英文摘要	There exists a direct relationship between the weld pool oscillation frequency and volume of weld pool. But the detection of oscillation frequency in continuous condition is difficult. A new laser-vision method was proposed for detecting the weld pool oscillation frequency under the condition of stationary and continuous welding. In order to study the rule of weld pool oscillation frequency from partial penetration to full penetration, several experiments with stationary and continuous condition were conducted and the change mode of frequency was analyzed. The results showed that from partial penetration to full penetration, there was a mutation mode in stationary condition. In continuous condition, the weld pool was elongated and the arc had an asymmetrical position with respect to weld pool center, which resulted in two change mode, mutation mode and continuous mode. This characteristic of frequency can be used in sense and control of weld pool penetration of GTAW. © 2017, Editorial Board of Transactions of the China Welding Institution, Magazine Agency Welding.
