Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm riveted, bolted thiab welded?

Riveted tau dav siv nyob rau hauv cov nkoj siv ua ntej World War II thiab tam sim no tsis tas li. Dua li ntawm txoj kev lag luam kev lag luam, niaj hnub no kev tsim khoom siv tseem siv cov riveting, tab sis cov khoom siv niaj hnub no txawv ntawm qhov riveting ntawm cov nkoj ua ntej World War II. Vim qhov xav tau los txo qhov nyhav, qhov feem ntau ntawm cov khoom siv dav hlau yog txhuas thiab composites. Aluminium yog tsis yoojyim rau kev sib tshuam, thiab cov ntaub ntawv sib xyaws tsis tuaj yeem ua welded. Xav tias lub dav hlau yuav tsum yog dej tsis ruaj, riveting yog qhov kev xaiv zoo tshaj plaws rau aircraft kev tsim kho. Cov kev sib txuas tau yog feem ntau tsuas yog siv rau cov av thaj av (vaj tse, txuas hniav, cranes, sib txuas ntawm cov nkoj ntawm cov nkoj / cov nkoj sab nraud). Cov txheej txheem cauj nplaum yog yooj yim tshem tawm, tab sis nws tsis tuaj yeem ua rau dej, thiab cov luj xaum yog nws xeb xeb (dej tuaj yeem tsim tau rau hauv qhov zawj ntawm lub plua plav). Welded yog qhov tsuas yog koom nrog txoj kev siv hauv lub nkoj ua kev lag luam niaj hnub no (hloov lub riveted kiag li) thiab tseem siv hauv kev ua av. Qhov zoo ntawm vuam yog tias nws tsis nqhis dej piv rau qhov sib txuas rau qhov sib txuas. Piv rau riveting, qhov zoo ntawm kev vuam yog ceev thiab qhov zoo ntawm kev siv vuam siv tshuab yog kev txhim khu ntxiv. Lub disadvantage yog tias nws tsis yog yooj yim los rhuav tshem. Nws yuav tsum raug cua tshuab lossis txiav tawm thaum nws raug tshem tawm, uas yuav ua rau lub reusability ntawm cov ntaub ntawv raw.
