New friction

摘要

The UK's first fully-approved friction welded coupler has been launched by steel reinforcement specialist Hy-Ten. Using friction-welding technology widely used in aerospace and automotive industries, the HT Welded Coupler claims to offer better productivity, enhanced structural performance and cost savings. Hy-Ten director Richard Webster said, "With our system there is no threading involved - we friction weld the couplers to the re-bar in the factory so they are simply screwed together on site, you don't even have to use a torque wrench". Couplers are rotated at high speed before the re-bar is offered up to the coupler and the friction between the surfaces scours and heats the metal surfaces to fusing point.
