The story about the welding rod for 7075 was interesting, also within the story was story about drones being developed for armies, equipped with weapons. Labeled as "Boots off the ground". Looks like a good way to save some a lot of our soldiers lives. Learned two things from one thread.

LOL I was just about to post the earlier thread, Thanks E T

 

This is why STEM is just as important as vocational occupations. They go hand in hand.

 

Wow, that's a game changer.

 

Lots of technical reading. It opens a new world of fabrication. Cars boats and airplanes.

Somewhere it said the samples were welded with a welding robot. That takes the operator out of the picture once the robot is set up.

Now for us “poorer people” who haven’t moved up to the automated welding, leave welds with various qualities not covered in the text. In other words the weld puddle may be micro stirred slightly different in each bead. I wonder how this effects the finished weld. There could be small cracks slowly developing. And maybe not if the puddle is stirred well enough.
Somewhere it noted that the rod was laid down in the weld joint and fusion welded. I think there will be some inconsistencies here too. I’m not being negative at all. It’s great news but average TIG guy in the shop is going to have to understand how this stuff works or there maybe good and bad welds that look the same.

I hope to see this technology soon.

 

I prefer AL tig to be done by people who do it daily.I "can" do it.........what for ?
