This document discusses the selection of filler wires. It begins with an objective to learn about filler wires, ASME Section IX Table QW-422 for material grades and chemical compositions, and SFA numbers. It then introduces the differences between filler wires and electrodes, and the nomenclature used for filler wires. Examples are provided for selecting the correct filler wire based on the base metal, welding process, and referring to ASME standards. The conclusion emphasizes that filler wire selection depends on the welding process, base metal, joint type, and referencing ASME codes.

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 = ????

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
