Abstract

Aluminijum je posle čelika najznačajniji građevinski material, iako nema dugu istoriju primene u građevinarstvu. Građevinske konstrukcije od aluminijuma potencijalno mogu naći veliku primenu zahvaljujući dobroj korozionoj postojanosti, lakoći legure, otpornosti na krti lom itd. U ovom radu opisan je uticaj zavarivanja trenjem sa mešanjem na strukturne i mehaničke karakteristike legure aluminijuma 2024 T351. Uzorci koji se zavaruju su ploče debljine 6mm. Zvarivanje je izvršeno glodalicom pomoću posredstvom posebno oblikovanog alata. Ploče su zavarene u tri različita režima parametara, pri čemu je rotacija alata u svim slučajevima bila 750 min-1, a menjao se posmak alata, 73 mm/min, 116 mm/min, 150 mm/min. Svi uzorci su zavareni bez grešaka i prekontrolisani radiografski i vizuelno.
