Product Overview:

Understanding and predicting the thermal behavior and residual stress in welding and additive manufacturing is crucial for improving product performance and reducing manufacturing costs. This tutorial introduces a simplified Abaqus model that mimics Wire Arc Additive Manufacturing (WAAM) or a multi-pass welding process, ideal for aerospace, automotive, and marine industries.

The tutorial uses heat transfer modeling, material addition (element birth technique), and a Gaussian heat flux defined through a DFLUX subroutine, all implemented in Abaqus/Standard. The simulation replicates the deposition of a semi-circular bead using a Python script for automation and FORTRAN subroutine for custom heat input.

This short, beginner-friendly video is designed to help engineers simulate thermal effects and build complex thermal-mechanical models for welding and AM.
