TIG Welding with Filler Wire Technique
It is necessary in many situations with TIG welding to add a
filler wire into the weld pool to build up weld reinforcement
and create a strong weld. Once the arc is started the torch tungsten is held in place until a weld
pool is created, a circular movement of the
tungsten will assist is creating a weld pool of the desired size. Once the weld pool is established
tilt the torch at about a 75° angle and move smoothly and evenly along the joint. The filler metal
is introduced to the leading edge of the weld pool. The filler wire is usually held at about a 15°
angle and fed into the leading edge of the molten pool, the arc will melt the filler wire into the
weld pool as the torch is moved forward. Also a dabbing technique can be used to control the
amount of filler wire added, the wire is fed into the molten pool and retracted in a repeating
sequence as the torch is moved slowly and evenly forward. It is important during the welding
to keep the molten end of the filler wire inside the gas shield as this protects the end of the wire
from being oxidised and contaminating the weld pool.
