Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicle assembly equipment, in particular to a wind shielding mechanism for a welding device. Background Art

[0002] RV has both the functions of "house" and "car", but its attribute is still a car. It is a movable type of car with basic facilities necessary for home. RV mainly consists of two parts: the body and the box. Among them, the strength of the box is guaranteed by the aluminum alloy keel, and the aluminum alloy keel needs to be welded before it can be spliced ​​with the insulation material, inner plywood and outer plywood to form the box;

[0003] Aluminum alloy welding refers to the process of welding aluminum alloy materials. Aluminum alloy has high strength and light weight. The main welding processes are manual MIG welding (metal inert gas shielded welding) and automatic MIG welding, which include base material, welding wire, shielding gas, and welding equipment;

[0004] The aluminum alloy keel is mainly composed of horizontal and vertical aluminum alloys. Therefore, when welding the aluminum alloy keel, you only need to use welding equipment to weld the joints between the horizontal aluminum alloy and the vertical aluminum alloy.

[0005] At present, when welding aluminum alloy, it is usually done in a relatively open working space. In a relatively open room, the air circulates faster, and the occasional draft will further aggravate the violent flow of air. The violent flow of air will cause insufficient gas protection, thus generating welding pores during welding.

[0006] At the same time, because the aluminum alloy keel itself has a small welding area, a manual handheld welding head is used to weld the welding joints. However, when the workers are in a welding environment for a long time, it is more harmful to the human body.

[0007] Therefore be necessary to design a kind of automatic electric welding machine with wind shield assembly. Utility Model Content
