Investigation of Weld Joints by Numerical Simulation
Aleš Čeněk s.r.o.
The monograph focuses on the application of numerical experiment in the field of melt welding. Modelling and numerical simulation and finite element method in the ANSYS program were used to investigate the course of thermal cycles, stresses and deformations arising during the melt welding process in the shielding gas atmosphere.
Predictions can be done by both, conventional methods and modern diagnostic methods. One of the latter is the use of computational technology and numerical simulation using FEM. The ANSYS program provides a structural problem solution in the form of the thermal stresses and deformations occurring at the time of welding as well as after cooling the weldment.
Welding technology can utilise a number of programs specialized in welding process, such as SYSWELD, PAM Assembly, Simufact Welding etc.
Development of numerical methods can be used to design computational models. Their implementation into software systems has opened new possibilities also for the field of numerical simulation of technological processes of welding.
