'5.2.2 Unequal Legs. The size of a fillet weld with unequal legs shall be specified to the let of the
"Weld" symbol.
Weld orientation is not specified by the symbol and shall be shown on the drawing to ensure clarity."
One other note... According to ANSI/AWS A2.4-98,
1. Basic Symbols The entire symbol is known as: 1.3
"Welding" symbols consists of several elements.
Only the reference line and arrow are required elements. Additional elements may be included to convey specific welding information (see Figure 2). Alternatively, welding information may be conveyed by other means such as drawing notes or details, specifications, standards, codes, or other drawings which eliminates the need to include the corresponding elements in the welding symbol. All elements when used shall have specific locations within the welding symbol as shown in Figure 2. Mandatory requirements regarding each element in a welding symbol refer to the location of the element in every welding symbol. And one of the elements used in a welding symbol is called a
"Weld" symbol (the letters "ing" are not used after spelling out the word Weld).
1.1 Weld Symbols. Weld symbols shall be shown in Figure 1. The symbols shall be drawn "on" the reference line (for illustrative purposes shown dashed).
Now, I don't have the latest edition of A2.4 but, it probably has either the same or similar description... Bottom line is this: The weld symbol is basically one of several elements when combined to their proper locations to become the "Welding" symbol, and only the reference line and arrow are required elements in order to show a "Welding" symbol... There's more in 1.4 thru 1.6 but I'm not going to spell it all out because I need to do some other stuff... Some other participants may add to what I wrote which is basically what Al was describing and Lawrence is correct in adding a detail drawing either on the same page or, referring to the detail drawing number in the tail of the welding symbol in order to locate it on another page.

Henry
