BS EN ISO 18166:2026 - TC

This standard BS EN ISO 18166:2026 - TC Tracked Changes. Numerical welding simulation. Execution and documentation is classified in these ICS categories:

• 35.240.50 IT applications in industry
• 25.160.01 Welding, brazing and soldering in general

This document specifies the execution, validation, verification and documentation of a numerical welding simulation within the field of computational welding mechanics (CWM) and performed with a scientific computational tool (SCT). This document is applicable to the thermal and mechanical finite element analysis (FEA) of arc, laser and electron beam welding processes for the purpose of calculating the effects of welding processes, and in particular, residual stresses and distortion, in support of structural integrity assessment.
