6.5 Pulsed Arc

With the pulsed arc, the material transfer is precisely controlled by pulses
(Figure 17).

In the base current phase, the energy input is reduced to such an extent that the
arc barely burns steadily and the surface of the workpiece is preheated. In the
pulsing current phase, an accurately timed current pulse guarantees a precise
detachment of the weld droplet.

Fig. 17: The pulsed arc.

The pulsed arc almost completely eliminates unwanted short-circuits and simul-
taneous droplet explosions. As a result there is virtually no uncontrolled spatter
with the pulsed arc.

6.6 Combined Arcs

Combined arcs are often made up of pulsed arcs and dip transfer arcs
(Figure 18).

Fig. 18: Combined arcs.

The penetration and heat input needed are generated in the pulsed arc phase.
The dip transfer arc phase takes care of the cooling in the weld pool, thus
ensuring better controllability of the weld pool.

7.2.5 HOT-Start

Um die Elektrode leichter zünden zu können, wird beim HOT-Start am Schweiß-

gerät bei der Zündung für den Bruchteil einer Sekunde der Strom erhöht.

7.2.6 SOFT-Start

Die SOFT-Start-Methode wird speziell bei basischen Elektroden während des

Zündvorgangs genutzt, um die Porenbildung zu reduzieren.

5.10.2 TIG Welding with Alternating Current

TIG welding with alternating current is used with aluminum and magnesium.

The oxide layer (Al

) has a melting point of approximately 2,050 °C, while

2O3

aluminum itself has a melting point of approximately 650 °C, depending on the
alloy. Where there is an oxide layer on the material, it is not possible to create
a welded joint as the metal would  ow away in droplet form. The alternating
current destroys or displaces the oxide layer, thereby making welding possible.

TIG welding with alternating current is also known as TIG AC
welding.

The “cleaning half cycle” (electrode on the positive pole) alternates with a “cool­ing half cycle” (electrode on the negative pole). As a result of this alternation

There are exceptional cases in which light metals are TIG welded with direct
current. In such cases, the tungsten electrode is connected to the negative pole
and helium is used as the shielding gas.
