Finite Element Analysis of Weld Thermal Cycles Using ANSYS

This book aims at transient analysis of welding thermal cycles using ANSYS explaining basic size of the element, welding speed, distance moved by the arc, and methods of simplification of the complex 3D analysis. Case studies for different welding processes, heat input, arc shape, size of the element, and speed of welding are also provided.

G. Ravichandran has had 37 years of experience with theWelding Research Institute which is affiliated to BHEL, Tiruchirappalli, India, and retired from WRI in 2017. His field of specialization is welding simulation using finite element method, prediction and control of distortion and residual stresses, design of static and fatigue loaded welded structures, experimental stress analysis etc. He obtained his PhD from Indian Institute of Technology, Madras in 1996 for his work on the "Analysis of axis shift distortion and residual stresses during circumferential welding of thin walled pipes". He received the W H Hobart memorial award from American Welding Society in 1997 for his research paper "Prediction of Axis Shift Distortion during Circumferential Welding of Thin Pipes using the Finite Element Method". He was a guest faculty for the National Institute of Technology during the years of service in WRI and handled classes for the post graduate program on welding engineering. After his retirement, he has joined NMAM Institute of Technology, Nitte, Karnataka as Professor Adjunct in Mechanical engineering department.
