THE SIMULATOR For over 15 years, E2G has developed and maintained an advanced computational model for the simulation of HotTap welding. E2G's model uses Finite Element Analysis (FEA) with adaptive meshing to simulate the weld's thermal history. This thermal history is then used to assess the risk of failure due to burn-through and cold cracking, to support the safety of the welder and the integrity of the pipeline.
The E2G HotTap thermal analysis welding model has numerous technical and usability enhancements over historical HotTap welding models, including support for more geometries such as Weldolets and user-defined custom fluid mixtures. The weld heat input energy is also distributed more realistically using methods now widely accepted for other welding simulation applications. Another significant advantage of the E2G HotTap thermal analysis model is that it is deployed through a cloud-based infrastructure with an improved user interface, requiring no installation or maintenance on the user side. Updates and improvements are pushed out immediately to users without a lengthy delay or any IT hassles, always ensuring the most accurate and up-to-date results.

WELDING ANALYSIS FOR THE WEB
• Powerful FEA solver with adaptive meshing to maintain high accuracy• Built-in and customizable fluid mixtures• No limitations on critical hardness (no longer restricted to 350 HV)• Evaluates the effects of preheating• Improved handling of liquid boiling cases, including nucleate, transition
and film boiling• Warns when there is a heightened risk of an unstable decomposition
of the fluid mixture • Realistic welding heat source distribution
• Cloud-based delivery • Access from a desktop, tablet or mobile phone• Predicts ranges of safe welding parameters • Generates heat input versus cooling time curves• Time-dependent visualizations and animations• PDF reports with the ability to save and share cases• Parametric analysis of conditions
The E2G hot tap welding model was verified against the historical Battelle and PRCI v4.2 models for hot tap welding thermal analysis. The predictions of inside surface temperature (for controlling burn-through) and weld cooling rate (for controlling cold cracking) have been validated against experimental data. Comparisons show that the model agrees as well or better in most cases with a more solid technical basis, which extends the range of cases where the results can be relied upon.1
