Puas yog 6061-T6 Aluminium Weldable?
Yog. 6061-T6 yog ib qho ntawm feem ntau welded aluminium alloys thiab tau koom nrog hauv kev tsim khoom los ntawm cov pa roj tungsten arc, roj hlau arc, tsis kam thiab kev sib txhuam do vuam. Cov hlau tseem tuaj yeem raug welded rau lwm qib 6xxx thiab 5xxx nrog cov hlau tsim nyog.
Qhov tsim nyog tseem ceeb yog qhov vuam tsis khaws T6 temper. Lub tshav kub ntawm lub arc overages lub tshav kub- cuam tshuam cheeb tsam, thiab vim hais tias txhuas ua cua sov sai heev uas cheeb tsam yog dav. Lub vuam hlau nws tus kheej yog cam khwb cia 5xxx lossis 4xxx muaj pes tsawg leeg, thiab thaj tsam softened ib sab nws yog qhov txwv ntawm qhov sib koom ua ke. Cov neeg tsim qauv yog li ntawd xaiv 6061-T6 rau welded fabrications tsuas yog thaum lawv tso cai rau qhov txo qis hauv zos.
Cov txheej txheem vuam ntau rau 6061-T6
| Txheej txheem | Yam ntxwv | Hom kev siv |
|---|---|---|
| GTAW / TIG | Hloov tam sim no nrog siab - zaus pib, argon shielding, zoo tshaj plaws thiab tswj, qis tshaj deposition tus nqi | Cov ntu nyias, pom cov pob qij txha, kho cov haujlwm, cov hauv paus hla |
| GMAW / MIG | Pulsed los yog tshuaj tsuag hloov mus, siab deposition npaum li cas, spool-rau- phom los yog thawb- rub hlau pub | Ntau lawm vuam ntawm nruab nrab thiab tuab seem |

| Kev sib txhuam do vuam | Khoom-txheej txheem txheej txheem, tsis muaj melting, khaws cia deb ntawm niam txiv-hlau lub zog, xav tau cov cuab yeej nruj | Siab dua -cov pob qij txha muaj zog, cov vaj huam sib luag thiab cov qauv khov kho |
| Laser thiab electron beam | Cov cua sov nqaim heev- thaj tsam cuam tshuam, tus nqi peev siab, sib koom ua ke- nce qhov tseem ceeb | Xaiv qhov tseeb thiab siab - daim ntawv thov ntim |
Oxy- roj welding yeej tsis siv, thiab thaiv cov hlau arc vuam nrog coated electrodes yog tsis siv rau cov qauv txhuas pob qij txha. Kev sib txhuam txhuam vuam yog tib txoj kev dav dav uas ua rau ib feem tseem ceeb ntawm T6 lub zog nyob rau hauv qhov sib koom ua ke, uas yog vim li cas nws thiaj li siv rau cov pob txha txhav thiab cov rooj sib txoos loj.
Filler Hlau Xaiv
| Filler | Kev sib xyaw | Tus cwj pwm ntawm 6061-T6 |
|---|---|---|
| TIAB SA 4043 | Al-5 Si | Fluidity zoo heev thiab qhov tsawg tshaj plaws solidification cracking txaus ntshai, tab sis qhov qis tshaj kev sib koom ua ke lub zog thiab ib tug tsaus nti anodized tsos |
| TIAB SA 5356 | Al-5Mg | Siab zog thiab zoo toughness, zoo dua xim match tom qab anodizing, me ntsis siab dua tawg rhiab heev nyob rau hauv ib co kev sib koom tsim |
| TIAB SA 5183 | Al-4.8Mg nrog Mn thiab Cr | Siab - lub zog muab tub lim siv qhov sib koom ua ke lub zog yog qhov tseem ceeb thiab lub hauv paus hlau tso cai rau nws |
Tsis muaj cov hlau muab tub lim rov qab T6 lub zog ntawm lub hauv paus hlau, vim tias lub zog yog nyob ntawm nag lossis daus hardening uas vuam puas hauv zos. Cov kev cai siv tau yog siv ER4043 qhov twg tawg tsis kam thiab zoo li qhov teeb meem thiab ER5356 qhov twg lub zog thiab toughness tseem ceeb dua, thiab xaiv cov muab tub lim tsuas yog tom qab kev sib koom tsim thiab cov kev pabcuam thauj khoom paub.

Cov lus nug nquag
Q: Puas tuaj yeem 6061-T6 aluminium alloy welded?
Yog lawm. Nws yog niaj hnub welded los ntawm TIG, MIG, tsis kam thiab kev sib txhuam do vuam, thiab nws tseem tuaj yeem koom nrog rau 5xxx thiab lwm qib 6xxx nrog cov hlau tsim nyog.
Q: Dab tsi muab cov hlau yuav tsum tau siv rau 6061-T6?
ER4043 yog qhov kev xaiv ib txwm muaj qhov tawg tsis kam thiab zoo li qhov teeb meem, thiab ER5356 lossis ER5183 qhov sib koom ua ke muaj zog thiab tawv tawv ntau dua. Kev xaiv yuav tsum ua raws li kev sib koom tsim thiab kev pabcuam thauj khoom.
Q: Puas yog vuam txo lub zog ntawm 6061-T6?
Yog lawm. Thaum tshav kub kub- thaj tsam cuam tshuam yog overaged thiab poob ib feem loj ntawm T6 lub zog, yog li cov welded sib koom ua ke tsis muaj zog dua li cov niam txiv hlau. Qhov kev txo qis yog tso cai rau hauv kev tsim ntau dua li tshem tawm los ntawm kev siv vuam.
Q: T6 puas tuaj yeem rov qab tau tom qab vuam?
Tsuas yog los ntawm kev daws teeb meem tag nrho thiab rov- kev laus ntawm tag nrho lub rooj sib txoos, uas tsis tshua muaj txiaj ntsig vim muaj kev cuam tshuam. Cov cua sov hauv zos tsis tuaj yeem rov qab los ntawm kev npau taws, thiab kev laus ntawm qhov chaw vuam ib leeg tsis tuaj yeem rov qab los ntawm niam txiv -cov khoom hlau.
Q: Puas yog kev sib txhuam do vuam zoo dua MIG rau 6061-T6?
Kev sib txhuam do vuam khaws cia ntau dua ntawm cov niam txiv-hlau lub zog vim nws tsis yaj cov hlau, thiab nws ua rau muaj kev cuam tshuam tsawg dua. Nws xav tau kev txhawb nqa nruj thiab kev siv cuab yeej, yog li nws raug xaiv thaum kev sib koom ua ke ua kom pom tseeb tus nqi.
Q: 6061-T6 puas tuaj yeem welded rau stainless hlau lossis 7075 txhuas?
Fusion vuam rau hlau tsis pom zoo; yuav tsum tau siv ib qho kev hloov pauv bimetallic lossis ib qho kev sib koom ua ke. Kev koom nrog rau 7075 tseem raug zam hauv kev pabcuam kev ua haujlwm vim tias muaj kev pheej hmoo ntawm kev tawg thiab corrosion.
Q: Dab tsi ua rau tawg thaum vuam 6061-T6?
Cov laj thawj feem ntau yog cov hlau tsis raug, cov pa paug los ntawm cov roj lossis oxide, kev txwv ntau dhau, cov khoom siv hluav taws xob ntau dhau thiab tsis haum- nce. Kev xaiv cov muab tub lim kom raug, ntxuav qhov chaw thiab cov txheej txheem tsim nyog tiv thaiv kev tawg feem ntau.
