Abstract

A kind of seam tracking system for laser-MIG hybrid welding has been designed to overcome the defects of existing laser-MIG hybrid welding equipments. Laser vision technology based on image processing has been studied. Line/arc fitting algorithm was applied to data construction for seam. Simulation tracking of seam was conducted by the helping of interpolation algorithm. Welding experiment was conducted with this new system. The results show that the clear skeleton of structured light can be get by image filtering and image refining. Fitting accuracy of line/arc fitting is within acceptable limit. Tracking accuracy of simulation tracking based on line interpolation and arc interpolation is high. Appearance of welding seam is well.
