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

A novel adjustable-ring mode laser (ARM) welding of SUS304L stainless steel sheet was
investigated in this work. The ARM laser consists of two parts: ring laser beam as outer part; …

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 …

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 …

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 …

As a combination of the annular laser beam and gaussian laser beam, adjustable ring mode
(ARM) laser is a promising technology for stabilizing laser-based welding process. Process …

Solidification cracking is a prevalent defect in welding aluminium alloys which can be
effectively mitigated by employing grain refinement strategies. This paper investigates the …

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