Why Does 304 Stainless Steel Pipe Welding Need To Use Argon Gas Protection

The main reasons why argon gas protection is needed when welding 304 stainless steel pipes are as follows:

1. Prevent oxidation: Argon is an inert gas and does not easily react chemically with other substances. During the welding process, high temperatures will cause oxidation reactions between iron, chromium, nickel, and other elements in stainless steel and oxygen in the air, leading to rust. Using argon shielding prevents oxygen from coming into contact with the welding area, thus preventing oxidation.

2. Improve welding quality: Argon gas protection can ensure that the welding area is not oxidized at high temperatures, thereby improving welding quality. In addition, argon can help the molten metal fuse together better, reducing welding defects.

3. Protect the safety of welders: Argon is a colorless, odorless, non-toxic gas and harmless to the human body. The use of argon gas protection during the welding process can prevent the generation of harmful gases and smoke and protect the safety and health of welders.

In short, the use of argon gas protection when welding 304 stainless steel pipes can prevent oxidation, improve the welding quality, and protect the safety of the welder.
