AWS welds are constructed with the Structure_Weld.xml file located in the [Reference Data Folder]\SharedContent\Drawings\Catalog\Labels\Templates folder. Weld symbols created using this XML are assembled from smaller symbols in the [Reference Data Folder]\SharedContent\DrawingsCatalog\Labels\Templates\WeldSymbols folder and flipped as needed to accommodate the view. These processes are handled internally by the DrawingWeldSymbols content module and the DrawingWeldLeader leader module.

Weld Label Flip Behavior

The weld label flips the view direction based on the local coordinate system. There are five different weld flipping behaviors.

Type 1

The physical connection is the target object, which means the local coordinate system z-vector and the view direction z-vector are parallel. If the boundary is closed, the primary and secondary side has a weld point that the leader terminator end point. If the boundary is open, the primary and secondary weld points are at the same position.

Type 2

The physical connection primary side is in the front, which means the local coordinate system y-vector and the view direction z-vector are parallel. In this case, all 2D graphics are on the primary side. Only left-flip is possible.

Type 3

The physical connection secondary side is in the front, which means the local coordinate system y-vector and the view direction z-vector directions are opposing. In this case, all 2D graphics are displayed on the secondary side. Only left-flip is possible.

Type 4

The physical connection primary and secondary sides are parallel to the view direction, which means the local coordinate system x-vector and view direction z-vector are parallel. In this case, the physical connection is a simple line, and the primary and secondary sides are located at the ends of the simple line.

Type 5

The physical connection is in a looking isometric view. This case is very similar to Type 1.

Additional examples of the weld label flipping behavior

If the flipping type is 1 or 4, the weld label symbols invert across the reference line in the label. See the following graphic for an example.

If the flipping type is 2 or 3, the weld label symbol does not change when it flips sides. See the following graphic for an example.

Weld Label Tolerance Angle for Perpendicular or Collinear Reference Lines

According to AWS standards, arrow lines are not perpendicular to the reference weld reference line. Therefore, a default 5 degree shift is added to automatically placed weld labels.

If you attempt to place a weld label perpendicular or collinear to the reference line, the arrow line is not accepted. You can control this value as an option in the XML file. For more information, see Label Templates Overview.

Examples

If the angle of the arrow line is 87, the angle of the arrow line shifts to the 90 degree tolerance angle, which is 85 degrees. See the graphic below for an example.

If the angle of the arrow line is 3 degrees, the angle of the arrow line shifts to a default 5 degrees. See the graphic below for an example.

There are two unique XML tags in this file that allow you to control the tolerance angle of the arrow line in two different situations. These tags are located under the leaderSettings section of the file.

toleranceAngle

Specifies the tolerance range angle in degrees. If the angle of the arrow line is within the range of this option, the arrow line is shifted by the number of degrees specified. The default setting is 5 degrees.

toleranceAngleForSingleBevelJWeld

Specifies the permissible range of the leader line in degrees. If the arrow line is out of the range, the angle of the leader line must be 90 - the tolerance angle specified. The default setting is 15.

  • This option is only compatible when labeling a single-bevel butt weld, a single-bevel butt weld with a broad root face, or a single-J butt weld.

  • If you delete this tag, the weld is labeled straight on without a jog.

  • If this option is set to 0, the leader line is placed perpendicular to the arrow line.

  • The leaders created by the Structure_Weld.xml label are genuine leader objects that are controlled by delivered leader modules.

  • You can use the ALT key while clicking to manually jog the leader.

Representation Arrow Line Pointing at Prepared Edge Line

Single-bevel butt welds, single-bevel butt welds with broad root faces, and single J butt welds are not labeled with the arrow line pointing at the prepared edge. Instead, they are labeled with the perpendicular arrow line pointing at the vertex of the angle. The position of the arrow line with respect to the weld is generally not significant. In the case of single-bevel butt welds, single-bevel butt welds with broad root faces, and single J butt welds, the arrow line points toward the prepared plate. This option is controlled in the XML file through the toleranceAngleForSingleBevelJWeld tag, which you can delete if you want the arrow line to point directly to the prepared edge.

toleranceAngleForSingleBevelJWeld tag enabled

toleranceAngleForSingleBevelJWeld tag disabled

Example

The angle A, is the permissible range of the leader line. If the arrow line is out of the range, the angle of the leader line is 90 - A. The leader line shifts according to the option.

If the option is set to 0, the angle of the leader line is 90 degrees based on the arrow line.

For more information, see Structure_Weld.

Representation Terminator Movement

The terminator moves if there are better positions on the connection label based on the clear space position of the label. Below is an example of the automatically placed label positioning behavior.

If the label is moved to the other side, the terminator is moved with the label. The red line in the example signifies the physical connection. Also, the label inverts depending on its relation to the physical connection location. See the example below.

If the physical connection is open, meaning it is symbolized as a single line, the position of the terminator is retained.
