When submitting an alternative welding process for committee consideration, which item is NOT required to be included?

When submitting an alternative welding process for committee consideration, the correct reason for excluding proposed non-essential variables is that the primary focus is typically on the essential variables that directly impact the integrity and performance of the weld. Essential variables are critical parameters that, if changed, could significantly affect the welding process and the quality of the completed weld.

In contrast, non-essential variables might not have a direct bearing on the weld quality or strength, and therefore, their inclusion in the submission is not necessary. The committee is primarily concerned with evaluating the risk factors and ensuring the proposed welding process adheres to safety and quality standards. Hence, while repair procedures and welding inspection methods are crucial for ensuring that the weld meets the appropriate standards and can be properly evaluated, non-essential variables are less critical in this context.

This rationale explains why including proposed non-essential variables is not a requirement for consideration by the committee.
