摘要
The invention relates to a wet welding electric arc air sac assisting stable experiment device and a using method thereof. The technical problems that in the prior art, when welding is carried out ina deepwater environment, the electric arc air sac volume is small due to large pressure intensity, and the electric arc zone protection effect is poor are solved. The wet welding electric arc air sacassisting stable experiment device comprises a clamping system and an air sac stabilization system, the air sac stabilization system is provided with an air sac protection cover and an air supply system, and the air supply system is fixedly connected with the air sac protection cover in a penetrating manner through an air supplementing pipe; the upper end face of the air sac protection cover is provided with a first through hole and a second through hole, the first through hole is located in the center of the upper end face, a flux-cored wire penetrates the first through hole, and the air supplementing pipe penetrates the second through hole; and the lower end face of the clamping system is fixedly connected with the upper end face of the air sac protection cover to be used for clamping and fixing a welding gun pipe to the air sac protection cover. The wet welding electric arc air sac assisting stable experiment device and the using method are widely applied to the field of underwaterwet process welding.
