– Riveted structure has better fatigue strength and is easier for repair than welded structure.
– Rivets increase strength, because they are expanding during riveting and the hole’s edges are internally herdening.
Welding joint always decreasing strength.
Also if cracks are appearing, riveted structure is better, because the hole can stop those cracks.
Of course production time is long, is necessary to drill pilot holes, after that redrill, deburr, countersunk holes (for countersunk rivet heads) and rivet (make closing heads).
please read an structural-materials book…..
No, he is right. You should.
SOC
Plus MiG did notice that there was a shortage of experienced riveters at the time, so welding was the logical choice.
Noooooo SOC, not again buahhh this is (i think) an construction-design thread, not an foxbat thread, the russians are not soooo stupids to make an riveted steel plane (maybe are exeptions, maybe)
About the topic.
Yes the Al is hard to weld (because that stupid oxide layer)so the only practical solution are rivets, the riveted unions reduce the transverse piece area, the rivets increase the deformation “pressure”,etc,etc,etc,etc,etc,etc,etc,etc,etc,etc,etc,etc,e tc,etc,etc,etc,there are more blablablablabla comparing welding/riveting, but im tooo lazy to say all, ,a question (for who knows), you can weld aluminium with argon-plasma arc????
Actually welding weakens higher grades of aluminum. And maybe you would like to fill in some bla blas instead of hiding behind assumed knowledge.
PLA
You guya forgot the most important one… Glueing… Fokker was famous for that.
Interseting, maybe is the same compositives concept??????
Or maybe just the laminated wood days.
