Starting the Welding Project

Open Visual-WELD 6.5.

In the main menu, select File >Open.

Select T_MULTI_DATA30.ASC and press Open.

Welding Advisor

In the main menu, select Welding >Welding Advisor.

As a result the Welding Advisor is activatedwith Step 1 as Project Description

Project Definition

In the main menu, select Welding >Welding Advisor.

As a result the Welding Advisor is activatedwith Step 1 as Project Description

Input the project details as following:

o *Name: T_MULTI

o Title: 3 Pass Welding of a T-Joint

o *Working directory: Browse and select (Create a new folder if necessary)

o General description: Example on multi-pass arc welding of a T-joint

(preheating step applied before welding)

o Material description: S355 structural steel

Once the mandatory * fields are filled, the next available step(s), in orange, are enabled

to move further. Active steps are shown in blue and completed steps are shown in green.

Click on the Step 2 button or use the Next Arrow to proceed to next step.

Setting the Global Parameter

By default, Welding Advisor automatically identifies the Computation Option needed

based on the Mesh model and sets it. However the user can change and set the required

option accordingly. The Computation Option used here will be Solid.

Proceed to Step .

Component Properties

Click on the list part of the button to post a list of components.

Highlight COMPONENT_01 andCOMPONENT_02 and press OK.

For the Material, choose S355J2G3 from the pull down menu and clickAdd to assign.

Now choose Joints with Filler radio to assign materials to filler materials.

Click on the list part of the button to post a list of joints. Select allfour _WIRE collectors and press OK.

For the Material, choose S355J2G3 from the pull down menu.

Click on Add to complete the material assignment for the Joints.

Proceed to Step .

Welding Process

Choose *Process type as GeneralArc.

Set the Energy / unit Length of Weld: units as J/mm andVelocity: units as mm/sec.

Click on to post a list of collectors. Select J01_PATH and press OK.

All corresponding entities are automatically filled based on their naming convention

Press Next >> or select the Weld Pool tab.

Select ARC from drop down menu as Heat Source:

Input following values for:

o *Velocity: 25.000

o *Start Time: 0.000

o End Time: 8.000 (automatically calculated based on Weld line length)

Input *Estimated values for:

o Length: 10000.000 ( mm units )

o Width: 100.000 ( mm units )

o Penetration: 100.000 ( mm units )

Clamping Conditions

Click on the list part of the button, choose CLAMP_01 and press OK.

Choose the Rigid radio option as the clamp type.

Toggle on Z underRigid in Direction: and click on the Addbutton.

Click on the list part of the button again and select CLAMP_02.

Choose the Rigid radio option as the clamp type.

Toggle on X and toggle offZ underRigid in Direction: and click on the Addbutton.

Repeat these steps for:

o CLAMP_03: toggle on Rigid andY (toggle offX), and press Add.

o CLAMP_04: toggle on Unclamped and press Add.

Once all the clamps are defined, click on the list part of the button,highlight CLAMP_01, CLAMP_02 andCLAMP_03 and press OK.

Keep the default Name: as it is

Input *Start time: as 0.0

Input *End time: as 600.0

Click on the Addbutton to update the Clamping Conditions.

Loads and Deformations

The present problem doesnt involve any loading conditions.

Proceed to Step .

Solution Parameters By default both of the Analysis types are toggled on, but the Mechanical analysis can be

toggled off if it is not needed. In this example, both Thermo-Metallurgical and

Mechanical analyses will be done.

Input *Initial Temperature: as 20.

Click on Advanced arrows to view more options. These will be left at their defaultsettings for this example.

Click on Generate Input Data to export all the project files in the project directory.

This might take a few moments, so check for messages in the console.

Once Generate Input Data is clicked, a *.vdb file is generated. This file contains all theinformation related to project and should be used for any modification related to project.

It is also used as a source file for Solver Manager to solve the project.

Job Submission

Go to the main menu and select Welding > Solution Manager.

Select a project file. This should be T_MULTI.vdb (the same name used in Step 1).

Check all boxes under Heat Transfer and Mechanical and press Compute.

Note: Depending on the system capabilities the solution may take some time to get all theresults.

Cells will turn Green when all the results for that process are computed. Blue indicates a

running job. Any errors are shown in Orange. Use the button to view the log files.

Press Kill Process to end the processing of results at any time.
