Abstract
Algorithms of a situational type with an adaptive variation of the correction step are suggested. The latter is varied on the basis of logical analysis of the formed situation characterizing current and previous positions of a tool relative to the welded joint under conditions of an incomplete information that comes from the sensing device. Results of computer modelling of the algorithms are given.
Keywords: robotic arc welding, algorithms, correction, path
