ESI Group Learning Soluti onsVisual-WELD Hybrid Butt Weld Tutorial 2 August 2010

Description:This tutorial will describe how to setup a model for welding simulation. This

example uses both ARC and Laser Beam welding on a butt joint. It will illustrate how to define

the weld problem and submit the job for results analysis.

Starting the Welding Project

Open Visual-WELD 6.5.

In the main menu, select File >Open.

Select BUTT_HYBRID _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

Input the project details as following:

o *Name: BUTT_HYBRID

o Title: Butt Welding of an Inconel Specimen

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

o General description: Example on butt joint laser hybrid welding

(symmetry condition applied; combined heat source arc

and beam applied)

o Material description: Inconel 718

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 and press OK.

For the Material, choose INCONEL 718 from the pull down menu and clickAdd.

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

Click on the list part of the button and select J01_WIRE.

For the Material, choose INCONEL 718 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 Hybrid.

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.

As a result all the corresponding weld entities are automatically filled in.

Press Next >> or select the Weld Pool tab.

Select Beam from drop down menu as Heat Source:

Input following values for:

o *Velocity: 25.000

o *Start Time: 0.000

o End Time: 2.000 (automatically calculated based on Weld line length)

Input *Estimated values for:

o Top Dia.: 2.000 ( mm units )

o

Bottom Dia.: 1.800 ( mm units )o Penetration: 6.000 ( mm units )

Press Next >> or select the Energy Tab.

Input following values for:

o *Energy/Unit length: 60.000

o *Efficiency: 1.000

Toggle on Start/End Energy Ramp and input the following values in the second figure:

Click on , select J01_PATH again and press OK.

Press Next >> or select the Weld Pool tab and select ARC as the Heat Source:

Input following values in the Weld Pool andEnergy tabs:

Click on the Addbutton to update the Weld Line.

Proceed to Step .

Cooling Condition

Click on thelist part of the button, chooseSOLID_AIR_HEAT_EXCHANGE and press OK.

Choose the *Medium as Free Air Cooling and input 20 as the Ambient Temp.

Click on the Addbutton to update the heat exchange condition.

Proceed to Step .


9/11


Clamping Conditions

Click on the list part of the button, choose CLAMP_03 and press OK.

Choose the Symmetry radio option as the clamp type and click on the Addbutton.

Click on the list part of the button again and select CLAMP_01.

Choose the Rigid radio option as the clamp type.

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

Repeat these steps for:

o CLAMP_02: toggle on Rigid in the Y andZ directions, and press Add.

o CLAMP_04: toggle on Rigid in the Z direction, and press Add.

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

Input *Start time: 0.0 and*End time: 600.0. ClickAdd to create the condition.

Click and select CLAMP_01, CLAMP_02, andCLAMP_03.

Input *Start time: 600.0 and*End time: 601.0.ClickAdd to create the condition.

Click and select CLAMP_01, CLAMP_02, andCLAMP_03.

Input *Start time: 601.0 and*End time: 3600.0.ClickAdd to create the condition.

Proceed to Step .

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 betoggled 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 BUTT_HYBRID.vdb (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.
