Friction Welding Machines Process & Advantages

Friction welding is a solid phase welding of two similar or dissimilar materials using the heat generated by rubbing of two materials and when the impurities at the interfaces are removed as flash, stopping the relative motion of the components and applying a forge welding force to form a strong metallic bond.


Advantages:

Very short cycle time (few seconds)
Ideal for mass production
Savings in costly material if bi-metallic component
is used (Eg. Drills- HSS/MCS)
Low heat -affected zone and hence semi finished components can be welded
Low energy consumption
No edge preparation, filler meterial, shielding gas, spattering, fumes and radiation
Excellent welding: Joint as strong or stronger than parent material
Metals as diverse as Cu to Al, Cu or Al to steel, Titanium to stainless steel etc. can be welded
