Abstract

Welding temperature is the main factor that influences welding quality in high frequency induction welding process of composite aluminum alloy thin-walled tube. The finite element analysis software ANSYS is used to simulate temperature field. One complete penetration of thin-walled tube and boundary conditions of thermal calculation are taken into account. Then a linear thermal model is used to load and calculate to draw temperature distribution and thermal cycle curves of welding process. Research results provide corresponding theoretical basis for further analysis of welding stress and strain.
