Seam Tracking in Adaptive GMA Fillet Welding

摘要

Seam tracking methods suitable for fillet welding have been studied by evaluating the methods applied to butt welding. Special attention has been paid to the seam tracking in the adaptive fillet welding, for instance, an effort is made to define the common requirements of the sensing system. Three new ideas suggested for the tracking, the ultrasonics, gamma ray scattering and laser methods, as well as the specific features connected to the welding with robots were also discussed.
