What is Welding?
Process of joining similar metals, (or thermoplastic)
- By heating them to suitable temperature
- May or may not require pressure.
- May or may not require Filler metal
What is Brazing ?
Process of joining dis-similar metals, by melting and pouring the filler metal.
- Both the metals are pre-heated to a suitable temperature
- Filler metals fills the joint gap by capillary action
What is an Welding Electrode ?
- An Current Conductor in which a arc is created at its edge due to minor air gap between itself and its oppositely charged Conductor
- An Electrode may be consumable (such as in SMAW/ GMAW) or Non Consumable (such as in Electric Resistance Weld / TIG Weld)
What is a Filler Metal in Welding ?
- Additional metal used for joining of two metals during the process of welding or Brazing or Soldering.
- A Filler metal may be a separate Rod / Wire / Powder / Consumable Insert or it may also be a consumable Electrode (such as in SMAW or GMAW weld)
Difference between Filler metal and Electrode:
- Both are related to ARC Welding Process
- Electrode is that which carries current to the job in the welding circuit and Filler metals is that fills the required area with metals.
- But in a few Welding Process the Electrode also acts as a Filler metals by becoming a consumable electrode (Example: Manual Metal Arc Welding, Gas Metal Arc Welding, Flux Cored Arc Welding,Submerged Arc Welding )
What is F Number for Electrodes?
F Number is a designation used for Grouping of Filler metals based on their usability and make selection of alternate filler metals easy when it comes to a Welder Qualifications and Welding
Procedure Qualification
