Abstract

1. A method for automatically following a welding seam (4), of the kind in which a possible shift between the said seam (4) and a means for guiding a welding torch carriage (10) is compensated by a corrective transverse displacement of a torch carriage, according to which the corrective displacement is assured within a range of adjustment authorised by a control system positively coupled with mechanical probing of the said seam by means of a feeler probe (34), characterised in that this control operation is assured by periodic performance of transverse advances of a retractable seam feeler probe, which is normally in the retracted position spaced apart from the said seam, the said control action being rendered inoperative in all cases in which the information provided by such a probing operation does not lie within the said authorised range of adjustment, thus manifesting the presence of a welding spot (5) produced prior to the welding operation as such, and in that the said probing operation is resumed immediately until information is obtained which lies within the said authorised range of adjustment.
