Looks like fun, how 'bout drilling a concave divot in the end of the stationary length, like the top of a golf tee to keep it from slipping out? How many RPM's was this running?
Applying axial force (forging pressure) immediately after rotation stops results in stronger weld. If I were to improve upon the design, I would keep shorter distance between the rotating and stationary elements, which would keep the pieces from wandering, the biggest issue here.
Good job considering that you were working with available materials.
wow, i made one with very little suplies and i am only 12 yo, i spun 3/4 inch shaft with a sissor jack and i made a steel collar over the fixed spindel, abd i cut that away with a grinder and i got prtty consistant welds with it, i made my base a sewer manhole cover and i engine was a 5.5 honda, thanks for the sweet ass video, i sould of made one before i cut it up, the city needed the manhole cover back
Ha, I think what you're referring to as our "bearings" were the nuts we just put the shafts thru for somewhat "extra support." We didn't have any bearings that like at our disposal.
yeah, i meant the nuts. ;) but i think there are better things to use instead that would have given a bit more support and stability to the staffs. however, i cannot think of anything just now. *lol*
How about for the purpose of the experiment, a steel plate anchored/welded to the bottom of the "Test chamber" with an extremely tight fitting hole for the shafts to go through, then so THEY don't get hot maybe just dribble some coolant on them or something from the top? looked good at the end though! big improvement

you better use bearings with center-and then it might work

The best thing to use for a DIY friction welder would be a modified engine lathe.

Great job! I want one!
The two 'guide nuts' could had been welded together in order to reduce the independent travel they had relative to each other.

what your missing is continuous pressure against the stationary rod.

What a waist of time and money by people who who don't know a thing about welding and machine fabrication.
One of the big advantage of friction welding is that you can weld different metal that would be difficult to weld otherwise.
Few year ago I friction weld a steel ball from a ball bearing (ultra hard steel) to a cold roll steel rod (mild steel).
I used a very simple set up on an engine lathe.

What is the application? Destruction of good hand tools?
Need a little more meat in the holdown divices.

very crud. good idea just needs more thought towards perm solutions

that's pretty neat although the bearings were kinda crappy. i think you could have come up with a better solution for that. anyway, nice work!

u guys should just use pillow blocks with the diameter shaft used. Much safer and more effective

No, stupid people call others stupid. Thus, you're among the stupid.

Cool, have you developed this any further? You should try welding stainless and carbon steel together, you get great results.

Haven't really developed it any further. It was just a fun side project for school.
