The weld symbol distinguishes between the two sides of a joint by using the arrow and the spaces above and below the reference line. The side of the joint to which the arrow points is known (rather prosaically) as the arrow side, and its weld is made according to the instructions given below the reference line.

The vertical line and the slanted line complete the weld symbol. The vertical line is always to the left of the slanted line no matter what. That’s the standard.
What is the purpose of a weld symbol?
Welding symbols, like sign posts are informational directors. They are placed on drawings by welding engineers and their purpose is to relay information to the welder . In many instances the information relayed is very simple. Occasionally it is necessary for the engineer to relay complicated information.
