.... The American Welding Society categorizes two basic variations of rotary friction welding as direct-drive friction welding (also commonly referred to as continuous-drive friction welding) and inertia friction welding (also commonly referred to as stored energy friction welding). Both methods employ high...

.... On presses that have main motor capacities up to ∼19 kW (25 hp), the adjustable speed drive is usually of the variable-pitch pulley or traction-drive type. Above 19 kW (25 hp), direct-current or eddy-current control devices are preferred. The motor and drive must be totally enclosed to prevent contamination...
