If the length and pitch for an intermittent weld are 4-10, what is the spacing between successive welds?

If the length and pitch for an intermittent weld are 4-10, what is the spacing between successive welds?

• A. 8 inches
• B. 6 inches
• C. 4 inches
• D. 10 inches

Answer: (B)

Intermittent welds use two measurements: how long each weld is (length) and how far apart the starts of successive welds are (pitch). The spacing between welds is the gap between the end of one weld and the start of the next, which equals pitch minus length. With a weld length of 4 inches and a pitch of 10 inches, the gap is 10 − 4 = 6 inches. So the spacing between successive welds is 6 inches. (If you were thinking center-to-center spacing, that would be the pitch itself, but the requested spacing is the gap.)
