@1944GPW You dare to insult our tecnique?

what an awesome technology.

How many applications have room enough for a machine that size? Also, it looks like part of it is individually made for each diameter of pipe. Is this practical?

I assume that there is a form of electrical induction being used to generate the necessary thermal energy to weld the thin wall pipe. @1944GPW, Why do you need to get fancy when low tech cribbing suffices?

@repdogg69 yeah scrappy grinding. But maybe he knows something we don't, like it doesn't matter. But I was thinking, ow, that guy scraped a problem for someone else to fix.

I suppose this is the new driveshaft on the 2012 F150 ?

most amazing welding technology i've seen to date,i want all my truck's fabbed parts done liek this xD , soo preety and strong xD

Its called "stir friction-welding".The welds, using this technique, are actually stronger than welds produced by fusion-welding.As the name implies, it stirs (forges) the molecules together. It makes the joint look like the rest of the metal (under microscope). Which means the "weld" has the same strength and mechanical-properties/characteristics as the rest of the metal.WHICH MEANS...... u have uniform load/stress dissipation throughout the metal.

bladeliker (December 31, 1969 at 5:59 pm)

but if it forges witout rebinding the metal into fustion would the weld be unsafe over the long period of time and the normal welding say mma when fused togeather with the filler rod would be better over time and more robust ????

where is the spinning bar, inside the pipe?
