Latest model Friction Welding machine
Friction welding machine. No electric arc, spark, smog, or toxicant generated because no fuel or filling material is needed at the time of processing.
Friction Welding Flowchart
Friction welding flowchart. No need external heat or additional welding rod. Heat is evenly distributed among surface of items.
Welding Process.
Friction welding tension test. It shows the strength of welding point is equal to or greater than the original two pieces.

The tension test shows that the welded unit fails somewhere other than the welded point.

PRINCIPLE

It is that one "solid state" welds the method, it regard frictional heat as the heat source, motor via the rotation friction of the relativity and exert the axial pressure, heat the work piece surface to the plasticity state, construct and join the same kind or the different kind of metal firmly with the pressure at the same time.

CHARACTERISTIC & ADVANTAGE

  1. No external heat or additional welding rod is needed. Heat is evenly generated and distributed between the surfaces of work pieces.
  2. The strength of the welding point is greater than the or original material(s). The welding is conducted with high accuracy without altering the properties of the original material(s).
  3. No electric arc, spark, smog, or toxicant is produced because no fuel or filling material is necessary at the time of processing, which leads to a better working environment.
  4. Compared to other types of welding, the surface is cleaner because of the shifting friction and replacement of the surface layer.
  5. Friction welding can be conducted with extremely high efficiency, which makes it especially suitable for automation for mass production.
  6. Friction welding has become one of the most reliable and economical methods of jointing metals. It has been extensively applied in order to reduce the cost of production and improve the quality of welding.
  7. Friction welding can be applied to most engineering materials. Different metals can also be effectively jointed using this method. The relative sliding displacement after welding is minute and can fulfill any testing requirement.
  8. In most cases, the strength of the welding point is equal to or greater than the original two metal pieces.
