Visualisation of alternating shielding gas flow in GTAW [PDF]

open access: yesMaterials & Design, 2016
The alternating shielding gas technique is a method of achieving transient arc characteristics during arc welding; however the complex flow that occurs through its use has not been investigated previously. A schlieren system was used to image density gradients that arise when alternating argon and helium shield gases, under varying flow parameters ...

High‐Throughput Metal 3D Printing Pen Enabled by a Continuous Molten Droplet Transfer

open access: yesAdvanced Science, Volume 10, Issue 6, February 24, 2023., 2023
The arc plasma‐based M3DPen is capable of additively manufacturing line‐shaped metal structures by controlling the volume of molten droplets. Controlling the droplet volume and the solidification volume of the molten metal allows the surface tension to prevent the molten metal from flowing down due to gravity.
