MaTTSuN Posted August 26, 2004 Share Posted August 26, 2004 i was wondering if seam riveting would work the same as welding? I did a seach but didnt see anything on it. Has anyone done this? i saw it somewhere and it made my ears perk up. Quote Link to comment Share on other sites More sharing options...
auxilary Posted August 26, 2004 Share Posted August 26, 2004 what works better: welding a rollbar in, or bolting it in? same principle Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted August 26, 2004 Share Posted August 26, 2004 You would also need to worry about making a seam that could trap moisture causing rust. Riveted seams will move more than a welded one. Thus I would also worry about any type of seam sealing compound losing it's seal. Quote Link to comment Share on other sites More sharing options...

johnc Posted August 26, 2004 Share Posted August 26, 2004 Having just finished seam wedling a 240Z I can say: Yes, but... 1. You would have to use steel rivets (Cherry, Monel, etc.) 2. You'll need to purchase power rivetting equipment. 3. You'll only have access to about 1/2 the places you need to fasten for drilling and rivet setting. 4. It will take at least twice as long to fasten 1/2 as much of the unibody. Othe then those items, sure, you can rivet the seams on a 240Z unibody.

Guest bluex_v1 Posted August 26, 2004 Share Posted August 26, 2004 Planes are designed to flex, expand, and contract too though. Quote Link to comment Share on other sites More sharing options...

JMortensen Posted August 26, 2004 Share Posted August 26, 2004 Didn't most race cars from the 50's (old Jags and the like) have the skins pop riveted on? I don't know why a pop rivet wouldn't work, although I think as John said it would probably be more work to do it. Quote Link to comment Share on other sites More sharing options...
johnc Posted August 26, 2004 Share Posted August 26, 2004 pop riveted Except for unstress aluminum interior panels, no pop rivets are used anywhere on a race car. Structural rivets were (and still sometimes are) used for stressed monocoque panels. Those are usually run in two rows or more in a specific pattern to distributed the loads evenly. The trade names for these kind of rivets are: Q-rivets, Interlock, Monoblock, CherryMAX, Avex, etc. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted August 26, 2004 Share Posted August 26, 2004 I stand corrected. Thanks John. Quote Link to comment Share on other sites More sharing options...
datsunlover Posted August 27, 2004 Share Posted August 27, 2004 I thought just the 'outer skin' was riveted on planes? As in, the framework was welded/bolted together, and then alum. steel 'pop'ed' over the skeleton.. and wouldn't all those rivets (inplace of a bead of weld..) add up to more weight in the end (assuming you do a LOT of it.. like I had to on my Z.. although I welded..?

Doug71zt Posted August 27, 2004 Share Posted August 27, 2004 POP-Rivets are non-structural only. You need a solid-core rivet to stand structural loads. All aircraft structure is riveted - we order rivets by the pound and there are thousands in a pound. Many aircraft alloys are non-weldable, and welded structure is not as easily inspected as a riveted structure. The trail of fretted alumimun "smoke" is easy to spot, whereas a crack in a seam weld is hard to see. As previously stated, aircraft flex A LOT. Riveted structure quite tolerant of flex. Structural repair is relatively easy in riveted structure, not so in welded structure. For a unit-body car, Seam-welding is the ultimate, but has trade-offs. If you prang it, it prangs the whole car, and it won't be as easy a fix. I seam-welded my strut towers and around the upper rear hatch area and A-pillar. Funny, my interior still creaks over large transitions. As for riveting seams in the car, you would be using monel rivets, and as someone who does structural repairs using monel rivets, I wouldn't recommend it. They are hard to pound correctly. Buy a mig welder and develop a useful skill. Hope this helps Doug Quote Link to comment Share on other sites More sharing options...
MaTTSuN Posted August 31, 2004 Author Share Posted August 31, 2004 well it looks like welding would be better, all i need now is a welder and im good 2 go, thanks for all the reply's Quote Link to comment Share on other sites More sharing options...
