摘要
熔化极气体保护焊 (GMAW )广泛地应用于自动焊中 ,其焊接过程在干扰存在的情况下易产生焊接质量问题 ,因此 ,自动焊中焊接质量的在线监测已成为制造业中亟待解决的问题之一。为实现焊接产品质量的“零缺陷”及生产过程质量监测的目标 ,采用电弧传感获取的电信号 ,从单变量统计过程控制的应用结果出发 ,提出了把多变量统计过程控制 (MSPC)应用于GMAW过程的在线质量监测。并在自我开发的一套在线监测系统上 ,通过试验验证了MSPC方法的可行性。
Gas metal arc welding (GMAW) has been widely used in automatic welding, where the quality problem often appears during the disturbance. So the on-line quality automatic monitoring has been required in manufacturing. In order to realize the goal of zero defection and meet the demands of the on-line quality monitoring well, the paper uses the electrical signal of welding process, and puts forward the method of multivariate statistical process control on the basis of analyzing the limitation of statistical process control. At the mean time, the on-line monitoring platform has been developed, where experiments have verified the feasibility.
