“…This study also focused to find out the effect of clamping forces, material thickness and coefficient of friction during heat generation at the weld interface. Sunar et al [11] discussed the temperature and stress analysis of sheet metal during arc welding. In this study, a control volume approach is introduced for the numerical solution of heat transfer equations while finite element method is adopted for stress field predictions.…”

-Ultrasonic welding is a solid-state joining process that produces joints by the application of high frequency vibratory energy in the work pieces held together under pressure without melting. Copper and its alloys are extensively used in electrical and electronic industry because of its excellent electrical and thermal properties. This paper mainly focused on temperature distribution and the influence of process parameters at the joint interface while joining copper sheets using ultrasonic welding process. Experiments are carried out using Cu sheets (0.2 mm and 0.3 mm thickness) and the interface temperature is measured using Data Acquisition (DAQ) System (thermocouple) and thermal imager. Numerical and finite element based model for temperature distribution at the interface are developed and solved the same using Finite Difference Method (FDM) and Finite Element Analysis (FEA). The results obtained from FDM and FEA model shows similar trend with experimental results and are found to be in good agreement.

“…This being the limitation the DC straight polarity was used for the investigation. Fig 2 shows the positions on the plate where the thermocouples were glued to a depth of 1 mm in the holes drilled at the bottom of the plate [13]. The data on the temperature were acquired every second during welding from these 3 locations as well as the room temperature.…”

“…The conduction heating of the solid with constant temperature source at the fixed end is considered to simulate the welding process for 2-D problem reported by Sunar et al [25]. Here, the 3D transient heat conduction equation for a thick rectangular T-joint plate heated at T-joint section is written as:…”

In this paper transient thermo-elastic-plastic problem of a thick rectangular T-joint fillet weld plates is solved numerically in which we need to determine the temperature distribution, thermal deflections and stresses when the boundary conditions are known. At the T-joint section (weld pool area) high constant temperature is considered initially and convection boundary conditions are applied at other three edges as well as top and bottom surface of the plate. T-joint section and vertical plate is fixed (case 1) for plate stability, only T-joint section is fixed (case 2) as a boundary constraint for stress analysis. Numerical technique (Finite element method, Ansys software) is used to obtain the solution of the boundary value problem.
