Abstract

The invention discloses a local dry automatic welding drainage device, which is mainly composed of a drainage hood frame (1), a flexible welding torch (2) and an underwater welding camera (3), wherein the camera-connected end cover (12) of the drainage hood frame (1) is provided with a lens (121), a sealing ring (122), a intake blowhole (123), a buffering gas chamber (124) and an annular metal screen (125). The camera-connected end cover (12) is connected with the underwater welding camera (3) via a coupling flange (31). A welding torch input port is arranged at a side of the invention, which is fixed with the flexible welding torch (2) via snap ring (131). The bottom of the tube of the drainage hood frame (1) is the external screw thread which is reelingly connected with the internal screw thread of the screwed flange (111). A sealed body (14) is stuck to the tube (11) and the screwed flange (111) via adhesive, and impacts a workpiece (4). The underwater welding camera enables the remote supervision and control of the welding in the drainage hood frame (1). The automatic welding drainage device has an advantage of higher welding quality and efficiency, simple structure, easy use, maintenance and repair.

Description

technical field [0001] The invention relates to welding equipment, in particular to a drainage device capable of realizing underwater partial dry automatic welding. Background technique [0002] At present, there are many kinds of underwater welding methods being applied and researched in the world. The more mature one is arc welding, and the commonly used ones are underwater wet welding, underwater partial dry welding and underwater dry welding. The underwater wet welding equipment is simple, low in cost, flexible in operation and strong in adaptability, but the welding quality is unsatisfactory; the welding quality of the underwater dry welding is relatively ideal, but it needs to design and manufacture complex pressure chambers or working rooms, equipment Complicated and expensive. Underwater partial dry welding combines the advantages of wet and dry underwater welding methods. It is an underwater welding method that takes into account welding quality and operating costs...
