Cavitation erosion improvement following TIG surface-remelting of gray cast iron

Ion Mitelea et al.

Summary: The paper investigates the impact of surface microstructure on cavitation erosion in gray cast iron parts after rapid remelting and solidification. The results show that the surface melting leads to the dissolution of graphite lamella, and the re-solidified microstructure consists of dendrites of transformed austenite embedded in ledeburite.

Modeling and numerical study of keyhole-induced porosity formation in laser beam oscillating welding of 5A06 aluminum alloy

Wenchao Ke et al.

Summary: This paper presents a numerical framework and methods to suppress porosity formation in laser beam oscillating welding. The study found that porosity decreased and was fully inhibited when using an infinity-oscillating path with a frequency of 200 Hz. The developed multi-physics model aids in understanding keyhole-induced porosity formation during laser beam oscillating welding of 5A06 aluminum alloy.

Effect of weld reinforcement on tensile and fatigue properties of 5083 aluminum metal inert gas (MIG) welded joint: Experiments and numerical simulations

Mingyang Ma et al.

Summary: The weld reinforcement has a significant impact on the mechanical properties of MIG welded joints. While increasing the tensile strength of the joint, it has a detrimental effect on fatigue properties by altering the mechanism of fatigue crack initiation and rupture compared to smooth specimens.
