    There are a lot of processes in the welding industry, in order to streamline the call out of these there are letter designations for them. This designation is a letter callout and it commonly follows the first letter of the process name. For example Flux Cored Arc Welding is FCAW.

    When a process is specified it will be located in the tail of the welding symbol. This can be added to several other components on the welding symbol.

    Method

    The method by which the weld is applied may also be listed in the welding symbol. This will often be seen after a process with a hyphen. There are four different methods of applying a weld and the designation is the first two letters from the first word for the first three. Number Four comes from the first two letters of the hyphenated words. These methods vary depending on process and may not be applicable to all welding processes.

    The above image shows a Gas Tungsten Arc Weld process using a Manual method.

    Also included in the tail could be a reference to a drawing number, a welding procedure (commonly called out as WP,) filler material, or any other pertinent information that may need to be communicated to the welder or fitter.

    Examples of this information:

    Drawing Number 5DWG5

    Welding Procedure 6WP-6
