Product Overview:

Fusion welding is a process that joins metals through the melting, or coalescence, of materials. This method is extensively used in the construction of large-scale structures such as ships, offshore platforms, steel bridges, and pressure vessels. In this study, the heat generated by a moving welding arc was simulated using a volumetric heat source, based on the double ellipsoidal distribution from the Goldak model. The heat source was modeled in Abaqus using the DFLUX user subroutine. Both convection and radiation were applied as thermal boundary conditions for the simulation.

Key Topics:

• Establish models to simulate heat flux within the weld.
• Understand the impact of thermal properties on material behavior.
• Analyze temperature distributions effectively to predict performance.
