- •
FEA provides possibility for predicting the thermal distribution for CJ and LTJ modes.
- •
FEA temperature values show reasonable agreement with experimental measurements.
- •
Absence of excessive polymer defects of dissociation and charing in such type of joining.
- •
IR thermography images give false readings and distorted images in LTJ mode.
