Abstract |
|
Tungsten arc welding processes are being employed widely for the precision joining of critical components which require controlled heat inputs. The small intense heat sources provided by the tungsten arc are ideally suited to the controlled melting of the material. Flux is an inorganic compound suspended in a volatile medium to increases the penetration and provide arc constriction. A variant of the TIG process by using flux called Activated-TIG process. The surface of the work piece is covered with a thin layer of the flux, which is usually a metal oxide. This layer will act as an insulation barrier to the arc current. Temperature at the centre of the weld pool will be sufficient to melt the flux so that the electric current can penetrate the flux to the weld pool and work piece. |
