Energy-Input-Based Finite Element Process Modelling of Inertia Welding
A coupled thermal and mechanical finite element model has been developed to describe the inertia welding of RR1000 nickel-base superalloy tubes using DEFORM.
The energy input rate is derived from measurements of torque, angular rotation speed and upset taken from actual inertia welding trials. The model predicts the thermal history of the joint as well as the deformation pattern and final residual stresses.
