AG Mechanics CDE Practice Exam

When performing a vertical weld, the welder should move the electrode:

1. Downward

2. Horizontally

3. Upward

4. Vertically

The correct answer is: Downward

When performing a vertical weld, the correct way for the welder to move the electrode is downward. This is because moving the electrode downwards allows for proper penetration and fusion of the weld into the base metal. Moving the electrode horizontally or upward can cause insufficient penetration and create weak welds. Moving the electrode vertically would also not be suitable for a vertical weld as it would not facilitate the proper flow of the weld metal into the joint. Therefore, moving the electrode downward is the correct technique for a vertical weld to achieve a strong and effective weld joint.
