ION A filler metal is a metal added in the
making of joint during welding, brazing and soldering.(Ref: ASME Section IX, Definitions)
Filler wire is in wire and particle form.

• Base metal = SA 335 • Welding process = GTAW• Filler wire = ?????
Referring ASME Section IX, Table QW-422, we will find where does this material (base metal) lies and find its:
• Grade• P number• Chemical composition
