基于统计决策的GMAW焊穿缺陷在线检测

On-line detection of burn-through in GMAW based on statistical decision

焊穿是汽车零部件焊接生产的主要缺陷之一。为实现焊接产品质量的“零缺陷”以及生产过程质量监控的目标 ,提出了一种基于最小二乘 (LS)

Burn through is one of the main defects in auto parts welding production.Present a technique based on the Least Square(LS)prediction and statistical decision methods to automatically detect burn through defect in robotized short arc welding.
