Induction Pre-Heated Linear Friction Welding

Key Engineering Materials, 2018
A two-level factorial design of experiments (DOE) approach is used to study the effect of four factors (average rubbing velocity, weld pressure, burn-off distance, and preheat temperature) on two response variables (weld strength and energy input) for the induction heating and linear friction welding of AISI 1020 steel.

Linear Friction Welding of a Single Crystal Superalloy

Materials Science Forum, 2012
The effect of forging pressure on linear friction welding (LFW) behaviour of a single crystal Ni-based superalloy was investigated. Crystal orientations of the specimens were controlled and results indicated that welding success is dependent on proximity of the oscillation direction to the <011> direction.

Numerical modelling of the linear friction welding process

International Journal of Material Forming, 2010
Linear friction welding (LFW) is a solid-state joining process applied to non-axisymmetric components. LFW involves joining of materials through the relative reciprocating motion of two components under an axial force. In such process the heat source is given by the frictional forces work decaying into heat determining a local softening of the material

Texture Evolution in Linear Friction Welded Ti-6Al-4V

Advanced Materials Research, 2010
The linear friction welding (LFW) behavior of Ti-6Al-4V, a commercial α + β titanium alloy, was investigated using oscillation frequencies ranging from 30-70 Hz and axial pressures from 50-110 MPa. LFW samples were examined using electron backscattered diffraction (EBSD) to relate the texture to the welding parameters and to the estimated strain and ...

Texture development in Ti–6Al–4V linear friction welds

Materials Science and Engineering: A, 2007
Microstructure and microtexture development in as-welded and post weld heat treated (PWHT) lab-scale (LS) and full-scale (FS) Ti-6Al-4V linear friction welds have been characterized using scanning electron microscopy and electron back-scatter diffraction (EBSD).

Mechanical Property and Microstructure of Linear Friction Welded WASPALOY

Metallurgical and Materials Transactions A, 2010
The mechanical properties and microstructural evolution of WASPALOY joined by linear friction welding (LFW) were investigated in this study. In-situ temperature measurements using thermocouple probes indicated exposure of the weld area to a temperature of at least 1400 K (1126 °C).

Linear friction welding of Ti6Al4V: Experiments and modelling

Materials Science and Technology, 2015
Linear friction welding of the Ti6Al4V alloy is studied. A new definition of the energy input rate is proposed, based on an integration over time of the in-plane force and velocity; a strong correlation with the upset rate is then found. The effective friction coefficient is estimated to be 0·5±0·1 for varying frequencies and amplitudes, with only a ...

Linear Friction Welding of a Commercial Aluminum Alloy

Materials Science Forum, 2016
The mechanical properties and microstructure of a solid-phase compound produced by linear friction welding (LFW) of commercial Al-4.4%Cu-0.5%Mg-0.4%Mn-0.5%Ag alloy have been studied. The samples of Al-Cu-Mg-Ag alloy were produced by ingot metallurgy and subjected to thermomechanical treatment to get different initial microstructures.

Finite Element Simulation of Linear Friction Welding

Advanced Materials Research, 2011
The complete process of linear friction welding of titanium alloy TC17 is simulated using the finite element analysis software ANSYS in this paper. A full structural-thermal coupled transient model is also developed. The results of the temperature field and stress field are discussed.
