The Weld Model Representation Rule node (the WeldModelRepresentationRule sheet in the Piping Specification.xls workbook) specifies rules for displaying welds in the model. It is important that piping designers see field welds in the model to optimize the location of the welds for welding machines, scaffolds, and so forth.

Material Grade (Optional)

Type the material grade code for the weld. Valid codes are listed in the AllCodeLists.xls workbook on the MaterialsGrade sheet in the Codelist Number column.

Nominal Diameter From (Required)

Define the lower bound of the largest nominal piping diameter for which this weld clearance applies.

Nominal Diameter To (Required)

Define the upper bound of the largest nominal piping diameter for which this weld clearance applies.

Nominal Piping Diameter Units (Required)

Specify the units for the Nominal Diameter From and Nominal Diameter To columns. For example, type in for inches or mm for millimeters.

Weld Class (Required)

Type the weld class code. Valid codes are listed in the AllCodeLists.xls workbook on the WeldType sheet in the Codelist Number column.

Weld Radius Increase (Required)

Specify the distance between the outside surface of the pipe and the top of the weld. This distance is shown as Weld Height in the diagram.

Weld Thickness (Required)

Specify the weld thickness.
