, ua rau thaj tsam me me.
Nitrogen Flow Rate & Weld Area
Nitrogen tuaj yeem txhim kho cov thermal stability thiab fluidity ntawm lub pas dej molten, uas yuav pab tsim kom muaj qhov dav dua, zoo dua qhov chaw weld. Nws cov tshuaj lom neeg cov tshuaj tiv thaiv nrog cov hlau kuj tuaj yeem txhawb nqa kev faib tawm ntawm cov hlau alloying, ntxiv kev txhim kho qhov zoo thiab sib xws ntawm cov vuam. Txawm li cas los xij, nitrogen ntau dhau tuaj yeem ua rau muaj nitriding ntau dhau, uas tuaj yeem ua rau lub pas dej molten stiffen thiab txwv nws txoj kev nthuav dav, yog li txwv qhov chaw weld.
Hauv cov ntsiab lus, xaiv qhov raug shielding roj thiab tswj tus nqi txaus txaus yog qhov tseem ceeb rau kev ua kom zoo dua koj cov txheej txheem vuam. Rau lub Hlau Laser Vuam Tshuab los yog siab -Speed online Tube Laser Vuam Tshuab, siv argon muab ib qho chaw ruaj khov, inert ib puag ncig uas tiv thaiv oxidation, thaum siv nitrogen tuaj yeem txhim kho cov khoom siv ntawm cov vuam sib txuas, ua kom muaj zog thiab ruaj khov. Qhov kev xaiv zoo tshaj plaws nyob ntawm koj daim ntawv thov tshwj xeeb thiab cov yam ntxwv weld xav tau.
