Red Seal Welding Practice Exam

Voltage is directly related to the ________ of the weld pool.

1. Size

2. Depth

3. Fluidity

4. Temperature

The correct answer is: Fluidity

Voltage is directly related to the fluidity of the weld pool. This means that as the voltage increases, the weld pool becomes more fluid and easier to manipulate. It is not directly related to the size or depth of the weld pool, as these are determined by other factors such as amperage and welding technique. Additionally, while temperature does play a role in welding, it is not directly related to voltage and can be controlled by adjusting other variables such as travel speed.
