Carbon dioxide protection welding machine capable of preventing wind interference

Abstract

The invention discloses an anti-wind interference carbon dioxide protection welding machine, and belongs to the technical field of welding, according to the scheme, through the arrangement of an outer pipe, an air blower and other devices, a wind wall spraying air outwards can be formed at the welding position, external wind can be resisted to a certain extent, and the situation that the protection effect of carbon dioxide gas is lost due to the influence of the wind is avoided; compared with an existing windproof device, large shielding cannot be caused, the visual field is wider, use is more convenient, the ventilation wall can take away heat at the welding position, the comfort level of operators is improved, when external wind blows to the welding position, the output power of the air blower can be enhanced through the arrangement of the color sensor, the color developing plate and other devices, and the welding effect is improved. The air wall can better resist external air blowing, carbon dioxide is further prevented from being affected by air, and by arranging a projection lamp and other devices, workers can more directly perceive whether the air spraying pipe is blocked by welding slag or not, and the protective net can be cleaned more timely.

Description

technical field [0001] The invention relates to the field of welding technology, and more specifically, relates to a carbon dioxide shielded welding machine that prevents wind interference. Background technique [0002] The full name of carbon dioxide shielded welding is carbon dioxide gas shielded arc welding. Carbon dioxide gas shielded arc welding uses welding wire as the first level, steel bars as the other level, and uses carbon dioxide gas as the arc medium to protect the metal droplets, welding pool and high temperature metal in the welding area. A fusion welding method with simple operation in application, suitable for automatic welding and all-round welding. [0003] Because of its low cost and easy production of carbon dioxide gas, it is widely used in enterprises of all sizes. During welding, carbon dioxide gas is filled in the welding position, which can protect the welding position. [0004] However, this welding method has poor wind resistance, and carbon diox...

Problems solved by technology

[0004] However, this welding method has poor wind resistance, and carbon dioxide is easily affected by the surrounding airflow, which greatly reduces its protective effect. The existing wind resistance solutions include: installing a protective cover at the welding position, but the protective cover is too heavy. It will affect the welding efficiency of the operator, and will cause a certain shielding of the welding place, reducing the accuracy of welding, so further improvement is needed
