Stretches a manufacturing part to account for steel shrinkage during welding. Adding shrinkage changes the position of marks and openings on the part because they are stretched along with the part. The part shrinks back to its needed size and shape in the welding process.
For plate parts, you can define shrinkage in one or two directions as scaling shrinkage (defined by the expansion ratio and the expansion direction). For profiles, you can only apply scaling shrinkage to the length.
By default, the software prompts you to identify the edges so that it can determine the shrinkage directions. If you select the shrinkage type by global axis, the software sets the primary and secondary axis based on the plate type:
For deck plates, the primary factor is the X axis and the secondary factory is Y axis.
For transverse plates, the primary factor is the Y axis and the secondary factory is the Z axis.
For longitudinal plates, the primary factor is the X axis and the secondary factory is the Z axis.
A small coordinate system, based on the shrinkage directions with the appropriate values, also displays in the Part Monitor.
For built-up profiles, you can define the shrinkage for the web and flange separately.
