Abstract

The invention discloses a rotating arc sensor for shared-welding-pool twin-wire tandem sequence welding. The rotating arc sensor is applied to the fields of welding automation, robot welding and automatic welding seam tracking, and mainly comprises two conducting rods, a driving mechanism, an eccentric adjusting mechanism, a steam chamber component, an upper end cover, a stop block fixing cover, a motor support plate, an middle-cavity shell, a lower-cavity shell and a signal acquisition device. The driving mechanism drives the front conducting rod to rotate in a circular cone mode during operation, the followed conducting rod is fixed and a shared welding pool is formed by the two conducting rods. The signal acquisition device acquires current signals and initial position signals and transmits the signals to a computer, and corresponding welding seam tracking movements are achieved after signal processing. Compared with the prior art, the rotating arc sensor has the outstanding advantages that cladding rate can be increased while the welding seam tracking is realized, so that welding speed is increased, productivity is improved, and a certain benefit is brought to companies.

Description

technical field [0001] The invention relates to the technical field of welding guns, in particular to a welding gun for eutectic pool twin-wire tandem rotary arc welding; it is not only a welding gun with a special structure, but also can be used as a sensor detection device for seam tracking. Background technique [0002] Twin-wire tandem arc MAG / MIG welding is a new type of high-efficiency welding method, which has been widely used in shipbuilding and machinery manufacturing in recent years. Twin-wire tandem arc MAG / MIG welding has a very high welding speed, and manual welding cannot be used. Robots are generally used to program or teach. This method requires a long teaching and preparation process, and it is difficult to overcome errors caused by weld deformation. Therefore, high-speed and accurate seam tracking has become an urgent need for twin-wire tandem arc MAG / MIG welding. During the welding process, real-time detection of welding torch deviation is a prerequis...
