Analysis for Welding Electric Parameters ofStructural Steel Welding Rod

In this paper, the electric parameters of E4303 and E5015 type structural steel welding rod in welding process are randomly checked and measured by means of Hannover analyser invented by University of Hannover, Germany. The probability distribution of these parameters, such as arc voltage, welding current, short-circuiting time, burning time and cycle time etc. are displayed, and their maximum values and mean values are exactly determined. Through analyzing the results, the characteristics of the metal transfer of welding rod can be more specifically understood and the usability of the welding rod can be evaluated.
