摘要：

The overall aim behind the work presented in this thesis is to gain and apply an understanding of the coupled mechanical and metallurgical effects of TIG welding of nickel-base super alloy (IN718) by using experimentally validated finite element model, which employed for identify the location and size of recrystallized zone (HAZ) and hot cracking susceptible zone in HAZ. To develop an efficient and reliable Finite Element Model of TIG welding moving heat source and proper validation based on the experimental measurements. To experimental validation of thermal cycle predicted by FE model and study the data acquisition (DAQ) process and effectiveness of thermocouple. To analyze the thermal stress distribution pattern, FZ size and HAZ size by using finite element model. To investigate the susceptibility of HAZ hot cracking in INCONEL 718 weldment using FEM solutions. (C) 2020 Elsevier Ltd. All rights reserved.
