What pipes need argon electric welding
Introduction: Argon welding technology is a commonly used welding method, which is mostly used for the welding of stainless steel, aluminum alloy and other metal materials.
It is characterized by the use of argon gas as a shielding gas during the welding process, which can effectively prevent oxygen and water vapor from entering the welding area, thus the quality of the weld.
In industrial production, there are many different types of pipes that need to be welded, but not all pipes need to be welded with argon.
So, what kind of pipes need argon-electric welding?
This article will look at the aspects of pipeline materials, pipeline environment, and welding requirements.
1. Pipeline materials.
Argon welding is mainly suitable for the welding of stainless steel and aluminum alloy pipes.
Stainless steel pipes are commonly used in industries such as food, pharmaceutical, and chemical industries for corrosion resistance and oxidation resistance.
Aluminum alloy pipes are commonly used in aerospace, automobile manufacturing and construction, etc., with light weight, high strength and good thermal conductivity.
These two pipe materials are prone to oxidation and embrittlement during the welding process, so it is necessary to use argon as a shielding gas to avoid the intrusion of oxygen and the quality of the weld.
Second, the pipeline environment.
Argon welding is suitable for pipe welding in some special environments.
For example, pipe welding needs to be carried out in a high or low temperature environment, and the protective ability of argon can effectively prevent the invasion of oxygen and water vapor around the weld, and the welding quality.
In addition, some pipe welding needs to be carried out in a confined environment, and the inert properties of argon can avoid oxidation and corrosion inside the pipeline, prolonging the service life of the pipeline.
3. Welding requirements.
Argon joint welding is suitable for some pipelines with high requirements for welding quality.
For example, pipe welding needs to have good sealing properties to prevent leakage of liquids or gases.
The protective ability of argon can effectively prevent the intrusion of oxygen and water vapor around the weld, thereby improving the sealing performance of the weld.
In addition, some pipe welds need to have good corrosion resistance to prevent corrosion and oxidation inside the pipe.
The inert properties of argon can avoid oxidation and corrosion inside the pipeline, prolonging the service life of the pipeline.
Conclusion: In industrial production, argon welding is a commonly used welding method, which is suitable for the welding of stainless steel and aluminum alloy pipes.
It can effectively prevent oxygen and water vapor from entering the welding area, the quality of the weld.
However, not all pipelines need to use argon electric joint welding, only if a shielding gas is required in terms of pipeline material, pipeline environment and welding requirements.
