Title:
SIDE POSITIONING METHOD OF DEVICE TO JOINT AND ITS DEVICE
Document Type and Number:
Japanese Patent JPS5973184
Kind Code:
A
Abstract:
The invention relates to a method and apparatus for the lateral positioning of a member relative to a joint formed between two metal surfaces and having discontinuities. Use is made of an eddy current sensor having at least two probes staggered in the direction of the joint. The signals supplied by each probe are processed separately to obtain a signal representing the lateral displacement. By comparing said signal with a given threshold below the amplitude of the signal in the presence of a discontinuity, it is possible to only transmit to a servomotor signals which are below this threshold, which correspond to an effective measurement of the lateral displacement. Application is to automatic welding machines.
