Titanium Welding Rod AWS 5.16

Titanium vuam rods yog siv nyob rau hauv vuam daim ntawv thov qhov twg titanium yuav tsum tau rau nws superior zog, tsawg ntom, thiab corrosion kuj. Nws yog feem ntau siv nrog cov txheej txheem roj tungsten arc vuam (GTAW), tseem hu ua Tungsten Inert Gas (TIG) vuam. Nws yog qhov tshwj xeeb tsim los ntawm American Welding Society (AWS) rau kev siv titanium vuam. AWS 5.16 specification npog cov kev cai rau kev faib cov khoom titanium vuam electrodes thiab rods siv rau cov roj tungsten arc vuam (GTAW) thiab plasma arc vuam (PAW) txheej txheem.

Specification:

Feem ntau titanium alloys:

Cov nram qab no yog cov titanium alloys. Muaj ntau yam yuav tsum tau xav txog thaum xaiv ib lub hauv paus titanium hlau los yog titanium weld muab tub lim hlau kom tau raws li kev txhim kho corrosion lossis cov khoom siv kho tshuab, thiab yog tias koj xav tau cov ntaub ntawv no, koj tuaj yeem tiv tauj peb cov kws tshaj lij rau kev tawm tswv yim.

Rau Titanium electrode cov ntaub ntawv kos nrog peb ncaj qha. Cov ntaub ntawv ntim khoom siv rau Vuam-titanium alloys tau piav qhia hauv AWS 5.16 - Specification rau Titanium thiab Titanium Alloy Weld Electrodes thiab Rods.

Qhov siab tshaj plaws kub ntau yam rau titanium structural applications yog 800 txog 1100⁰F (427-593^oC), nyob ntawm qhov xaiv alloy thiab nws cov xwm txheej. Titanium yog siv rau cov ntawv thov cryogenic vim nws tsis muaj qhov txaus ntshai ntawm qhov kub thiab txias hloov pauv. Unalloyed titanium feem ntau xaiv rau nws zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas siab zog tsis xav tau. Ntxiv rau qhov tsis muaj khoom lossis kev lag luam titanium, cov chav sib txawv ntawm titanium alloys tau piav qhia los ntawm metallurgical hom hu ua alpha, alpha-beta, thiab beta, uas sawv cev rau cov theem tseem ceeb tam sim no hauv microstructure.

Titanium vuam hlau tsum:

Nrhiav titanium vuam hlau lwm tus neeg thiab cov ntaub ntawv zoo titanium. Kev siv cov hlau ua kom zoo heev yog qhov tseem ceeb rau kev tsim cov titanium welds zoo, tshwj xeeb tshaj yog rau kev lag luam aerospace thiab aircraft thiab lwm yam kev siv tseem ceeb. Filler hlau yuav tsum tsis muaj hlau thiab tsis yog xim hlau impurities thiab muaj ib tug huv si, du nto uas tsis muaj noo noo, av, lubricants los yog lwm yam kab mob. Yuav tsum muaj kev saib xyuas ntxiv thaum lub sij hawm cia thiab tuav cov hlau muab tub lim kom tsis txhob muaj cov kab mob sib kis uas tuaj yeem ua rau tsis zoo soldering. Baoji City Changsheng Titanium Co tau lav rau nws cov neeg siv khoom zoo tshaj plaws titanium muab tub lim hlau, suav nrog kev sib xws, tsis muaj qhov tsis xws luag thiab tsis muaj paug.

Peb muab cov ntaub ntawv zoo thiab cov khoom siv nws cov khoom lag luam hauv ntau lub hnab ntim khoom ntim rov qab uas tau them los ntawm cov kev xav tau ntawm AMS, AWS thiab lwm yam kev coj ua lag luam, suav nrog lub hnab ntawv vapor barrier nrog desiccant, kom paub tseeb tias cov hlau ntim khoom pub dawb ntev npaum li nws khaws cia hauv thawj ntim.

Lus Cim: Ob qib titanium feem ntau yog kev lag luam ntshiab titanium ASTM qib 2 (corrosion resistant) nrog lub zog ntawm 350 - 450 MPa, thiab lub zog siab dua titanium alloy Ti-6AI-4V nrog lub zog nyob rau hauv lub 900 - 1100 MPa ntau.

Kev lag luam ntshiab titanium alloys:

Tshawb xyuas corrosion kuj thiab txhua yam khoom ntawm ntau qib muaj.

Kev lag luam ntshiab (CP) alloys yog siv dav hauv kev lag luam kev siv vim lawv qhov zoo weldability, lub zog, corrosion kuj thiab formability.

ASTM qib 1 -2 - 3 - 4. ( ) yog cov khoom lag luam ntshiab thiab feem ntau yog siv rau nws cov corrosion kuj. Txhua qib no muaj qhov sib txawv ntawm cov ntsiab lus impurity. Qib 1 yog qhov ntshiab tshaj plaws. Mechanical zog nce nrog qib.

ASTM qib 7 - 11 - 16 - 17 kuj yog alpha titanium nrog palladium, cov qib no muaj kev tiv thaiv corrosion zoo heev, thaum qib 26 thiab 27 muab kev tiv thaiv corrosion ntau dua. Muaj ntau lwm qib xaiv los ntawm.

Thaum vuam CP alloys, koj feem ntau yuav siv cov hlau uas yog ib lossis ob lub PSI lub zog qis dua cov hlau hauv qab. Welds uas yog diluted nrog lub hauv paus hlau thiab micro-kab mob los ntawm lub hauv paus yuav ua rau kom lub zog ntawm weld hlau. Ib qho txiaj ntsig tseem ceeb ntawm kev lag luam vuam cov qib titanium ntshiab yog tias lawv muaj ntau dua 99 feem pua ​​​​ntawm cov titanium ntshiab thiab tsis tas yuav txhawj xeeb txog kev sib cais. Tib yam muaj tseeb rau kev lag luam ntshiab hlau lossis electrodes.

Cov qib tsis sib xws suav txog li 30 feem pua ​​​​ntawm titanium ntau lawm. Unalloyed titanium feem ntau yog weldable, thiab welded pob qij txha feem ntau muaj lub zog thiab ductility. Post weld stress relief annealing yog pom zoo rau weldments.

Daim ntawv thov

Nws muab cov kev daws teeb meem zoo rau vuam titanium thiab tau siv dav hauv ntau qhov kev lag luam uas yuav tsum muaj cov txiaj ntsig ntawm titanium. Lub AWS 5.16 specification muab tus qauv rau kev tsim khoom thiab kev ntsuam xyuas ntawm cov khoom zoo titanium vuam rods, kom ntseeg tau zoo ib yam thiab kev ua tau zoo hauv kev siv vuam. Nws yog dav siv nyob rau hauv kev lag luam aerospace, qhov twg nws yog siv los vuam cov khoom siv dav hlau xws li cav qhov chaw, tsaws iav, thiab cov khoom siv. Nws yog siv nyob rau hauv marine daim ntaub ntawv qhov twg nws superior corrosion kuj yog xav tau los tiv thaiv corrosive los ntawm dej ntsev thiab lwm yam marine ib puag ncig.
