A welding method for welding a first component to a second component using a welding device including an upper tool mounted to an upper support for receiving the first component, a lower tool mounted to a lower support for receiving the second component as well as a preheating arrangement for preheating the first and/or the second component and a controller. A welding device in accordance with the welding method is further provided.

Welding method and respective welding device

A welding device with which two components can be pressed against each other comprises a static first section and a second section movable relative to the first section. At least one drive system is connected at a first end to the first section and at a second end to the second section, as well as at least one elastic guiding system by which the first section and the second section are connected to one another. The first section and the second section are movable relative to each other along only one axis due to at least one elastic guiding system, so that an axial length of the arrangement can be varied. A moving coil drive may be used or another drive without mechanical losses or with mechanical losses less than a clamping force to be applied during operation.

Welding device positioning arrangement

The present invention discloses a heat radiator, especially an infrared radiator, having at least one radiation source by means of which supplied electrical energy is convertible into heat radiation, as well as a control. This control comprises at least one frequency converter having a first, a second and a third output so that between the first and the third output a first alternating current is providable and between the second and the third output a second alternating current is providable by means of which the at least one radiation source is operable.

Heat radiator, device for infrared welding and method for heating plastic components

The present invention relates to a method for vibration welding. The vibration welding is performed with a plurality of mechanically decoupled oscillating heads, each of which is connected with a frequency converter. An electrical circuit connects the frequency converters such that one of the frequency converters can be operated as the master and the other frequency converters as slaves. With the help of the controlling effect of the master, both a synchronous and a targeted asynchronous operation of the plurality of oscillating heads can be realized.

Apparatus and method for vibration welding

The invention relates to a method for adjusting the operating frequency of a vibratory welding system producing orbital motion comprising a workpiece socket head which is mounted to resilient means. The head is driven by electromagnetic means to produce orbital vibrations to be constricted to a vibratory plane for welding workpieces, in particular made of plastic material, wherein the frequency is varied within a predetermined range of frequencies to detect the geometrical configuration of the vibration, followed by selecting the frequency exhibiting the best possible vibratory configuration and defining the operating frequency to which the system will be adjusted.
