ESI SysWeld 2010.0 | 727.4 mb
Using the Welding Simulation Solution, you can predict the heat effects  of welding processes, allowing cost-effective distortion engineering,  and weld quality and residual stress control.
About ESI Group Company
ESI is a world leading software editor for the numerical simulation of  prototype and manufacturing process engineering in applied mechanics.  The key to ESI's success is the use of realistic material physics,  providing "as good as real" virtual solutions, in order to replace the  lengthy trial and error processes on real prototypes.
ESI has developed an extensive suite of coherent, industry-oriented  applications to realistically simulate a product’s behavior during  testing and real life use; to refine manufacturing processes for desired  product performance, and to evaluate the effect of the environment in  which the product is deployed.
ESI’s products represent a unique collaborative and open environment for  End-to-End Virtual Prototyping, thus eliminating the need for physical  prototypes during product development.  This solution allows a  productivity gain, innovation acceleration and significantly reduced  costs.
The company employs over 750 high-level specialists worldwide covering more than 30 countries.
As ESI Group development is based on continuous innovation, the company  is qualified as “innovative company” by OSEO, a French innovation  agency.

ESI’s products represent a  unique collaborative and open environment for Simulation-Based Design,  enabling virtual prototypes to be improved in a continuous and  collaborative manner while eliminating the need for physical prototypes  during product development. The company employs over 750 high-level  specialists worldwide covering more than 30 countries. ESI Group is  listed in compartment C of NYSE Euronext Paris
About PAM-Assembly & Weld Planner
In the early design and process evaluation phase, Weld Planner is first  used to quickly evaluate numbers and positions of welds, clamping  conditions, and design. While its dedicated GUI, ease of use and  simulation speed meet the requirements of product and process design,  Weld Planner allows finding the best possible design in the shortest  possible time range.
PAM-ASSEMBLY is then used to validate the preliminary decisions taken.  The complete physics of material is computed in local models, thus  feeding the global model which is used to compute the overall  distortion. Therefore, the computational effort is reduced from months  to minutes, without losing any precision.
Version 2010 of ESI’s Welding Simulation Suite is embedded in a complete  CAE environment, including dedicated meshing and post-processing tools.
