Applications

3.1.1

TIG hot wire welding

The TIG hot wire welding system technology is based on the TIG cold wire welding system technology.
A wire feed system transports the wire-like welding consumable, which is heated at the stick-out between
contact tip and weld pool contact point by means of resistance heating. A second power source is
required for this resistance heating. Its secondary power circuit is closed by the wire's permanent contact
with the weld pool. The process of pre-heating the wire can be controlled in a wide range by the selected
hot wire power.
By pre-heating the wire, the energy taken from the weld pool for melting the wire can be reduced. This
allows a significantly larger amount of welding consumables to be used at a higher welding speed, thus
reducing the energy per unit length.
3.1.2

TIG cold wire welding

Cold wire welding is a variant of TIG welding featuring mechanically fed filler material. With this process,
cold welding wire is melted, without power, in the arc of a tungsten electrode.
