MODELLING OF PERPENDICULARITY OF CUT IN HIGH POWER CO2 LASER CUTTING OF 5 MM THICK ALUMINIUM ALLOY
Nonconventional Technologies Review, 2016 Beside productivity and costs, the cut quality is the third most important criteria in laser cutting. An important quality indicator of laser cutting is perpendicularity of cut. In this paper, the effects of the laser power, cutting speed and assist gas

Fibre laser piercing of mild steel: the effects of power intensity, gas type and pressure [PDF]
, 2013 Laser piercing is used to generate a starting point for laser cutting. The pierced hole is normally larger than the kerf width, which means that it cannot lie on the cut line.

Advanced Engineering Materials, EarlyView.Microstructural evolution and hardness optimization along the cross‐section of friction stir welded AA6061/AlSi10MgMn joints, for electric vehicle battery housings, were investigated. Postweld aging between 170°C and 220°C enhances hardness uniformity within the nugget zone.

Advanced Engineering Materials, EarlyView.In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Advanced Engineering Materials, EarlyView.This study investigates laser metal deposition of aluminum alloys EN AW‐7075 and EN AW‐5083, using powder blending to compensate zinc and magnesium evaporation. In situ alloying and ex situ alloying with ZnAl12 and AZ91 preserve near‐standard compositions and improve mechanical properties.
