Three-Dimensional Temperature Field Calculation
Three-dimensional temperature field calculation is a numerical model for simulating heat distribution and cooling in complex weld geometries. It helps optimize the welding process and avoid defects.
Physico-chemical mechanism of action
The calculation considers heat conduction, radiation, and convection in a three-dimensional space. It models how temperature changes over time and location in the weld geometry.
Metallurgical relevance & risks during welding
Incorrect cooling can lead to hardening phenomena like martensite formation or grain coarsening. The calculation helps predict and control these processes.
Workshop practice & instructions
Use CAD software to model the weld geometry. Input the correct material data and define the heat source (weld tip). Let the program calculate the temperature distribution over a certain time. Use the results to adjust the cooling strategy, e.g., by changing welding speed or shielding gas.
