Puas yog 7075 Txhuas Yooj Yim rau Weld?
7075 aluminium alloy yogtsis suav tias yooj yim rau vuam, tshwj xeeb tshaj yog thaum piv nrog cov alloys xws li 6061 lossis 5083. Qhov kev sib tw tseem ceeb los ntawm nwssiab zinc thiab tooj liab cov ntsiab lus, uas ua rau kom muaj zog tab sis kuj ua rau muaj kev pheej hmoo ntawm kub tawg thaum vuam.
Thaum cov txheej txheem sib xyaw ua ke, xws li TIG lossis MIG vuam, 7075 txhuas zoo li poob nws cov khoom siv hluav taws xob hauv tshav kub- thaj chaw cuam tshuam (HAZ). Tsis tas li ntawd, welding tuaj yeem txo qhov kev tiv thaiv corrosion thiab qhia txog qhov tsis xws luag. Vim li no, cov qauv vuam dav dav yogtsis pom zoorau kev thauj khoom tseem ceeb-cov kabmob ua los ntawm 7075 txhuas.
Hauv kev xyaum ua lag luam, 7075 txhuas feem ntau yogmachined los ntawm cov hlau nplaum los yog forgingsntau dua li welded. Thaum koom nrog, yuav tsum muaj lwm txoj hauv kev xws li kev siv tshuab fastening lossis tshwj xeeb vuam cov txheej txheem.
Vim li cas Kev Tiv Thaiv Vuam Pom Zoo rau 7075 Txhuas?
Kev tiv thaiv vuam feem ntau pom zoo rau 7075 txhuas vim nwstxwv cua sov nkagthiab txo metallurgical puas. Tsis zoo li arc vuam, tsis kam vuam concentrates cua sov ntawm qhov sib koom ua ke thiab siv lub siab ib txhij, txo cov zinc evaporation thiab tawg.
Cov txheej txheem tswj hwm no pab khaws cia lub alloy lub zog txhua yam thiab txo qhov cuam tshuam. Raws li qhov tshwm sim, kev siv vuam tsis kam yog dav txais hauv cov ntawv thov uas txwv kev koom nrog tsis tuaj yeem zam, tshwj xeeb tshaj yog nyob rau hauv aerospace thiab siab - kev ua haujlwm ntawm kev tsim tsheb.
Raws li cov qauv kev lag luam thiab cov lus pom zoo los ntawm Lub Koom Haum Aluminium, kev siv vuam tsis kam muabcov txiaj ntsig zoo sib xwsthaum ua haujlwm nrog siab -lub zog aluminium alloys xws li 7075.
Puas Vuam cuam tshuam rau lub zog ntawm 7075 Aluminium?
Yog, welding muaj ibtseem ceeb cuam tshuam rau lub zogntawm 7075 aluminium. Thaum tshav kub kub generated thaum lub sij hawm vuam yuav yaj lub zog precipitates tsim thaum tshav kub kub kev kho mob, uas ua rau ib tug softened cheeb tsam nyob ze ntawm lub weld.
Qhov kev txo lub zog no tsis tuaj yeem rov zoo tag nrho yam tsis muaj re-kev kho cua sov thiab rov- kev laus, uas feem ntau siv tsis tau rau cov khoom loj lossis cov khoom siv. Yog li ntawd, welded pob qij txha hauv 7075 txhuas feem ntau nthuav tawmqis zog tensile thiab qaug zog kujtshaj cov khoom siv hauv paus.
Vim li no, engineers feem ntau tsis txhob vuam 7075 txhuas nyob rau hauv siab - kev siv kev nyuaj siab thiab es tsis txhob cia siab rau bolted, riveted, los yog machined designs.
