Project: HiCAD Sheet Metal

Welded Corner

Sheet Metal > Further functions > Extras > Welded corner

Use the Welded corner function to create a welded corner between two flanges of a Sheet Metal part. The flanges can have different lengths and bend angles. For such cases you can choose between different types of transitions.

When you activate the function the following dialogue window will be displayed:

Proceed as follows:

1. Identify the two sheets, each at one of the two longitudinal edges of the front side.

If you want to identify a different front side, click the icon in the Edge area of the dialogue for identification.

If you click on the icon you can take the standard for the semi-finished product from the Catalogue Editor. The selection of the semi-finished product influences the sheet thickness, the material and the article number. A double-click on the Welded corner entry in the Feature log allows you to activate or deactivate the semi-finished product later.

2. Enter the Sheet thickness for the welded corner.
3. Enter the Angle for the welded corner.

(1) 60° angle of welded corner
(2) 45° angle of welded corner

The welded corner will also be inserted in cases where the affected flanges of the original sheet collide in developed state. In such cases an error message will be issued:

4. Choose the Mode of the bend zone.

Composite sheets (e.g. ALUCOBOND® panels) are deformed by using milling edges. The resulting bend zones differ geometrically from the cylindrical bend zones. Therefore, HiCAD offers the option to choose between bend zones and milling edge zones.

The following modes are available:

Use the Groove form option to choose the matching tool for the milling edges from the catalogue Factory standards > Composite panels, groove form.

5. Enter a Bend radius for the bend zone.
6. Enter the Clearance for the weld material.
7. Choose an Allowance method.

To preserve the development of the welded corner, HiCAD offers a development according to different calculation methods ("Allowance methods") that consider the material-dependent length changes of the workpiece that occur during the bending process. In HiCAD, the practice-oriented allowance methods are available for the selection.

Each allowance method is represented by a corresponding system file. These files have been prepared according to an example; in practice, however, it can be assumed that users will want to save one or several, user-defined files. Before applying the welded corner you can choose a system file here.

8. If the flanges have different lengths, specify the handling of the bend zones.

The following options are available for a processing of flanges with different lengths or angles:

9. Confirm your entries with OK.

Once you have entered all required data, you can create the welded corner. Click Apply to insert the welded corner, while the dialogue window remains open, allowing you to make further changes if desired. Click OK to insert the welded corner and close the dialogue window. Click Cancel to close the dialogue window and discard all inputs, without creating the welded corner. Click Preview to update the welded corner after changes in the dialogue window.

Please note:

Incorrect inputs will be indicated by the symbol. Move the cursor over the symbol to display the error message.

If the function cannot be executed with the entered data, the symbol will be displayed next to the OK button. Move the cursor over the symbol to display the error message.
