AWS Certified Welding Inspector — FundamentalsWelding SymbolsEasy

A welding inspector is reviewing a blueprint that specifies a single-fillet weld. The welding symbol shows a triangle with the vertical leg on the left side of the hypotenuse, positioned below the reference line. What does this symbol indicate regarding the weld location?

  1. AA fillet weld on the arrow side of the joint.
  2. BA fillet weld that is not specified for either side.
  3. CA fillet weld on both sides of the joint.
  4. DA fillet weld on the other side of the joint.
Show answer & explanation

Correct answer: A. A fillet weld on the arrow side of the joint.

The fillet weld symbol, when placed below the reference line, indicates a weld on the arrow side of the joint. The orientation of the triangle (vertical leg on the left) is the standard representation for a fillet weld symbol.

Why the other options are wrong

  • B. The symbol always specifies a location unless it's a general note.
  • C. Symbols on both sides of the reference line indicate welding on both sides.
  • D. Placing the symbol above the reference line indicates the other side.

Arrow Side Welding Symbol

A weld symbol placed below the reference line indicates that the weld is to be made on the arrow side of the joint.

  • Below reference line = arrow side.
  • Above reference line = other side.
  • Both sides of reference line = both sides.

Memory trick: Arrow Down, Other Up, Both Everywhere
