Default Welded Pushrods

To see a number on photos showing preparation and finished welded push rods go to my post here, along with a number of informative posts regarding the process.



I have been flying with these in my RV-7A for six years now with no issues.

There's certainly nothing wrong with welding them in, but the riveted versions will work fine, too. Regardless of how they're attached, you *still* have to ensure that there's no chafing or binding anywhere, and that may require relieving one or more pass-throughs throughout the airframe. You just may have to relieve it a little more if the rod ends are riveted in, that's all.

Welding won't obviate the need to ensure the systems is free of chafe points or the like.

Default two if by welding... one if by...

So If I have them welded, can I proof load test them?

How much weight should I hang from the ends to proof test the welds?
what is twice the expected flight loads in tension?

Wow, are there rivets all the way around, 90 degrees apart, staggered 45 degrees between the inner and outer rows, for a total of eight rivets?

I wonder if welding of the control pushrod is a non-standard aviation practice. It seems using rivet is standard, and according to Vans and Airbus. I wonder if Mel will ding you if you weld.
