Argon is not considered toxic at normal atmospheric levels. However, at high concentrations, argon can displace oxygen in the air, leading to asphyxiation. This can occur in confined spaces or poorly ventilated areas where argon gas can accumulate. Therefore, while argon itself is not toxic, it can be dangerous in high concentrations due to its ability to displace oxygen. **

Argon is commonly used as a shielding gas during welding to protect the weld area from atmospheric contamination. It helps to prevent oxidation and nitriding of the molten metal, which can weaken the weld and cause defects. By creating a stable and inert environment around the weld, argon helps to produce high-quality, clean welds with minimal porosity and improved mechanical properties. **
