2. Weld Symbols A basic welding symbol...
...has a reference line, a leader line, an arrow, an optional tail, and welding information.
reference line - the starting place for the welding symbol. The specifications for how the weld is to be made will be based on the positioning of the other components compared to the reference line.
leader line - takes us to the arrow and can have a special use which will be discussed later.
arrow - points to the joint where the weld should be made.
tail - the tail is optional and is where you can place information that has no designated place on the welding symbol.
