T xeev: Qhov zais cia kawg ntawm kev kho cua sov, los ntawm kev tswj hwm meej, nws mus txog qhov siab tshaj plaws ntawm kev ua tau zoo ntawm cov khoom siv. Nws yog qhov tsim nyog rau cov sijhawm nrog kev ua tau zoo heev, xws li aerospace thiab cov khoom siv tub rog.

Kev tsim kho tshiab hauv kev siv tshuab vuam hlau txhuas

Kev siv tshuab vuam hlau txhuas yog ib txoj kev sib txuas kev lag luam niaj hnub no. Ntsib nrog cov teeb meem xws li thaj chaw kub hnyiab, qhov hws thiab kev hloov pauv thaum vuam hlau txhuas, cov kws ua haujlwm txuas ntxiv tshawb nrhiav thiab tsim kho tshiab kom ua tau raws li cov qauv kev lag luam thiab cov kev cai ua haujlwm nruj dua:

3.1 Kev Kos Duab ntawm Kev Vuam

TIG vuam: Tungsten inert gas shielded welding, nrog nws txoj kev tswj lub zog meej thiab cov txiaj ntsig vuam zoo, tau dhau los ua tus sawv cev ntawm kev vuam zoo. Txoj kev vuam no tuaj yeem muab lub zog ruaj khov ntawm qhov kub siab, xyuas kom muaj zog thiab zoo ntawm cov pob qij txha vuam, thiab siv dav hauv cov teb aerospace.

Kev vuam MIG: Kev yaj cov roj inert uas tiv thaiv kev vuam, nrog nws cov peev xwm ua haujlwm tau zoo thiab kev hloov pauv mus rau cov phaj tuab vuam, tau dhau los ua tus pab zoo hauv kev tsim khoom lag luam. Txoj kev vuam no ua tiav cov txheej txheem vuam ceev thiab txuas ntxiv los ntawm kev pub cov hlau vuam tas li, thiab tsim nyog rau kev tsim khoom loj thiab cov kab tsis siv neeg.

Kev vuam laser: Kev vuam laser, nrog nws lub zog ceev ceev thiab kev tswj hwm kev vuam zoo, muab kev daws teeb meem zoo meej rau kev vuam cov khoom sib xyaw ua ke. Txoj kev vuam no tuaj yeem muab lub zog loj hauv thaj chaw me me, ua tiav kev vuam zoo thiab zoo, thiab tsim nyog rau cov chaw tsim khoom meej xws li khoom siv hluav taws xob thiab cov khoom siv kho mob.

Cov cheeb tsam siv ntawm cov hlau txhuas

Daim ntawv thov ntawm txhuas alloy zoo li ib daim duab muaj yeeb yuj, tso tawm hauv ntau qhov chaw lag luam:

Kev lag luam dav hlau: Cov khoom siv aluminium alloys uas tsis hnyav thiab muaj zog ua rau lawv nyiam siv hauv kev tsim dav hlau.
