Friction Welding
What is Friction Welding ?
By rubbing two workpieces together to generate frictional heat and applying pressure, the structures of each workpiece are bonded at a molecular level. Joining dissimilar materials is also possible.
The components to be joined are rubbed together at high speed and then joined using hydraulic pressure. (Solid-phase bonding)
Advantages of friction welding
Joining dissimilar materials
Friction welding allows for the joining of dissimilar metal materials with different properties. By utilizing and combining the necessary properties of materials—such as high and low cost, hard and soft, heavy and light, magnetic and/or electrically conductive—unique parts can be designed. ~Multi-material~
a. Diversification of design
We will need to create prototypes for the material combinations, so please feel free to contact us.
b.Reducing material costs
Since it can be used only where needed, rather than being machined from expensive materials, it leads to cost reduction.
Productivity optimization
Compared to conventional machining methods, this approach can reduce costs and time.
By joining parts of different outer diameters using friction welding, the amount of material removed is significantly reduced, and the process consists almost entirely of shape cutting.
a. Reduction of processing time
Conventional machining processes resulted in significant losses in processing time and material.
By combining and joining standard-sized materials, the amount of material that needs to be removed can be minimized.
b. Lightweighting of parts
By hollowing out the inside or by combining and joining lightweight materials in certain areas,
This will allow for a reduction in the weight of the product.
→Suitable for machining roller shafts and similar components.
c. Joining parts with different processing methods
It is also possible to press-weld dissimilar materials (or the same material) to parts that have been processed differently, such as attaching a stainless steel shaft to an aluminum casting.
d. Automatic angle position control
It is also possible to stop the rotation at a reference position on the axis of rotation, such as with D-cuts or grooves, and then join the parts.
High stability and reproducibility
Since the joining process is NC-controlled (numerically quantified) using a friction welding machine, the quality of the finished product does not vary depending on the person performing the welding. The know-how of friction welding lies in the setting conditions for joining and how to understand the workpiece. Therefore, once successful, the reproducibility of that joining is extremely high.
A manufacturing method suitable for mass production
Even when comparing the cross-sections of joints formed by conventional welding, friction welding produces a more uniform and stable joint surface.
