What does the term pitch refer to in welding symbols?

• A. The distance from the center of an increment to the center of the next
• B. The welding bead width
• C. The arc length
• D. The heat input

Answer: (A)

Pitch in welding symbols refers to the spacing pattern of intermittent welds along a joint. It is the distance from the center of one weld increment to the center of the next, defining how far apart the welds are laid out. This controls how the weld metal is distributed and how heat is delivered along the joint. It isn't the width of each weld bead, the arc length, or the total heat input, which are different aspects of the weld geometry and process.
