Answer

1 percent Explanation 1. Understand the context of welding atmosphere In welding, controlling the oxygen level is crucial to prevent oxidation and ensure a strong weld. The maximum allowable oxygen percentage in the welding atmosphere is typically low. 2. Identify standard oxygen levels for welding For most welding processes, especially those involving metals prone to oxidation, the acceptable oxygen level is usually very low, often around 1%. 3. Select the correct option Based on standard practices, the maximum percentage of oxygen generally allowed for an acceptable welding atmosphere is 1 percent.
