摘要

钨极惰性气体(TIG)焊接是不锈钢焊管生产中的主要焊接工艺。根据不锈钢焊管 TIG 焊接过程中焊接熔池图像的形态特征,利用图像矩计算出钨针针尖的准确位置。提取熔池轮廓中的焊缝区域,基于三次B-样条曲线插值方法对轮廓曲线进行插值,利用S-G滤波器的特性,通过对轮廓曲线进行去趋势处理,去除轮廓曲线中的干扰坐标,提取焊缝特征点,实现焊缝的精确识别。实验结果表明,该方法能准确计算焊接过程中的焊接偏差。

Vision-based algorithm for online TIG welding deviation detection of stainless steel welded pipes.

Tungsten inert gas (TIG) welding is the main welding process in the production of stainless steel welded pipe. According to the morphological characteristics of the welding molten pool image during the TIG welding process of stainless steel welded pipes, the exact position of the tungsten needle tip is calculated using image moments. Extract the weld region in the contour of the molten pool, interpolate the contour curve based on the cubic B-spline curve interpolation method, utilize the characteristics of the S-G filter, remove the interference coordinates in the contour curve through the detrending of the contour curve, extract the weld feature points, and realize the accurate identification of weld seams. The experimental results show that the method can accurately calculate the welding deviation in the welding process.
