AG Mechanics CDE Practice Exam

Which of the following welds is the most difficult to make.

1. horizontal

2. overhead

3. vertical down

4. vertical up

The correct answer is: horizontal

The most difficult weld to make among the options provided is the overhead weld. Welding overhead can be challenging because gravity tends to pull the molten metal down, making it harder to control the weld pool and creating the risk of slag and spatter falling onto the welder. In contrast, horizontal, vertical down, and vertical up welds are generally more manageable as they allow for better control of the welding puddle and produce more consistent results.
