prepared boron- and phosphorus-incorporated tetrahedral amorphous carbon films deposited by the filtered cathodic vacuum arc process and tested the crystal growth, surfaces, interfaces, thin films, and bulk materials of the films [16].
Complexity in the arc process makes it difficult to be modeled, because many factors such as the arc line, the amount of coolness and the geometric figure cannot be defined with high certainty.
The NRC report also questioned the short circuit arc process used by the supplier who built the glove boxes.

Submerged Arc Welding (SAW) is a semiautomatic or fully automatic consumable electrode arc process in which the arc is protected by a granule, fusible flux which blankets the weld puddle and surrounds the base metal to protect it from the atmosphere.
I C Jindal, MSL manufactures spring steel flats, high strength deformed steel bars, and thermo-mechanically treated bars through the electric arc process. MSL was reconstituted as a closely held public company in 1995.
In order to avoid these problems a hybrid welding technique has been developed, which combines the laser welding process with an arc process, namely hybrid laser-arc welding.
The Sub Arc DC 650 and Sub Arc DC 1000 are optimized for the sub arc process while providing air carbon, arc cutting and gouging, stick, and flux cored capabilities.
It can be configured to weld with either the MIG or flux-cored arc process and the Spoolmate 3035 or Spoolmate 100 guns enable it to weld aluminum with mild or stainless steel.
At its height, four Divisions were involved, including a team at Applied Physics (now Industrial Physics) who adapted a plasma arc process (like that used in arc welding) to destroy ozone-depleting substances such as halons (once used in fire extinguishers) and CFCs (the banned refrigerants).
