According to the wire and
nozzle movement track in groove, the movement parameters of wire were memorized and
recalled for the following top welds by using a single chip computer. In this paper, it was also
discussed that the design problems of correcting deviation of wire movement track in narrow
gap submerged arc welding process must be noticed in order to obtain the sound welding
result.
