Friction welding API drill pipe for oil exploration

[geetarwanabe]

wow just reading about this in my materials and manufacture course. I read "friction spin welding" and saw a retarded illustration of one box stationary and another with a circular arrow. Turns out thats exactly what happens lol.

Really impressive!

[ToCad0]

how many rps is used?

[joemanses]

why doesn't the metal start to deform when it becomes that malleable?

[Sprengstoff]

really cool, or actually pretty hot :) But what happens on the inside of the tube? will there not be a bulge og ridge in there that will constrict the flow through the pipe?

[cummins245]

@Sprengstoff The inside of the tube is smooth. The centrifugal force of the welding process forces the bead outside. Smoothest and most effective weld there is!

[MsSpy]

I wonder if this creates a brittle heat affected zone at the weld point.

[marrabooboo]

@MsSpy in short its harder than the parent material but not brittle in this instance, the pipes are heat treated with an induction coil at the next stage in the line.

[slapleatheru3]

Wow! That was awesome!!

[neato3000]

Wonder if it sounds as bad as I can imagine?

[TheLightningStalker]

This is beautiful.

[marrabooboo]

HDDdriller, Upset or no upset FRW is far better than any fusion bonding method

[vatoloko5000]

and as it is on the inside it reduces the inner diameter?

[epistte]

That has got to require serious HP to generate the necessary friction and the hydraulic pressure to force the tool joint and the pipe stem to weld together w/o outside material or energy.

[HDDdriller]

Without upset on tube ends this connection is shit.

[marrabooboo]

@HDDdriller the pipe in the video is 5inch API IEU grade S so yes it has upset on both internal and external diameters. With all due respect to your comment, diamond pipe has no such upset internal or external and when tested underr the correct conditions both as an assy or section the parent material is the first to fail effectivly rendering the joint stronger than the tube. in short the geometry of the weld interface has little or no effect on the bond performance. i have data to support this

[Taketheride23]

That gives me some goosebumps!

[AMACTAGGART5]

do the pipes need machined internally after this process? it is very impressive tho!

[spencerstheshit08]

thats some cool stuff, if we had this where i work we would get a hell of alot more work done lol

[BUNGLEJYME]

The advantage using this type of welding is you get complete joint penetration.

I wonder if you can join dissimilar metals this way?

[cesky69]

ha ha ... you said complete joint penetration

[BGleaves123]

@BUNGLEJYME - I believe that's one of the main advantages of friction welding - joining dissimilar materials.

[K3N7CR1P3]

@BUNGLEJYME you can. check out [wikipedia org/wiki/Friction_welding#Bene­fits] (add period)

[georgecprn]

@BUNGLEJYME yes you can, and it's the best way to do it. you can weld even copper to aluminum, titanium to copper, and nickel alloys to other steels.

[polarrhoid]

@BUNGLEJYME Absolutely. Here's a tool that shows some of the dissimilar metals you can join via this process (and other forms of friction welding, such as friction stir and linear friction welding.)

[T2DMF9000]

read about it in my welding textbook but after seeing it in this video it is very bizarre! what a strange way to weld 2 pieces together

[robietrav]

i really enjoyed that....i didnt learn that type of welding back in school...haha

[harismokhtar]

@robietrav actly its quite new actly, around in 1990's.. but i learn it in my cluz.. : )

[odlavinbnx]

Met a machine of 32 years ago. If called INERTIA WELDER Made in USA and worked in Equipetrol, a Brazilian company that manufactured equipment for petroleum.

[odlavinbnx]

I work company 32 years ago thad do it. The machine named INERTIA WELDER. The machine made USA and the company was EQUIPETROL

[TimeLapseSteve]

That was really cool.

[Ikeweemering]

Do you have any x-ray graphs of it

[marrabooboo]

this is a solid state 100% cross section bond so all you would see is a solid chunk of metal

[Ikeweemering]

thanks for your reaction but i think its a pipe to pipe fitting watch just before the pipes meet you can see its hollow

[marrabooboo]

What I mean by solid state is that the parent material is not heated past its melting point; the HAZ of this pipe is in a semi-solid plastic condition during the weld. And by 100% cross section, I mean that the entire cross sectional area of the tube is welded to form one solid tubular section. Therefore if you X-ray it you would only see a solid tubular section with no voids or inclusions that would be visible using this method of NDT.

[Ibringthetruth1]

how cheaper than mig?

[marrabooboo]

MIG needs weld prep and clean up where friction welding does not, so in some cases it can be 100 times faster considering the new thompson machines can make a ready to go pipe in less than 90 seconds!

[sureshsorathia]

good video

sir can u send other friction welding of drill pipe video

[Antriebswellenkiller]

Very nice video !
