Transverse welds data

Transverse welds locally weaken a member and can thus have a large impact on the Combined Section/Stability Check. They can be defined as additional data.

Name

Specifies the name of the data.

HAZ (Heat Affected Zone) data

Weld method

MIG

MIG – method (MIG : Metal Inert Gas welding)

TIG

TIG – method (TIG : Tungsten Inert Gas welding)

Weld material

The user can select the appropriate welding material.

Temperature

Default: 60°C.

Input between 60 – 120 °C.

Note: The unit used in the dialogue depends on user-made settings in Setup > Units.

More information can be found in EN 1999-1-1:2007 article 6.1.6.3.

Note: The definition of the Number of heat paths is not required here. Heat paths are specifically used for fillet welds, i.e. welds between for example two plates with an angle of 90° between each other. However Transverse welds are by definition always butt welds, i.e. welds between for example two plates with an angle of 0° between each other.

More information can be found in EN 1999-1-1:2007 article 6.1.6.3.

Geometry

This group of parameters specifies the position(s) of transverse weld(s) on a 1D member.

Coord. definition

The position can be input in absolute or relative coordinates.

Position x

Defines the position of the weld.

If more than one weld is being used, this value specifies the position of the first weld.

Origin

Tell whether the distance is measured from the beginning or the end of the beam.

Repeat (n)

Defines the number of welds.

This number includes the weld at the beginning and at the end of the defined interval. If the "on begin" weld or the "on end" weld is not included, the actual number of defined welds is lower (by one or two) than the value defined here.

Regularly

If ON, the welds are distributed regularly over the length of the beam.

If NOT, the following parameter (Delta x) specifies the distance between the adjacent welds.

Delta x

This value specifies the distance between the adjacent welds.

On begin

If ON, the first weld is defined.

If OFF, the first weld is not included.

On end

If ON, the last weld is defined.

If OFF, the last weld is not included.
The procedure to adjust the transverse welds data

  1. Open the Transverse welds input dialog:

    1. either using the Input panel function Aluminium additional data > Transverse welds,

    2. or using process toolbar function Aluminium > Transverse welds.

  2. Type required values and select appropriate options.

  3. Confirm with [OK]

  4. Select the member where the data are to be defined.

  5. End the function.

HAZ zones are taken into account for the scaffolding aluminium check. The value for the yield strength fy is taken as (i) f0 in case the section is not located in a HAZ zone and (ii) f0,HAZ otherwise.

The transverse weld is considered as a weld across the cross-section, i.e. the entire section is subjected to the influence of the weld. This is in conformity with EN 1999-1-1 article 6.3.3.3 (5).
