The center-to-center distance between intermittent welds is called the ____.

• A. Pitch
• B. Span
• C. Spacing
• D. Gap

Answer: (A)

Pitch is the center-to-center distance between intermittent welds. This measured spacing is the standard way to specify how far apart welds are along a joint, from the center of one weld to the center of the next. It matters because it controls how many welds fit in a given length and how load and heat are distributed across the joint. A larger pitch means fewer welds and more metal between them, which can change strength and fatigue behavior; a smaller pitch means more welds and tighter distribution of stress. The other terms are less precise for this concept. Span typically refers to the distance between supports or the overall length of the weld bead itself, not the center-to-center spacing. Spacing is a general descriptor of distance but isn’t the specific engineering term for the center-to-center measure. Gap describes the clearance between features or the space between edges, not the spacing of weld centers.
