What is Weld Metal Solidification Modes Analysis about?
The document discusses how the microstructure within weld grains can vary based on location within the weld and welding parameters. It notes that the solidification mode and dendrite/cell spacing can change from the fusion line to the centerline due to differences in cooling rate. Higher heat input results in lower cooling rates and coarser microstructures. Arc oscillation and pulsation can be used to refine dendrites by increasing cooling rates through disturbances to the weld pool flow.
