Grey Relational Analyzing the Optional Parameters of Welding Process Using Arc Signal.

Abstract - Many researchers have developed a wide range of mathematical methods for predicting the weld strength by arc signals. However, these mathematical methods are too complex to have good use according to the complexity of welding. This paper addresses grey relational analysis to analyze the arc signals. Results indicate that the pulse voltage is the most important factor to the weld strength, optimal parameters can be found and the experiment also proved the conclusion. It was found that grey relational analysis is a good tool to find the most important factor to the weld strength from the processing parameters, which can instruct the actual production.
