Ohya Seisakujyo Corporation

Possibility of functional parts by friction-welding different kinds of materials

Our company has an advantage in friction welding.
We shape joined items by grinding before shipping.
We are able to manufacture products from single-piece production to mass production on a consignment basis because of our flexibility as a backstreet workshop.

A feature of our company is the capability of creating conditions while being conscious of the heat input temperature at the time of joining. We meet prototyping and research requests by using a unique system.

Sales Pitch

Only a small number of expensive materials
Functional part creation
Friction welding can join different kinds of materials.

It is now common to compose only the edges of products from expensive materials and to create the rest using inexpensive materials.

Our company joins special alloy materials with products cast from pure copper.
Exhibits strength under a high temperature environment!! The joined part is molten and does not come off!!
Friction welding is a method of joining by atom-level fusion.
Therefore, the melting point raises to one that is close to the base material.

Joined functional parts can be used even under a high temperature environment where adhesive or braze will melt.
Friction welding for desired air tightness
Liquid or air leakage - Low cost preferable even if the quality is not good
Our company can manufacture outside flange shafts, flange nipples, and other parts with large outside diameters, and parts with small outside diameters. We can join the parts to complete products.
This method leads to material cost reduction and process reduction, and results in a great cost advantage for mass production.

Unlike general welding, faces are joined to each other. Therefore, uniform joining from the center to the periphery is possible.
Therefore, there is no need to worry about leakage even in the following cases: 
・Liquid flowing through the part (pipe structure)
・Air flowing through the part

If the joined part is made of the same material and has the same strength, the base material can be fractured.
