In the electrode number, what does the second to last digit indicate about the position?

The second to last digit in the electrode number is significant because it indicates the welding position eligibility. This coding system is part of the American Welding Society (AWS) classification for electrodes, specifically for E6010, E6011, E6013, and other similar types of electrodes. The values of this digit designate the specific welding positions for which the electrode is suitable: flat, horizontal, vertical, or overhead.

Understanding this digit is crucial for welders, as it helps them select the appropriate electrode based on the position in which they will be working. Using the correct electrode according to the specified positions can impact the quality and integrity of the weld, making it essential for achieving a safe and effective weld in structural applications.

The other components of the electrode number provide information on aspects like the type of weld or the diameter of the electrode but do not specifically denote the welding position eligibility.
