• Welding symbols are built using a formula to
  place the different elements.
• When the symbol refers to only one member, the
  arrow will have a noticeable break and point to
  that member (Detail 1)
• Welding symbols may be combined either by adding
  different elements onto one reference line, or by
  adding more reference lines to the arrow (Details
  2 3).
• When more reference lines are added, the
  operations on the line closest to the arrow are
  performed first, operations farthest from the
  line are performed last (Detail 3).
