Description

Technical Field

[0001] The utility model relates to the technical field of welding protection, in particular to a welding protection device for a signboard frame. Background Art

[0002] Signage frame welding is an important step in signage production. It is the process of connecting the metal materials that make up the signage frame, such as steel and aluminum, through welding technology. There are various welding methods. Manual arc welding is flexible but requires high welder skills; gas shielded welding is efficient and produces good weld quality; argon arc welding is suitable for thin plates and high-precision welding. Its importance is significant. It provides structural stability for signage, keeps its shape stable in various environments, and is not easily deformed or damaged. At the same time, it has good load-bearing capacity and supports panels and other components. High-quality welding can extend the life of the signage and reduce maintenance costs. When welding, attention should be paid to selecting the right materials, controlling process parameters, and doing post-processing.

[0003] The welding protection device of the sign frame is mainly used to protect the safety of the welder during the welding process of the sign frame. Among them, the welding mask is very important. The welding mask can effectively block the strong arc, spatter and harmful rays generated during welding;

[0004] Traditional protective devices mainly consist of a mask body and a shading lens. During welding, they can block the strong arc light and allow observation through the shading lens on the observation window. However, traditional protective devices cannot quickly replace the observation window. Due to the wide variety of signboards and the different materials used, the arc light generated during welding will also vary accordingly, necessitating the replacement of corresponding shading lenses. Therefore, a signboard frame welding protective device is proposed to solve the above problems. Utility Model Content
