Al 6061 Fsw !

This is a pretty stupid video. A demonstration of friction stir welding, where they don't actually weld anything, just destroy a chunk of metal. I suppose it shows the power of a very fast spinning bit and some gentle pushing. This leaves the welding to the imagination. I could already do that! I want to see 2 pieces of separate metal being joined using a stirring-based friction method! Then I want to see an attempt to pull the 2 pieces apart, which fails, because they're welded. That would be a real-life demonstration of an interesting and powerful technique. But this is just a bloke ruining a perfectly good bit of metal. They had the expensive machine right there, they had one piece of aluminium. All they needed was one more piece! That's all! Then they could've actually shown some welding! And what the joint would look like, and how it could stand up to stress. But no! We get aluminium welded to nothing while being halfway buggered. Thanks a lot, KZbin!

That's lovely but how about showing two pieces that are not already joined then show the results under an X-ray machine?

Delirante...

what would be good to see is a microscopic cross section of the weld.

change the title dude it's FSP (friction stir processing)

I see and think I understand how this process works but are the two pieces of aluminum clamp together with lots of force before welding this way? If not how are the pieces held to resist the force of this type of welding? What causes the part not to flex with the amount of heat being placed on them?

this is friction stir processing

What's the material used in the welding pen

GO MSU!!!

is that a gumsten tarbide bit?

I am wondering about this process, as in the context of joining two cylinders. The plunge of the tool creates an origination point in the weld but what about joining two cylinders with one continuous weld? It would seem that the tool would need to rotate around the whole cylinder and past the starting point to insure uniform weld properties.

on which material friction stir welding done eat??

Aluminium*

it seems more to be a friction stir processing that isn't used to weld but to get harder metal using the advantages of that type of welding process. The result is a finer grain of the microstructure and so better mechanical features.

this is our final year project

HELLO, congratulation for your nice job. I am working on that process but I have some diffucties to realise a good surface. Could please provide some informations? What is the rotation speed (rpm) , feed rate,linear speed, diameter of your tool etc ... thank you very much and good job again

Wondering if the slag is easily removed and the surface condition of where it lands. Also does not look like it is possible to weld up to a shoulder, flat parts only?

Actual weld here. The metal is cratered/broken - a large gap is made. It's then filled immediately with molten metal while all under the cover of the drum. Is our imagination...lacking? Having imagination differs us greatly from other mammals.

In order to do an actual weld would require additional clamps which they may not have at the time.

Soooooo what was welded here? I see a spinning bit going through a solid piece of aluminum.

This is amazing. How soon before one piece of metal can be drill, welded, milled and whatever else with the end result being a completely finished product from a single piece of metal? As in, not a piece of something, a working finished thingamajig. haha

HACKS

saw

Nice Camera! ;D

it looks like Bilo has gotten hold of the CNC machine again....

Metal bonded together through a melting process.

And nothing was welded on that day.

Hello, what is the difference between FSP and FSW ? thank you

Wow, looks surreal!
