Adaptive Control Method with changing groove width

摘要

In the present invention, the automatic welding tracking control and the adaptive control method for fluctuations in groove width are controlled to perform oscillation operation in the direction of the welding line while the end of the welding torch performs a vibrational motion with a set amplitude and a set vibration frequency, and the arc voltage The end of the welding torch is moved to remain within the set reference range, and the distance between the end of the welding torch and the base material is controlled to be maintained within the set range, and the end of the welding torch is at the end of the amplitude of the oscillation operation. When positioned, the feed rate at the end where the filler material is supplied can be controlled to be less than the set standard feed rate. In addition, the welding control method using the welding automatic control algorithm and the end of the welding torch are controlled to perform oscillation operation in the direction of the welding line while performing a vibration motion with a set amplitude and a set vibration frequency, and the arc voltage is maintained within a set reference range. The end of the welding torch is moved so that the distance between the end of the welding torch and the base material is maintained within a set range, and when the end of the welding torch is located at the end of the amplitude of the oscillation operation, filler material is It is a method related to control, constant current control, sequence control, high pressure generation control, and gas flow control so that the supplied end feed rate can be controlled to be less than the set reference feed rate, and welded to an appropriate position.
