Keyhole induced-pore is one of the biggest challenges in laser welding of aluminum alloys.
A shaped laser controlling strategy, ring-mode laser, has shown the possibility of reducing …

Research has confirmed a positive effect of laser beam shaping on controlling weld profiles
and keyhole stabilisation, with significant reductions of porosity in weldments. However, few …

In autogenous laser butt welding the variability of the joint gap can cause problems in terms
of weld seam quality. A suitable strategy to alleviate this is to dynamically shape the laser …

A major factor slowing down the establishment of additive manufacturing processes as
production processes is insufficient reproducibility and productivity. Therefore, this work …

This paper introduced the use of an adjustable-ring-mode (ARM) laser beam to optimise the
microstructure and mechanical performance of laser welded 6xxx high-strength aluminium …

Spatters are frequently occurred defects in laser welding, which affect the weld aesthetics,
deteriorate the mechanical performances and even lead to the weld joint rejection for …

Laser welding is the industrially accepted method for the joining of Cu hairpin windings in
the production of electric drives. High brilliance laser beams are scanned over the bare ends …

Powder bed fusion experiments were conducted to investigate the microstructure of
Scalmalloy® utilizing standard circular and Adjustable Ring-Mode (ARM) laser beams. The …

Despite the maturity of laser-based powder bed fusion of metals (PBF-LB/M), some barriers
