Development of Offshore Steel for High Heat Input Welding

, 2019
To reduce the construction cost and period of steel structure, high-efficiency welding methods applying high heat input have been widely employed. However, deterioration of the strength and toughness, especially low-temperature impact toughness, due to the coarse grains in the heat-affected zone (HAZ) of weld steels often comes along with high heat ...

Simplified dynamic model for heat input and output of heat storing stoves

Applied Thermal Engineering, 2005
A simplified method to describe the dynamical heat output from heat storing stoves for small houses with a single or several successive firing batches is presented. Both measurements in a stove and theoretical and experimental studies of the combustion of single wood logs can be applied to study the heat input from the batch firing to the furnace walls.

Heat Transfer Studies in Coiled Agitated Vessel with Varying Heat Input

International Journal of Food Engineering, 2011
Heat transfer studies in a coiled agitated vessel with varying heat input is presented using two agitators namely propeller and disk turbine. Heat transfer rate increases with agitator speed for both the agitators for a given heat input. The heat transfer coefficient also increases with heat input for a given agitator speed for turbine agitator for all

Distribution of Residual Stress in Wire-Arc Additively Manufactured Small-Scale Component: Single- versus Multi-Level Heat Input

Journal of manufacturing science and engineering, 2022
Accumulated heat input during layer deposition causes high residual stress in the Wire-Arc Additive Manufacturing (WAAM) components. The developed residual stress results in defects like distortion, delamination, cracks, and low fatigue life.
