Problems solved by technology
Once the parts that are directly used in the air conditioning system after flame welding produce oxides, it may block the pipeline, which will affect the entire system and cause the failure of the entire air conditioning unit.
However, the cost of pickling treatment is high. In order to reduce the pressure brought by production costs, some enterprises will directly adopt the method of straight row and sneak discharge for subsequent treatment. This treatment method will pollute the environment, destroy the ecological balance, and leave immeasurable infinite future trouble

Embodiment Construction
[0026] Exemplary embodiments, features, and aspects of the present invention will be described in detail below with reference to the accompanying drawings. The same reference numbers in the figures indicate functionally identical or similar elements. While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
[0027] The invention is suitable for the gas welding protection occasions of metal fittings requiring gas protection welding in the refrigeration industry.
[0028] According to the embodiment of the present invention, the present invention uses shielding gas to protect the welding parts of the flame-welded parts, so that the flame-welded parts do not produce oxides so that pickling is no longer used, effectively reducing the cost of the enterprise. Cost and reduction of hazardous chemical hazards enable enterprises to enhance practicability without increasing costs, affecting normal use...

The invention provides a gas welding protection device. The gas welding protection device comprises a welding die and a protection cover. Protective gas enters the welding die from a gas injection port in the welding die so as to enter a welded component needing flame welding. The protective gas is released in the welded component to protect a welding part. Along with constant injection of gas, the gas is released outwards from the interior of the welded component and enters the protection cover, the gas releasing direction is changed through a protection cover ventilation hole, the welded part subjected to flame welding is protected again from the outside, sufficient gas protection is conducted from the interior and the exterior, and the protective gas is sufficiently utilized again. Thegas welding protection device is simple in structure and does not occupy additional space, acid pickling treatment is not used or reduced, the enterprise cost is effectively reduced, toxic and harmfuldangerous chemical danger is reduced, the effects of energy saving, emission reducing and environment protecting are achieved, and the technology requirement of products is not influenced.
Description
technical field [0001] The invention relates to the technical field of welding protection, in particular to a gas welding protection device. Background technique [0002] At present, in the refrigeration industry, for example, the parts used in air-conditioning systems are usually flame-welded, and then used directly or after pickling before production. Once the parts that are directly used in the air conditioning system after flame welding produce oxides, it may block the pipeline, which will affect the entire system and cause the failure of the entire air conditioning unit. However, the cost of pickling treatment is high. In order to reduce the pressure brought by production costs, some enterprises will directly adopt the method of straight row and sneak discharge for subsequent treatment. This treatment method will pollute the environment, destroy the ecological balance, and leave immeasurable infinite future trouble. Therefore, it is desirable to propose a gas shielded...
