Get a piece of aluminum about ½ to 1 in. thick. This is so you can put out a lot of current without melting it. Set your power supply on AC between 120 and 150 amps. Strike an arc and slowly move it along the surface of the plate for 3 or 4 in. Don't worry about adding filler wire or even forming a weld puddle.

The rectification effect mechanism of the Cu TE device is proposed in terms of the energy band diagram in Fig. 5.Note that the conduction mechanism of the Al TE device has been already investigated [25].Fig. 5 a shows the energy band alignment of Cu, TiO 2, and Al.The work functions of Cu and Al, and the electron affinity and the band gap …

An explanation of arc rectification. The phenomenon of arc rectification normally manifests itself as a fluttering in the arc of a gas tungsten arc welding (GTAW) machine. You'll notice this flutter in both the look and sound of the arc, and this instability can prevent the arc from heating the metal enough to get a solid, consistent weld.

Additionally, they eliminate the expense and complexities involved in experimental fabrication and testing, and the empirical nature of the employed models ensured high accuracy of results. ... For instance, Rogers experimentally demonstrated up to thermal rectification across a steel–aluminium interface in a vacuum environment ...
