MSC Simufact Joining Optimizer 2025.2

Simufact Joining Optimizer

Simufact Joining Optimizer is a specialized virtual simulation software designed to predict, analyze, and optimize a wide range of joining processes—including welding, mechanical joining, brazing, and similar methods—before physical production begins. Developed by Simufact (a Hexagon company), this powerful tool focuses on eliminating common joining defects such as distortion and residual stresses, which are primary causes of quality issues, rework, and scrap in manufacturing industries. Version 2025.2 continues Simufact’s mission of making advanced process simulation accessible to engineers without requiring deep CAE expertise. With its intuitive workflow and application-oriented design, Joining Optimizer enables manufacturing engineers to rapidly evaluate process parameters, compare joining sequences, and identify optimal solutions—significantly reducing physical trials, material waste, and production delays while ensuring joint quality and structural integrity.
