The following references show you the
appropriate geometry you need to select to create a given weld type:

propagation and the symmetrical or double weld:

Square Groove
|
|
- The height of both surfaces must be equal and constant.
- The bottom surfaces must be parallel to upper surfaces.
|
|
V Groove
|
|
- The height of both surfaces must be equal and constant.
|
|
Bevel Groove
|
|
- The height of both surfaces must be equal and constant.
|
|
Weld Propagation
|
|
A weld can be propagated on the adjacent and
tangent surfaces. Furthermore, for a symmetrical or double weld, these
surfaces must also respect the symmetrical rules. |
|
Symmetrical Weld
|
|
The selected surfaces for a symmetrical or
double weld must have a constant offset between them, and their orientation
must be opposite. |
