Upset or Flash Weld Symbols
Flash or upset weld symbols have no arrow side or other side
significance in themselves, although supplementary symbols used in
conjunction with then may have such significance. The weld symbols for
flash or upset welding must be centered on the reference line.
Dimensions need not be shown on the welding symbol.
