The processes considered include linear friction, inertia, electron beam and manual metal arc welding. It is found that these welding techniques typically produce a triaxial tensile residual stress field in the weld metal which decays rapidly through the heat affected zone to produce balancing ...
Gas tungsten arc weldingTime-of-flight neutron diffractionThe macroscopic stress distribution across a Zircaloy-4 (Zr-4) GTAW weld was measured by time-of-flight neutron diffraction at the SMARTS diffractometer at Los Alamos National Laboratory. Time-of-flight diffraction enabled the measurement of ...

Introduction Residual stress in a steel structure induced by thermal process such as welding is often up to or even over the yield strength at room temperature. Tensile residual stress is a main factor resulting in stress corrosion cracking, fatigue damage and brittle fracture. When the risk for...
In the current work, we consider a constant reference material density at room temperature. For the heat capacity, thermal conductivity, Young’s modulus, yield stress, and thermal expansion coefficient will be either temperature- or phase-depended as discussed later in Sect.3and given in Table2...

In the analysed specimens, maximum tensile residual stress was ranging from 0.43fy to 0.68fy, while compressive residual stress was ranging from 0.09fy to 0.46fy; its value decreased as the width-to-thickness ratio increased. Murugan and Narayanan [22] used contour method and welding simulation ...
