Very true.Most on an airplane is riveted and bolted together.
Some exotic friction stir weld surfacing now..... but most is bolted and rivited.
Surprisingly little welded on 10 Ton class part 25 jets
Fully agree.Very true.
However there are a ton of welded boats running around that essentially live in vibration due to the engine and waves.
It would be hard to find a weld on a plane....lots of rivets though.You mean like airplanes?
Point loading happens when there isn't enough internal structure to support the hull plate for a given speed and weight. For this reason cracking happens alot.A welded boat hull has much less point loading than a framed vehicle chassis. Boats also have less weight concerns, and can have significantly higher factors of safety.
The stresses that cause cracking of aluminum welds on a bumper are far less than those encountered by an aluminum trailer. Apples and OrangesAn aluminum bumper saved me from serious injury in a rear end collision that totaled the vehicle. Sure, so would a steel bumper but at significantly more weight, not to mention greater corrosion risk. IMHO, aluminum done right is more than adequate for vehicle modification.
My steel trailer with a steel deck has been sitting outside uncovered for almost 20 years. Rolled a new layer of rustoleum on the deck last year, but other than that it's fine.Thx again all. Good points all around. Steel guy not responding. Did some measuring in garage, this may be stored outside. For that, leaning aluminum. No extreme use.
