а нахера так сваривать?

now, lick it

[hjdkane1]

Thank you for the help. Have a nice day

[hjdkane1]

Is it possible to use friction stir welding to weld off cuts of a copper coated mild steel rod together to make an earth rod?

[dougw246]

@hjdkane1 The application you describe is excellent for rotary friction welding. You will have a discontinuity in the copper coating at the weld interface.

[dougw246]

easymover1: If liquid metal comes out, you definitely went too fast. The proper friction weld never melts the material, it plasticizes it to create a forging. That is what makes the bond almost as strong as the parent material. Also, in the weld shown, it is using the inertia from the flywheel to transfer energy into the weld interface. Thus, it is slowing down constantly until all of the energy is transferred and the weld is complete.

[dougw246]

RonsTVRepair: The answer is sort of. A lathe does not have the force control required to load the interface with the tons of force needed. Also, the spindle bearing in a lathe are not designed to absorb tons of axial force. Thus, you may be able to get it done, once or twice.

[chewser117]

This is awesome, but what would you use that on?

[qwertzu3]

@chewser117 to create longer pieces of round steel ofc.

[dougw246]

@chewser117 There are numerous applications. The one shown is for making hydraulic cylinder piston rods. If you are interested in more, go to our website. Google Manufacturing Technology friction welding.

[engineer9673]

@chewser117 they use this process in making the axles for land rover. the end flanges are friction welded. look under any landie front axle and you will see

This song makes me feel like a winner.

[foamquilted]

Well at least this isn't soundsystem 

[jiniton]

amazing background music

[easymovet]

it needs to slow down at the end to prevent ejection of liquid metal by centrifugal force.

[Kimbley26]

@easymovet as far as i Know this process is solid state welding, you only see Plastic deformation ._. correct me if I'm wrong

[captainLAGER]

Music in a youtube video? How is this not already blocked in Germany?

[RonsTVRepair]

Can this be done with a regular lathe?

[Fragite]

@RonsTVRepair hell no.

[PeteforPrez]

i love this soundtrck!



[IntrepidMoocher]

Anyone know the name of the song!?!

[inagod]

Is the weld as strong as the surrounding metal,how about adding little round disc's, of different alloys into the mix to make a stronger weld,joint?

[dougw246]

@inagod The weld is as strong as the parent material in most cases. There has been work done on third party alloys and it does work.

[tn21beer]

Thats impressive.

[ishouldplayzelda]

lol that's so cool

[RifledBarrel]

I can understand the friction part but what's it got to do with inertia?

[dougw246]

Friction is the method for generating the heat. In rotary friction welding the energy source for the frictional heat commonly comes from one of two sources. Either an electric motor that is continuously driving the rotation or the kinetic energy stored in a rotating flywheel as defined by 1/2 (Moment of Inertia)*(Angular Velocity)^2.

The second method is known as inertia welding. I hope that helps.

[rockyPants4000]

@RifledBarrel To simplify. Inertia (energy stored in the spinning flywheel attached to the left side piece) is used to spin that piece as it touches the other piece. When that kinetic energy is used up, the piece stops spinning and the weld is complete.

I do not know why kinetic energy is used in some cases, and direct motor energy is used in others.

Alternatively you can use a motor to keep the piece spinning through the entire process.

[Knnniggit]

@rockyPants4000 re: "I do not know why kinetic energy is used in some cases, and direct motor energy is used in others."

It seems to me that a direct-drive spindle would have to draw a lot of electrical power in a short period of time. In other words, the peak load would be much higher. In a shop with lots of machines, that instantaneous power loss could be unacceptable, i.e. machines would shut down. For heavy duty work, a flywheel would eliminate that issue.

Disclaimer: I am not an expert

[videotater]

@Knnniggit I think you're on to something. You can keep spinning the flywheel faster and faster, even with a puny energy input, if you are patient enough to wait for it to come up to speed. Then, you "dump" all that stored energy (stored in the rotational energy of the flywheel) into the parts to be welded, all of a sudden. Lotsa heat, right away.

[pfconcolor]

@Knnniggit You are correct wrt electrical power demand. In addition, the integrity of the weld depends upon uniform rotation of the work piece. When you squash the two pieces together to create the friction, this greatly increases the load on the motor. Unless it is well over-sized (and overpriced), the motor may not be able to handle the extra torque, thus compromising the weld. The massive flywheel smooths out motion and allows the use of a more appropriately sized motor as well.

[YoungJim409]

No longer than it needs to be, and a very good description of the process.

[chainsawz]

whats with the music? lol

[omniwelder]

I saw this on a video when I did my welding course at college. I thought of it as bizarre how quickly it happens.

[lordtaw]

Thanks for that quick and simple video on friction welding.

[shataizzle]

:D amazing!!!

was helpfull

thx..
