Research on lightweight solver for welding thermal cycle based on Lagrange-Galerkin finite element method
The welding thermal cycle has many interfering factors,fast changing speed and wide influence range,so it is often necessary to predict and control them immediately to ensure the welding quality.Taking the temperature distribution and change of weld center as the research object,and it was simplified to the transient heat conduction problem of one-dimensional welding heat cycle.Based on Lagrange-Galerkin finite element method,a lightweight welding thermal cycle algorithm was developed to study the immediate changes of the temperature distribution curve and change curve of the weld center at different times.The results show that the calculation time is about 0.41～0.72 s,which meets the requirements of data and lightweight calculation.
