The friction welding of small diameter pipes has a problem where the thrust is easy to excessive and rotational speed is insufficient compared with the conventional friction welding of pipes of about 10mm.
However, we made it possible to friction weld small diameter pipes of about 4mm using improved equipment, improved joint condition and receiving the cooperation from the related companies.

The friction welding thin wall pipes has a problem where the thrust and the clamping pressure are easy to excessive compared with the conventional friction welding of pipes of about 2mmt.
But once again we managed to friction weld thin wall pipes fromφ10×0.9t
