AG Mechanics CDE Practice Exam

When welding, one bead or layer of filler metal is known as a/an:

1. Bead weld

2. Pass

3. Root pass

4. Surface pass

The correct answer is: Bead weld

When welding, one bead or layer of filler metal is known as a "bead weld." This term refers to the deposit of filler material laid down by the welding process in a single pass. It is crucial to understand this terminology in welding to effectively communicate and understand welding instructions and procedures. Options B, C, and D are incorrect: - A "pass" refers to a single progression of welding along a joint or workpiece. - A "root pass" specifically refers to the first pass in a groove weld that touches the root of the joint. - "Surface pass" does not hold a specific welding terminology and is not commonly used in the context of welding practices.
