Yog lawm,7075-T6 txhuas tuaj yeem welded, masGNEE qhia tawm tswv yim tawm tsam nws rau kev siv cov txheej txheemvim muaj kev pheej hmoo ntawm kev tawg thiab poob ntawm cov neeg kho tshuab kev ncaj ncees nyob rau hauv tshav kub- cuam tshuam cheeb tsam (HAZ). Cov teeb meem no feem ntau ua rau cov pob qij txha tsis muaj zog thiab tsis muaj kev ntseeg siab. Txawm hais tias cov txheej txheem welding zoo tshaj lossis tsis yog - cov txheej txheem vuam ib txwm muaj peev xwm muab lwm txoj hauv kev, cov khoom siv fusion welding feem ntau tsis tsim nyog.
Vim li cas Vuam 7075-T6 thiaj li nyuaj
Siab zog, Weldability tsis zoo
7075-T6 yog ib qho ultra- muaj zog aluminium alloy dav siv hauv kev siv dav hlau. Txawm li cas los xij, nws cov chemistry alloy ua rau nws muaj kev cuam tshuam rau kub tawg thaum lub sij hawm fusion vuam txheej txheem.
Thaum tshav kub kub-Teb chaws cuam tshuam (HAZ) Kev tawg
Thaum lub sij hawm welding, khaus cua sov hloov lub microstructure nyob ib sab ntawm lub weld. Qhov no softening tsim ib qho tseem ceeb tsis muaj zog cheeb tsam uas yog provokes ncua cracking -txawm tias thaum lub weld pib tshwm suab- txo cov alloy lub zog thiab kev cia siab rau.
Cov teeb meem nrog Cov Txheej Txheem Vuam (MIG/TIG)
Standard MIG thiab TIG vuam txoj kev qhia txog cov cua sov ntau dhau, ua rau theem kev sib cais thiab muaj kev pheej hmoo siab ntawm kev ntxhov siab corrosion. Raws li qhov tshwm sim, cov khoom siv poob ntau ntawm qhov siab - lub zog muaj zog uas ua rau 7075-T6 xav tau hauv thawj qhov chaw.
Thaum Vuam tuaj yeem ua tau (nrog ceev faj heev)
Friction Stir Vuam (FSW)
Raws li cov txheej txheem sib koom ua ke hauv lub xeev, FSW tsis txhob yaj cov khoom thiab yog qhov tsim nyog rau kev koom nrog 7075 txhuas dua li cov txheej txheem vuam ib txwm.
Nanoparticle-Assisted Vuam
Cov kev tshawb fawb tsis ntev los no qhia tau hais tias kev sib koom ua ke ntawm titanium carbide nanoparticles tuaj yeem pab tsim cov kab nrib pleb - dawb, siab - lub zog welds, txawm hais tias txoj hauv kev no tseem tshwj xeeb thiab sim.
Tshwj xeeb Aluminium Solder Alloys
Qee cov ntaub ntawv muab tub lim muaj peev xwm siv tau rau cov uas tsis yog- cov pob qij txha tseem ceeb, tab sis cov no tsis pom zoo rau kev thauj khoom -cov kabmob lossis kev nyab xeeb- cov khoom tseem ceeb.
GNEE cov lus pom zoo
Rautseem ceeb los yog load-cov ntawv thov kev pabcuam, GNEE pom zoo kom tsis txhob vuam 7075-T6 txhuas tag nrho. Mechanical fastening, adhesive bonding, or component redesign yog cov kev daws teeb meem ntau dua.
Yog tias qhov vuam tsis tuaj yeem zam tau, nws yuav tsum tsuas yog ua los ntawm cov kws tshaj lij uas siv cov txheej txheem siab heev xws li kev sib txhuam do vuam lossis nanoparticle-cov txheej txheem txhim kho, thiab tsuas yog rautsis yog - qauv, siab - kev ua haujlwm zooqhov twg txaus ntshai yog nkag siab thiab tswj tau.
