Question: When using the GTAW process, what is the primary consequence of touching the tungsten electrode to the molten weld pool?
Answer options:
- A stronger, more alloyed weld is created.
- The tip of the tungsten is automatically sharpened.
- The welder will receive a mild electric shock. ✅ The tungsten and the weld pool become contaminated.
Correct answer: The tungsten and the weld pool become contaminated.
Explanation: Touching the tungsten to the weld pool causes tungsten contamination in the weld, which appears as a defect on an x-ray, and contaminates the electrode, requiring it to be stopped, reground, or replaced.
