For dissimilar material joints
Simplification of the welding process, and weight saving of the products, very law temperature atmosphere, ultrahigh vacuum.
For the parts where the difference of thermal conductivity is required.
For the parts where electrical properties and mechanical properties are required.
For the parts where magnetism, Non magnetism, and hardness are required.
For the parts which corrosion resistance and mechanical properties required.
For reducing costs and material saving of expensive metals.( Heat resistance and Corrosion resistance)
For the case other method is not useful(Abrasion resistance and Impact resistance) Patent pending.
*Unsuitable for structural component, since the strength is reduced because of the use of in-between materials.
Friction Welding
The previous page introduces bending tests.
Small diameter, thin-wall friction welding is introduced on the next page.
