other side weld is placed above the reference line, away from the reader.
Welds on both sides of a joint are shown by placing weld symbols on
both sides of the reference line.

Some weld symbols have no arrow or other side significance. However,

supplementary symbols used in conjunction with these weld symbols
may have such significance. For example, welding symbols for
resistance spot and seam welding have no side significance, but GTAW,
EBW, or other spot and seam welds may have arrow and other side.

References: When a specification, process, test, or other references are

needed to clarify a welding symbol, the reference is placed in a tail on the
 welding symbol. The letters complete joint penetration (CJP) may be
used in the tail of the arrow to indicate that a complete joint penetration
groove weld is required, regardless of the type of weld or joint
preparation. The tail may be omitted when no specification, process, or
other reference is required with a welding symbol.

C. Presenting The term weld symbol and welding symbol have different meanings. A After the practicum students are required to clean the
