AG Mechanics CDE Practice Exam

The "1" in E6013 represents what according to the Numerical Coding for Electrodes?

1. Length

2. Metal Type

3. Welding Current

4. Welding Position

The correct answer is: Length

In the numerical coding for electrodes, such as E6013, the "1" represents the tensile strength of the electrode, which is related to its length. The first two digits indicate the tensile strength of the electrode in thousands of pounds per square inch (PSI). In this case, with E6013, the tensile strength is 60,000 PSI. Therefore, the correct answer is A, as the "1" in E6013 corresponds to the tensile strength or length of the electrode.
