Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ground wire welding, in particular to a welding ground wire device. Background Technique
[0002] A welding ground wire device is a device specifically used in welding operations. Its main function is to ensure the integrity of the current loop during the welding process and provide a safe and reliable electrical connection. Such a device usually includes a ground wire, a ground wire clamp, and possibly a connecting cable.
[0003] Most of the circumferential seams of the large pressure vessel cylinder are welded by an automatic welding machine. The weld formed by automatic welding is good in shape and stable in weld quality. However, there are the following problems when using automatic welding for large pressure vessels: The ground wire of the traditional automatic welding machine is a welding torch wire with insulating rubber. When welding the circumferential seam of the pressure vessel cylinder, the cylinder needs to rotate, and the ground wire rotates with the cylinder and winds around the cylinder. Since each circumferential seam of the cylinder needs to be welded in multiple layers, the cylinder keeps rotating, and the ground wire is continuously wound around the cylinder. This not only requires a very long ground wire, but also the multiple layers of winding of the ground wire naturally form a coil structure. When a large current passes through during welding, a large amount of heat will be generated in the ground wire, causing the rubber-insulated ground wire to be scrapped and posing a danger of electric leakage, forming a safety hazard. Content of the Utility Model
[0004] The purpose of the utility model is to provide a welding ground wire device to solve the problems put forward in the above background technique.

[0008] A clamping mechanism arranged at one end of the insulating sleeve for limiting the insulating sleeve.
