Weld properties

Weld properties

Use the Weld Properties dialog box to view or modify the properties of a weld. The units depend on the settings in File menu > Settings > Options > Units and decimals.

Note:

Some of the properties are only displayed in reports, not in drawings.

Option

Description

Prefix

The weld size prefix. Shown in drawings, but only if the weld size is also defined.

The standard ISO 2553 prefixes are:

  • a - Design throat thickness

  • s - Penetration throat thickness

  • z - Leg length

Note that if the last character of the prefix is s , Tekla Structures creates the solid weld object according to the right-hand image so that a equals weld size.

Size

The size of the weld.

If you enter a zero or negative weld size, Tekla Structures creates the weld, but does not display it in drawings.

Type

See List of weld types.

Angle

The angle of weld preparation, bevels, or groove.

Enter a positive value for bevel and groove welds.

Tekla Structures displays the angle between the weld type symbol and the fill type contour symbol.

Contour

The fill type contour of a weld can be:

  • None

  • Flush

  • Convex

  • Concave

This setting does not affect solid weld objects.

Finish

Tekla Structures displays the finish symbol above the weld type symbol in drawings. The options are:

  • G (Grind)

  • M (Machine)

  • C (Chip)

  • (Flush finished weld)

  • (Smooth blended weld face)

This setting does not affect solid weld objects.

Root face

Root face thickness is the height of the narrowest part inside the root opening.

Root face values do not appear in drawings, but you can use the WELD_ROOT_FACE_THICKNESS template attribute in reports to show the root face dimension in the weld list.

Effective throat

The weld size used in weld strength calculation.

Root opening

The space between the welded parts.

Enter a positive value for square-groove welds.

Edge/Around

Indicates whether only one edge or the entire perimeter of a face should be welded.

Edge :

Around :

Workshop/Site

Indicates where the weld should be made. This setting affects assemblies and drawings.

Workshop :

Site :

Position

Defines the position of a weld relative to the work plane. The type and position of the parts to be welded affect the position of the weld.

The options for weld position are:

  • + x

  • - x

  • + y

  • - y

  • + z

  • - z

In most cases, Tekla Structures creates the weld on the face or side of the part that faces in the selected direction (x, y, or z). Also the following factors may affect the position of the weld:

  • perpendicularity of the part edge towards the selected direction (x, y or z)

  • length of the part edge

  • distance of the part edge in the selected direction (x, y or z)

The following image shows welds in different positions:

Connect part/assembly

See Use welds to create assemblies.

Placement

Defines how the weld is placed in relation to the assembly parts.

The options are:

  • Auto

    The weld placement adapts to the typical situation of the weld type.

    Square-, V-, and U-groove welds are located in the middle of the main and secondary parts. Single-bevel and J-groove welds are located on the secondary part side.

    This is the default option.

  • Main part

    The weld is located fully on the main part side.

    Does not affect V- or U-groove welds.

  • Secondary part

    The weld is located fully on the secondary part side.

    Does not affect V- or U-groove welds.

Preparation

Defines which assembly parts, if any, are automatically prepared for welding.

The options are:

  • None

    Parts are not prepared for welding.

    This is the default option.

  • Auto

    Parts are prepared for welding according to the weld type.

  • Main part

    The main part is prepared for welding.

  • Secondary part

    The secondary part is prepared for welding.

User-defined attributes

See User-defined attributes.

Shape

The shape of the weld can be:

  • (Regular, continuous weld)

  • (Intermittent weld)

  • (Staggered, intermittent weld)

# of incr.

The amount of increments in an intermittent weld.

Only use with the ISO standard.

Length

Defines the length value that is shown in the weld mark.

For intermittent welds, defines the length of an increment.

Does not affect continuous solid weld objects.

Pitch

If the advanced option XS_​AISC_​WELD_​MARK is set to TRUE , the center-to-center spacing of weld increments in an intermittent weld.

If the advanced option XS_​AISC_​WELD_​MARK is set to FALSE , the space between the weld increments in an intermittent weld.

Tekla Structures uses the character by default to separate weld length and pitch, for example 50–100. To change the separator to @, for example, set the advanced option XS_WELD_LENGTH_CC_SEPARATOR_CHAR to @.

NDT inspection level

Defines the non-destructive testing and inspection level.

Electrode classification

Defines the weld electrode classification.

Electrode strength

Defines the electrode strength.

Electrode coefficient

Defines the electrode strength coefficient.

Welding process type

Defines the process type.

Reference text

Additional information to appear in the weld symbol. For example, information about the weld specification or process.
