What this covers

Sample questions

The arrow of a welding symbol touches the left face of the stem of a T-joint. A fillet weld symbol is drawn above the reference line. Where does the fillet weld go?

  1. On the right side of the stem
  2. On the left side of the stem
  3. On both sides of the stem
  4. Across the top end of the stem
Show the answer

A. On the right side of the stem

Above the reference line means other side. The arrow touches the left face, so the weld goes on the opposite, right-hand side of the stem. Welding where the arrow touches would be correct only if the symbol were below the line.

A welding symbol is drawn with its arrow pointing upward to a joint instead of downward. Which side of the reference line now means arrow side?

  1. The upper side, because the arrow points up
  2. Whichever side is nearer the joint
  3. Neither; the symbol must be redrawn
  4. The lower side, the same as always
Show the answer

D. The lower side, the same as always

Arrow-side information always sits below the reference line no matter which way the arrow runs or which end of the line it leaves from. The convention does not flip when the arrow points up.

When is the tail left off a welding symbol?

  1. When the weld is made on the other side of the joint
  2. When no process, specification or other reference is needed
  3. When the weld is a fillet weld rather than a groove weld
  4. When the weld is to be made in the shop instead of the field
Show the answer

B. When no process, specification or other reference is needed

The tail exists only to carry references such as the welding process, a procedure number or a detail callout. If there is nothing to put in it, it is omitted. It has no connection to weld type, side or location.
