Weld

Use this data type to input a Weld at a node. Type “w” in the Data column or select “Weld” from the Data types dialog.

The Weld dialog is shown. Four types of welds are available: Butt, Fillet, Concave Fillet, and a Tapered transition. The type of the weld should be selected from the “Type” drop-down combo box.

Butt weld and Tapered transition require the input of weld mismatch. Mismatch is the difference in the mean radii across the weld.

The SIF for a weld is calculated according to the selected piping code (see Section titled “Piping Code Compliance” from the Code Compliance Manual for details) and is incorporated in the stress calculations. If you have an unlisted weld type, you could specify the SIF for it using the User SIF data type.

Any SIF value specified using the “User SIF” Data item will always overwrite any other SIF value calculated/determined at that node using any other method(s).
