Description

Technical Field

[0001] The utility model relates to the field of steel structure welding equipment, in particular to a windproof device for gas shielded welding. Background Art

[0002] During the construction of steel structure buildings, it is often necessary to weld steel beams. In the process of welding between steel beams, gas shielded welding is often used. Gas shielded welding will spray shielding gas during the welding process. If there is wind in the welding environment, the shielding gas will be blown away, thereby affecting the welding of the steel beams. Therefore, in the welding structure, windproof devices need to be placed to block the wind.

[0003] However, the existing windproof devices are generally only suitable for use on flat ground. When welding steel beams at high places, they cannot be stably placed or connected to the steel beams, which makes it inconvenient to block the wind during the welding process, affecting the welding of the steel beams. At the same time, the existing windproof devices lack an adjustment structure, and the height of the entire windproof device cannot be adjusted as needed, which makes it inconvenient to adjust the windproof device as needed for use in locations with lower environmental heights.
