Microstructural Evolution in Nonvacuum Solid‐State Diffusion Bonded Joints of AA2219
Advances in Materials Science and Engineering, Volume 2023, Issue 1, 2023., 2023 Solid‐state diffusion bonding of AA2219 alloy is carried out under the nonvacuum condition to form AA2219/AA2219 joints. In the currently adopted method, AA2219 alloys are joined under the bonding temperature of 450–500°C, bonding pressure of 10 MPa, and bonding time of 30 min.

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 ...

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.
