The role of high-purity argon as welding gas in industry

Argon is a rare gas widely used in industry. It is very inert in nature and neither burns nor supports combustion. In aircraft manufacturing, shipbuilding, atomic energy industry and machinery industry, when welding special metals, such as aluminum, magnesium, copper and its alloys and stainless steel, argon is often used as a welding shielding gas to prevent the welded parts from being oxidized or nitrided by air. . Can be used to replace air or nitrogen to create an inert atmosphere during aluminum manufacturing; to help remove unwanted soluble gases during degassing; and to remove dissolved hydrogen and other particles from molten aluminum.

Used to displace gas or vapour and prevent oxidation in process flow; used to stir molten steel to maintain constant temperature and uniformity; help remove unwanted soluble gases during degassing; as a carrier gas, argon can be used in layers Analytical methods are used to determine the composition of the sample; argon is also used in the argon-oxygen decarburization process used in stainless steel refining to remove nitric oxide and reduce chromium losses.

Argon is used as an inert shielding gas in welding; to provide oxygen- and nitrogen-free protection in metal and alloy annealing and rolling; and to flush Glory Metals to eliminate porosity in castings.

Argon is used as a shielding gas in the welding process, which can avoid the burning of alloying elements and other welding defects caused by it, so that the metallurgical reaction in the welding process becomes simple and easy to control, so as to ensure the high quality of welding.

When a customer orders an air separation plant with an output of more than 1000 cubic meters, we will recommend the production of a small amount of argon. Argon is a very rare and expensive gas. At the same time, when the output is less than 1000 cubic meters, argon cannot be produced.
