FOUNDATION · 4–6 MIN · 5 DECISIONS · NO COUNTDOWNArrow Side vs Other Side Welding Symbol Drill
Stop using arrow direction as a shortcut. Read symbol placement above or below the reference line and name the applicable side with confidence.
THIS DRILL IS FOR YOU IFI keep confusing arrow direction with weld side.
TRAINING PRINTSide significance
Call the correct side before reading any dimensions.THE DECIDING RULEBelow the reference line means arrow side; above means other side in these AWS-style examples.
WHERE IT PAYS OFFFit-up · fabrication · inspection
SUCCESS AFTER THIS ROUNDCall the correct side before reading any dimensions.
WHY THIS MISS MATTERSThe arrow points down-left. The symbol sits above the line.
A fabricator reads the arrow direction and prepares the near side. The callout actually places the weld symbol on the other side.
READ IN THIS ORDERThe sequence to reuse on the job
- 01Trace the arrow tip to the joint
- 02Ignore the arrow's visual direction
- 03Use the symbol's position above or below the line
- 04Say arrow side, other side, or both before reading values
WHAT YOU SHOULD BE ABLE TO DOLeave with a usable decision
- ✓Separate arrow direction from side significance
- ✓Identify arrow-side and other-side placement
- ✓Explain why a wrong-side answer fails

Read these after the drill if the same shortcut keeps appearing.
Does the direction of the arrow determine the weld side?+
No. The arrow identifies the joint; symbol placement above or below the reference line controls side significance in these AWS-style examples.
What does a symbol on both sides of the reference line mean?+
It calls for the indicated weld on both the arrow side and the other side of the joint.
