3. OBJECTIVE

4. Purpose
Learn about filler wires and their selection
OBJECTIVE
Outcome
Learn about ASME Section IX Table QW-422
Learn to find F-numbers
Chemical composition
Finding SFA number and its detail
Knowledge about ASME Section II part C
Manual books of brand

5. INTRODUCTION

6. INTRODUCTION 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.

7. DIFFERENCE B/W FILLER
WIRE & ELECTRODE

8. DIFF B/W FILLER WIRE
The basic difference is of coating
& ELECTRODE
With coating = Electrode (E)
Without coating = Filler wire (ER)

9. NOMENCLATURE

10. NOMENCLATURE
Filler wires can be divided into two
designations:
a) Mandatory classification Designators
b) Optional supplementary Designators

12. EXAMPLES FOR SELECTION
OF FILLER WIRES

13. • 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

21. Material Grade = TP304L
Welding process = GTAW
Filler wire = ????

27. ADDITIONAL INFORMATION

28. CONCLUSION

29. CONCLUSION
• Selection of filler wire depends on:
 Welding process
 Base metal
 SFA
 Joints
• Reference
 ASME Section IX
 ASME Section II part C
