Fuzzy Penetration Control for TIG Weld Based on Wavelet-Fractal

Abstract:

Image detection was the important step of Welding automation. In view of the welding image feature of strong noise and poor stability, conventional detect method can not get the clear welding process image, so a fuzzy detection algorithm of welding image based on wavelet and fractal denoising was presented. The fuzzy detection algorithm is used to process welding image and extract molten-pools edge; and then fuzzy PID controlling theory are combined to form a whole image processing and closed-loop penetration controlling system. The experimental results indicated that the controlling system has the good anti-interference ability in welding process and therefore ensure the stabilization of welding formation quality.
