Final answer:
The second digit in an electrode marked (E71T-5) refers to the welding position. In this case, the '1' indicates that the electrode is suitable for all positions, which means it can be used in flat, horizontal, vertical, and overhead welding positions.
Step-by-step explanation:
In the electrode designation system for FCAW, the second digit in an electrode marked (E71T-5) refers to the welding position. Welding position refers to the orientation of the welding joint and the direction in which welding is performed. It is important to select an electrode that is suitable for the specific welding position to achieve quality welds. In this The second digit in an electrode marked (E71T-5) refers to the welding position.
In this case, the '1' indicates that the electrode is suitable for all positions, which means it can be used in flat, horizontal, vertical, and overhead welding positions. case, the '1' indicates that the electrode is suitable for all positions, which means it can be used in flat, horizontal, vertical, and overhead welding positions.
