Abstract

Pressure welding appts. uses a welding head moved towards and pressed against the workpieces, plus a generator of heating energy. The novelty is the use of means giving a voltage depending on the welding head speed. The voltage alters when the head touches the workpieces and switches on the heating energy, and an electric signal depending on the head speed is generated and compared with a standard reference value. The heating energy is switched off when the signal coincides with the reference value. The signal is pref. a train of pulses fed to a counter which switches off the heating generator when a specified pulse count is reached. The welding head is pref. driven by a D.C. motor. Used e.g. in ultrasonic welding, for precise control of welding parameters.
