Online monitoring system and method for a short-circuiting gas metal arc welding process

摘要

The present invention generally relates to a useful online monitoring system and method of user thereof for monitoring a welding process to determine weld quality, weld process stability, and weld geometry for each weld formed during a welding process. More particularly, the online monitoring system has a computer having a graphical user interface (GUI); at least one welding machine; a communication interface for interfacing communication between the at least one welding machine and the computer; a data acquisition system for acquiring welding signal data, the data acquisition system having an associated memory means; a quality management database for managing and storing acquired welding signal data; and a statistical signal processing system in communication with the data acquisition system for processing welding signal data stored in the data acquisition system associated memory means, and in further communication with the communication interface for communicating processed welding signal data to the GUI.
