Abstract
Information-measuring system for arc welding and surfacing was developed. The system allows automatic determination of process state zones, i.e. zone of arc striking, arc running, short-circuiting, open-circuit and arc extinction, thus eliminating any subjectivity in zone identification; and provides an extended set of calculated statistical parameters for each of the states. For this purpose, digitizing of welding current and voltage signals, computer processing by algorithms of automatic recognition and clustering of periodic status zones, using empirical rules, analysis of histograms of distribution of current and voltage signals separately, as well as of histograms of their joint distribution, are used. Built information-measuring system for arc welding and surfacing based on ADC E14-440 and notebook allows calculation of 29 statistical parameters, characterizing the process. Information-measuring system performs automatic identification of the state of welding/surfacing process, thus eliminating the human factor influence on the derived estimates of statistical parameters of the process. 11 Ref., 4 Tables, 8 Figures.
