Abstract

The invention provides a surrounding type welding device for water conservancy pipeline machining and a welding process of the surrounding type welding device, and relates to the technical field of welding devices. The problems that although an existing device can achieve annular welding, the cooling effect at a welding seam position is slow, and the welding quality is difficult to observe due to large smoke in the welding process are solved. According tp the surrounding type welding device for water conservancy pipeline machining and the welding process of the surrounding type welding device, the device comprises a base, the base is placed on the ground, a rotating shaft is rotatably connected to a seat body, three blades are installed on the rotating shaft, and the blades are aligned to butt joint positions of two pipes; a gear A is mounted on the rotating shaft; and a gear B is installed on the rotating shaft and meshes with the gear A, and the gear ratio of the gear B to the gear A is 5: 1, so that cooling and smoke blowing can be automatically achieved in the annular welding process.

Description

technical field [0001] The invention belongs to the technical field of welding devices, and more specifically relates to an encircling welding device for processing water conservancy pipelines and a welding process thereof. Background technique [0002] Water conservancy pipelines need to be welded when they are connected to each other, so as to prevent leakage caused by water entering the joint of the two pipelines. When welding two pipelines, a welding device is required. [0003] For example, the application number: CN201410349990.X, the present invention provides a multi-stage sliding type wrap-around welding device and a welding method using the welding device, which includes: a reversing mechanism, which is deployed or retracted in multiple stages along the outer peripheral surface of the tubular object, In order to surround the outer peripheral surface of the welding object, welding can be smoothly realized while unfolding or retracting in a multi-stage sliding manner...
