Lightbulb How to weld two pieces of metal using just friction

This is interesting because it just uses the simple principles of friction and heat to weld two pieces of metal!

Cooldude bhau, can you explain what this metal piece is and what is this type of process called?

Google for friction welding,I have seen this type of welding in my friends factory where they make tin cans.They use copper wire for welding on the joints of the tins.

Re: How to weld two pieces of metal using just friction

this was stuff we learnt in Manufacturing Technology Part II in BE Mech curriculum.....last year in July I saw this in action at NASA Marshall Space Flight Center being used for ISS module...however, the technology is not without associated material science challenges.

I watched Sutradarji posted clip.

Part II in BE curriculum? Rudimentary, I thought. Common knowledge elementary level, I thought. Two metals of similar (insert right word) will form a bond when rigorously heated under pressure. Even I know that. So what do I miss? 2 pieces of asswipes in Sutradarji's now famous toilet will form a bond if provided with an agent (some wetness in this case) and left alone long enough.

Unless this has to do with 2 dissimilar metals of differing (insert the word) ... how do you achieve if so is the case? Couldn't possibly be heat and friction by itself?

It is about welding two different metals together.

That is 5th grade stuff Dhurendharbhai is claiming to have learnt early midway through BE M. curriculum. This makes little sense to me cause even I know it. 2 metals of similar properties (properties for lack of my knowing of right word) will form a close natural bond if provided with enough heat and friction and pressure. This can be achieved without any outside interference, ingredient or a bonding agent. I am rusty. Can 2 metals of differing properties be bonded together without use of foreign agent or welding ingredient? This could perhaps be what he claims to have learnt ... Sutradarji ... do you see my problem?

Re: How to weld two pieces of metal using just friction

For me this was new. As I said I am not a Mechanical or a Metallurgical Engineer. My knowledge of welding is limited to whatever I have seen at regular workshops where they use either a gas torch flame or a electrical rod for welding.
