Abstract

The method with sensing of MIG welding pool surface is studied in this paper.The distributing of arc action spectrum, pool reflecting action spectrum and pool radiating action spectrum are analyzed. The radiation is weaker at interzone 500-700nm. So, the structured light source is confirmed to semiconductor laser at wavelength 650nm. Narrow band filter and neutral density filter are mounted on CCD, they are good for restrained the influence of arc. The pool width is studied on small current by experimented, deforming and distributing of structured light are confirmed. The form and sort of splash are studied, the method of reducing and protecting splash are also studied. Welding current is selected properly to restrained splash. Incident angle of structured light is 30 degree. The MIG pool image is captured by CCD. Deformed structured light fringes are reflected the information of the concave or convex of the pool.
