OVERVIEW

WHAT CAN YOU DO WITH IT

If You …

Want to virtually manufacture each welded design before it is fabricated or repaired.

Work with sheet metal, heavy plates, or both.

Work with structural steel, complex materials, or dissimilar metals in the aerospace, energy, nuclear or chemical

industry.

Require that your welded designs meet tolerance requirements, at minimum cost and within minimum time -

without the necessity of incorporating all the details of complex physics.

Need to optimize the distortion of a welding assembly, taking into account all process details.

Need to ensure that the microstructure after welding meets your requirements.

Need to determine residual stresses as a basis for a high cycle low amplitude fatigue analysis, and to discover

problem zones in the design.

Want to understand the stress and fracture mechanics of the cladding, the heat treatment, and the welding process

of large dissimilar metal welded assemblies caused by the fabrication or repair process.

You Can …

With the Welding Simulation Suite from ESI

WORKFLOW

WELD PLAN

At the beginning of Virtual Welding Engineering, there is a Weld Plan. In many cases, with the components, weld

processes, weld passes, clamps and materials involved in a weld design, it is necessary to provide an overview and to

be able to communicate to the team and customers the details of the virtual welding fabrication process. The

Welding Simulation Suite from ESI incorporates highly efficient tools for virtual welding fabrication planning that

allows smart communication and team alignment to the task.

CAD AND FEM MODELLING

A state of the art meshing tool is integrated in Visual Environment, the solution platform of the Welding Simulation

Suite. It includes powerful tools dedicated to weld modeling.

MATERIAL DATA

Material properties are complex, in particular, if thermal and metallurgical properties are involved. The material data

manager based on Microsoft Excel helps you to view, manipulate and generate properties with all the capabilities

offered by Microsoft Excel. Existing databases cover the most frequently used materials in automotive, aerospace,

6 | P a g e


chemical, energy & nuclear and heavy Industries, and can be used as basis for new material databases. All of the

physics of each material is incorporated in the material database – there is no need to deal with material property

details when you set up a simulation.

PROCESS SET UP

State of the art graphical user interfaces dedicated to welding engineering allow you to set up a virtual welding

fabrication process in the shortest time possible, requiring only welding engineering knowledge. No particular

education in simulation engineering is needed to set up and run a welding simulation.

SOLUTION

For fast distortion engineering, the ESI Virtual Performance Solution solver is used – an innovative new tool offering

unmatched Distributed Memory Processing (DMP) performance for large welded assemblies. For all simulations

involving the complexity of the material physics, the SYSWELD solver is used. It is the most precise multi-physics

solver for welding and heat treatment processes in the market. A team of engineers and scientists received the

Kenneth Easterling Award for a perfect correlation between computed and measured residual stresses. Despite all

complexity covered, the numerical details are computed by the software and the solution is completely automated.

Above all, the solver scales well on 16-processor DMP configurations, with a solve-time improvement factor of 8.

Thanks to advanced simulation engineering methods, you are able to solve complex problems. Large pressure vessel

fabrication involving 100reds of m of welds, dissimilar materials and various process steps such as cladding, heat

treatment and welding are solved in a reasonable time frame, without neglecting material physics or fabrication

details. SYSWELD provides access to a new Universe of virtual welding engineering.

VISUALIZATION OF COMPUTED RESULTS

A state of the art post-processing tool is integrated in Visual Environment, the solution platform for the Welding

Simulation Suite. It includes powerful tools dedicated to providing deep insight in welding fabrication effects. Above

all, you have the ability to review several computed results at the same time in multiple windows, synchronized

through fabrication process, and to directly compare variants, displaying not only the variants, but also the

differences between the variants, no matter which result quantity is concerned.

WELDWARE

WeldWare is a modular welding advisory system, which provides the calculation of thermal transients during

welding.

12 | P a g e


With Weldware you can generate and validate the process parameters you need to perform distortion engineering,

weld quality and residual stress analyses for complex structures.

WeldWare allows you to;

Calculate schematic welding – TTT diagrams according to the chemical composition

Calculate microstructure in the heat affected zone, depending on chemical composition and cooling time

Calculate hardness, yield strength, tensile strength, elongation, reduction of area and impact values

depending on chemical composition and cooling time

Consider scatter of charges during the determination of mechanical properties or cooling times

Calculate the true material composition in multi-pass welds, pass by pass, depending on base and wire

materials, and calculate the properties of the material mix

Determine the necessary heat input and pre-heat temperature. This works well for aluminum, titanium,

nickel and (high) alloyed steels

Calculate the cooling time depending on the welding process, welding parameters, pre-heating temperature,

joint type and material thickness

Once the process parameters and properties are validated, the generated data serves as basis for simulations on

complex structures. The following tools help to complete the information needed for transient welding simulations.

STRAIN HARDENING CALIBRATION TOOL

The strain hardening tool helps to generate engineering data, depending on material temperature and phases. Data

for austenite, depending on the carbon content, is built in.

13 | P a g e


PHASE TRANSFORMATION CALIBRATION TOOL

The phase transformation tool helps to calibrate iso-thermal and continuous phase transformations. It makes use of

the SYSWELD solver to compute the required data – automatically. You only need to enter the engineering data.

14 | P a g e


The results, for example a CCT diagram - can be displayed as follows.

MATERIAL DATA MANAGER

15 | P a g e


The material data manager allows users to create a material database for SYSWELD. You only deal with data in

Microsoft Excel. The thermo-physical properties of all common steel classes are built in. The result is a database in

SYSWELD format that includes all data necessary to perform transient analyses.

NEW GRAPHIC USER ENVIRONMENT TO SET UP AND RUN WELDING SIMULATIONS

VISUAL-WELD has been designed with the objective to give you easy access to more than 100 man-years of experience

in welding simulation. Running the SYSWELD solver, VISUAL-WELD offers the best possible combination of user-

friendliness and result quality.

ENGINEERING GUIDE

SYSWELD includes an Engineering Guide that covers decades of experience. This is not to be confused with the usual

Users Guide. Rather than covering the usage of the software, it mainly deals with the translation of real cases into a

simulation model. It covers and explains the major simulation engineering knowledge as well as the pitfalls related to

The Finite Element method application

The simulation engineering ground

The Engineering Guide shows the most effective, and thus cost effective, ways to solve Industrial problems. The

arrangement of the chapters proceeds in the sequence of a typical study. The Engineering Guide is done in a way

that it can be easily read and understood. A prerequisite is a standard engineering education.
