A macro-micro coupling model of microstructure dynamic evolution for circular shaped
oscillating laser welding of Inconel 718 superalloy is developed in this paper to investigate …

New generation of multi-core fiber laser sources provide in-source dynamic beam sha**.
Such sources can switch between Gaussian and ring beams, providing new irradiance …

In the laser welding process using a focused Gaussian beam, high thermal gradient and
molten pool instability usually lead to coarse columnar grain, poor surface quality and …

The rotating laser was used in the narrow-gap rotating laser-MIG hybrid welding (NG-
RLMHW) of 5A06 aluminum alloy to suppress porosity and improve joint performance. The …

Active fibre lasers are widely used in the industry for different manufacturing applications
ranging from cutting, to welding and additive manufacturing. The recent introduction of the …

The laser energy distribution on base material (BM) surface plays an important role in the
welding quality. To reduce pore and spatter welding defects during laser welding of …

A dual-mode fiber laser consisting of center and ring beams has attracted significant
attention in the laser welding field owing to its ability to stabilize melt pools and reduce …

Abstract Adjustable-ring-mode (ARM) laser welding displays great potential for improving
the stability of the molten pool and the weld quality of aluminum alloys through the coaxial …
