Comparison between friction welding and conventional technology

Here we introduce cost savings realized by friction welding, as well as the merits of adopting friction welding over conventional technology.

Outstanding Cost Savings

Friction welding of same material with different diameters

Material costs and machining costs are reduced compared with cutting.

Friction welding of dissimilar metals

Cost savings are realized by using expensive material only for necessary parts, and inexpensive material for other parts.

Workpieces for which integrated machining is difficult

Machining workpieces separately and integrating them with friction welding makes the process easier.

Minimal loss

Stable, high-quality production is possible, achieving a high yield ratio even for expensive material.

Streamlining of previous and next processes

There is no need for previous processes such as groove or spigot, allowing processes to be significantly streamlined.
