Rolls Royce

Industry: Marine & Offshore

Since 1849, Rolls-Royce has remained committed to the marine market and maintaining its world leading position in the design, development, supply, and support of products and systems for commercial and naval customers.

The Challenge

Engineers are looking to better quantify the complex effects of different welding techniques on the materials being fused, ultimately incorporating these techniques in the training of human welders as well as robotic ones.

Dassault Systèmes Response

SIMULIA’s Abaqus Welding Interface (AWI), an extension of Abaqus/CAE, streamlines the generation of two-dimensional welding simulations by providing a graphical user interface for defining all aspects of the weld model. This has allowed Rolls-Royce to carry out further analysis of both thermal and structural models directly within the Abaqus unified finite element analysis (FEA) environment.


Used in combination with Abaqus/CAE, the AWI reduces data translation issues, training time, and expense by allowing engineers to carry out further analysis of these models directly within the Abaqus FEA environment. Automation of surface definitions for heat transfer coefficients speeds the process of weld-buildup modeling.
