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

Investigation of Magnesium and Chromium Fillers FSW Dissimilar Joint of AA6063 and AA 5154
Advances in Materials Science and Engineering, Volume 2023, Issue 1, 2023., 2023 Friction stir welding (FSW) is a solid‐state metal joining process. There is no melting and recasting of metal while welding is used. Some of the defects commonly encountered in FSW are tunnel defect, bond, cracks, pin holes, and pipping defects. The defects occur because of improper metal mixing and less heat input in the weld nugget zone.

Arc characteristics and weld appearance in pulsed ultrasonic assisted GTAW process
Results in Physics, 2019 A new welding process was named as pulsed ultrasonic assisted GTAW (PU-GTAW). In low-frequency of 1–20 Hz, the arc shape went through from expansion to contraction and re-expansion with the change of pulsed frequency, which was defined as pulsed arc ...

Arc pressure and weld metal fluid flow whilst using alternating shielding gases Part 2 : arc force determination [PDF]
, 2013 The transient variation of the shielding gas present in the alternating shielding gas process produces a dynamic action within the liquid weld metal. Flow vectors opposite in direction have been reported due to the various forces acting on the weld metal
