ABSTRACT:
This invention relates to automatic welding of confronting edges of two bodies between which is a groove to be filled with a material and, more particularly, to conditioning, processing and use of control signals representative of an integration of the absolute product of the differences between the arc voltage at the sidewall and the centerline arc voltage and the arc current at the sidewall and the centerline current for an integration window near the sidewall for automatic reversal of the traversing welding torch. 3
