Title: Automatic guiding of arc welding head - using instantaneous voltage and current measurements during pendulum movement to control central position of arc, longitudinal speed and wire feed
Inventor: BOROWKA JUERGEN DIPL ING
IPC: B23K9/127
Filed: 1991-04-20
Abstract: Automatic guiding of an arc welding head along a weld joint in which the arc is swung in a pendulum-like manner across the general movement direction and the instantaneous electrcial signals for the weld voltage and current are recorded and used to regulate the arc position and movement characteristics. Instantaneous signals are fed to an artifical neuron network (21) whose individual neurons (calculator cells) are trained onto certain welding conditions and signals are given out (AK) corresp. to connection values for such parameters as sideways displacement, joint geometry. These values are fed to a unit (22) which then controls the weld head (6). Welding conditions monitored by the neuron network are joint height, joint opening angle, joint width etc.. The signals from the unit (22) are used to regulate the longitudinal (V) and sideways (S) movements of the head and the wire feed (R). The neuron network consists of several layers (31,32,33) in which the inlet layer (31) has a number of neuron cells (30) corresp. to the difference parameter profiles to be recorded. The outlet layer (33) has a number of cells corresp. to the reference parameters to be controlled. ADVANTAGE - Good welds are produced despite variable weld joint geometry, i.e. the arc is always maintained in the centre of the joint.
