There are two other elements that may be seen on the reference line that provide information about the weld. One is a circle around the place where the leader line connects to the reference line and indicates the weld is ?/FONT>ALL AROUND? This means the weld extends all the way around the joint the arrow is pointing at.
KEY POINT: The all around element is only used when it is possible to weld all the way around a single surface. Otherwise more than on symbol is used.
The other element seen on the reference line resembles a flag and is located where the leader line joins the reference line. This element is called a field weld and means the weld will be done in another location. For instance, this weld may be applied at the job site not in the shop. Sometimes clarification will be given in the welding symbol tail or as a specification on the print.
