The Numerical Simulation and Control of Microstructure in Heat-affected Zone in GMAW
Modern Applied Science, 2009 Summary: The grain size in heat affected zone (HAZ) of welding piece is an important element for evaluating the welding quality. The Monte Carlo (MC) technique, a stochastic simulation method, could be applied to simulate the microstructure in HAZ. A finite element model (FEM) was employed to simulate the GMAW temperature field and the data of the ...

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion
Advanced Engineering Materials, EarlyView.This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

On the Brittleness of Heat-Affected Zone (Report 8)
JOURNAL OF THE JAPAN WELDING SOCIETY, 1956 This experiment was carried out to investigate the influences of pre-stain for the brittle zone of welded part, using both killed and rimmed steel plate. Test plates were pre-strained by tensile plastic deformation ranging from 0 to 10% after full-annealing. Then, single beads were welded.
