The sequence to reuse on the job
- 01Find the elementary weld symbol
- 02Read the value on its left as size
- 03Read the first value on the right as segment length
- 04Read the value after the dash as pitch

Weld Size, Length and Pitch Reading Drill
Practice welding symbol size, length, and pitch by assigning each number to the job it controls on intermittent-weld callouts.
THIS DRILL IS FOR YOU IFI see the numbers but assign them to the wrong thing.
TRAINING PRINTWeld dimensions
THE DECIDING RULESize sits left of the symbol; length and pitch sit to the right as length-pitch.
WHERE IT PAYS OFFLayout · estimating · inspection
SUCCESS AFTER THIS ROUNDDecode a size–length–pitch callout without swapping values.
WHY THIS MISS MATTERS
A callout reads 1/4 △ 2-4.
The values look simple, but swapping the 2 and 4 changes both the deposited weld length and the spacing rhythm.
Leave with a usable decision
- ✓Locate size, length, and pitch by position
- ✓Read an intermittent-weld pair in order
- ✓Avoid treating pitch as clear spacing
QUICK CLARIFICATIONS
Questions that cause this mistake.
Read these after the drill if the same shortcut keeps appearing.
Where is weld size shown on a welding symbol?+
For these common callouts, weld size appears to the left of the elementary weld symbol.
What does 2-4 mean on an intermittent weld symbol?+
It commonly means 2 units of weld length at a 4-unit pitch, subject to the governing drawing units and standard.
