Once the weld pool is established tilt the torch at about a 75° angle and move smoothly and
evenly along the joint while fusing the materials together.

Tig Welding with Filler Rod Technique
In many situations with TIG welding, it is necessary to add a filler rod 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 rod 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 rob added, the rob 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 rod inside
the gas shield as this protects the end of the rod from being oxidized and contaminating the weld
pool.
