General Welding Symbols

AutoCAD Mechanical gives you the ability to create welding symbols that comply with the active drafting standard. The list at the bottom of the page provides a complete list of supported standards.

AutoCAD Mechanical supports the following:

  • Use of object snaps or entering of coordinate values to define the proposed joint conclusively.
  • Ability to specify supplementary symbols and related data, separately for the arrow side and other side.
  • Ability to place the all around symbol and the field weld symbol at the junction of the arrow (leader) and reference line.
  • Ability to stagger intermittent fillet welds (and ANSI edge welds) on both sides.
  • Ability to select between move stagger and mirrored stagger for JIS intermittent fillet welds on both sides.
  • Ability to select a welding process from predefined lists.
  • Ability to store frequently used welding symbols in a welding library and quickly reuse them.
  • Ability to use multiple reference lines to indicate a sequence of operations (ANSI only).
  • Ability to use two or more arrows (leaders) with a single reference line, enabling you to point to locations where identical welds are specified.
  • Ability to exist as a free-standing object or as a symbol attached to an object in the drawing. When you attach a symbol, the symbol moves with the object whenever you move the object.
    NoteIf the arrow (leader) is attached to an object in the drawing and you want to attach it to another object, you must detach it first.

Reuse Welding Symbols from the Symbol Library

You can add any welding symbol you create to a Symbol Library. Thereafter you can insert welding symbols directly from the library, which can save time. The symbol library is stored in the drawing file, against the drafting standard.
