Dual Servo Spin Welder User’s Manual

Press (Axial) Speed

The press speed affects the amount of contact pressure between the parts being welded, which is required to generate frictional heat. The larger the speed, the larger the rate of heat rise. In combination with the surface speed, press speed must be high enough to cause melting at the interface as opposed to grinding, but not too high as to damage the parts. Excessive press speed can also lead to stalling of the spin motor as more torque is required to maintain constant spin speed.

The Dual Servo Spin Welder is capable of operating in two different press speed modes. With the Constant Torque Option (in SETUP > WELD tab) disabled, the press speed is constant during the weld. With the Constant Torque Option enabled, the press speed is variable so as to keep the spin torque constant (see Chapter 5). The latter case resembles the operation of a pneumatically driven press, where the press speed is the result of the melt rate under given air pressure and spin speed conditions.

Selection of the optimum press speed depends on the material and joint geometry of the parts, as well as the surface speed. A range for initial experimentation is 0.5 to 2.0 mm/s.

Weld Depth

The determination of the proper weld depth is highly dependent on the application. The weld joint is typically designed for a specific weld penetration. Ideally, the weld is sufficiently deep to produce a strong, hermetically sealed assembly. An excessive depth may lead to the formation of flash (material that is ejected from the joint area during the weld and adheres to the assembly), the drawing out of reinforcing filler material and realignment of the interchain bonds in the weld plane resulting in a weak axial weld joint, and possibly part distortion.
