| 41. | Arc welding uses electricity to melt the surfaces of the metals in order to join them together through generators.
|
| 42. | Russian inventions include arc welding by Nikolay Benardos, further developed by Nikolay Slavyanov, Konstantin Khrenov and other Russian engineers.
|
| 43. | A related process, plasma arc welding, also uses a tungsten electrode but uses plasma gas to make the arc.
|
| 44. | Robot arc welding has begun growing quickly just recently, and already it commands about 20 % of industrial robot applications.
|
| 45. | The relatively new procedure of arc welding was used extensively throughout the ship, strengthening the durability of the armour plating.
|
| 46. | Motoman's arc welding system also has safety features to prevent anyone from wandering near the welder while it is operating.
|
| 47. | This was one of the very first standards that covers friction stir welding, although it actually focuses on arc welding.
|
| 48. | Working conditions are much improved over other arc welding processes since the flux hides the arc and no smoke is produced.
|
| 49. | Copper has excellent brazing and soldering properties and can be welded; the best results are obtained with gas metal arc welding.
|
| 50. | Spark gap oscillators are still used to generate high frequency high voltage to initiate welding arcs in gas tungsten arc welding.
