About Welds with Prepared Parts

Prepared faces are the faces that create the void if required for the basic weld shape to fit in.

These faces are as shown below:

The neutral faces are the faces lying at the top. They are not in contact except in some types of weld creation, for example, for square-butt welds.

These faces are as shown below:

Broad root faces are the faces that create the gap between the two parts.

These faces are as shown below:

To create a weld feature with prepared faces, the face selection sequence matters.

The rules are as follows:

1. The faces are always expected in pairs.
2. The face selection sequence must be maintained constant for each pair. You need to establish a one-as-to-one correspondence between the faces of different sets. In concrete terms, for each set, always select the face from Part A first, and then the face from Part B.
3. If prepared parts have different thicknesses, first select the faces of the thinner part.

Table 1. Examples

Face Selection Sequence S1: support 1 S2: support 2 S3: support 3	Resulting Square-Butt Weld

You can create continuous V-butt welds with prepared parts by selecting adjacent faces of the parts.

Face Selection

1: Three faces of Part1 are selected as subelements to define the first support.

2: The corresponding three faces on Part2 are selected as the subelements of the second support.

When faces are in pairs (that is, there is the same number of subelements inside each support, so that faces have one-to-one correspondence), you can create the weld as follows:
