Welding thermomechanical simulation workflow
Welding thermomechanical simulation workflow is a workflow resource for modelling, reproducing and analysing thermal and mechanical conditions that occur during welding-related processes. The workflow supports simulation of controlled heating and cooling cycles, thermomechanical loading, deformation behaviour and material response under welding-relevant temperature and strain conditions. The workflow is intended for research and engineering tasks related to weldability assessment, heat-affected zone studies, thermal cycle simulation, phase-transformation-sensitive materials, residual-stress-related analysis, and comparison between experimental thermomechanical tests and computational or analytical models. The resource is linked to Paton Core Facilities for Welding and Materials Testing and may use experimental data from thermomechanical simulation and materials testing equipment such as GLEEBLE-type systems and mechanical testing machines, where available.

Technical notes
The workflow combines experimental thermomechanical testing logic with computational and data-processing steps. A typical workflow may include definition of the welding-related thermal cycle, selection of heating and cooling rates, sample geometry description, temperature-control conditions, mechanical loading scheme, acquisition of force, displacement, strain and temperature data, post-processing of test results and comparison with modelled thermal or mechanical behaviour. Depending on the research task, the workflow may support analysis of thermal cycles, peak temperature, heating and cooling rates, isothermal holding conditions, deformation under controlled temperature, material response during simulated welding, and changes in mechanical behaviour after thermal exposure. The workflow should not be treated as a fully automatic software tool. The exact setup depends on the material, sample geometry, expected welding process, required thermal cycle, available experimental equipment, sensor configuration and modelling assumptions. The scope of simulation, experimental parameters, data format and interpretation level should be agreed before the work starts. Where computational modelling is included, the workflow may use numerical calculations, scripts, tabular processing, curve fitting, thermal-cycle reconstruction, comparison with experimental datasets and preparation of reproducible workflow documentation.
Data outputs
Typical data outputs include thermal-cycle profiles, temperature-time curves, heating and cooling rate data, force-time curves, displacement-time curves, strain-time curves, stress-strain curves at defined temperatures, deformation parameters, sample geometry and test-condition metadata, processed plots, parameter tables, calculation notes and short technical reports. Depending on the agreed workflow, outputs may also include reconstructed welding thermal cycles, comparison between planned and measured temperature profiles, material response under simulated welding conditions, mechanical-property indicators after thermal exposure, and datasets prepared for further modelling or publication. For reproducible use, the output package may include raw and processed measurement files, workflow description, scripts or calculation files, units, instrument settings, sensor-position information, sample identifiers, README documentation and metadata needed for verification, reuse or repository deposition.
