Understanding TIG Welding Filler Rods
What Is TIG Welding?
TIG (Tungsten Inert Gas) welding, also known as GTAW (Gas Tungsten Arc Welding), is a precise welding process that employs a non-consumable tungsten electrode to produce the weld. Filler rods are often used to add material to the weld joint, especially when welding thicker materials or achieving specific mechanical properties.
Role of Filler Rods in TIG Welding
Filler rods serve as the material that melts and fuses with the base metal, creating a strong and durable joint. Selecting the correct filler rod is crucial because it influences:
- The integrity of the weld
- Compatibility with the base material
- The aesthetic finish
- Mechanical properties such as strength and corrosion resistance

How to Interpret a TIG Welding Filler Rod Chart PDF
Key Components of the Chart
Most filler rod charts in PDF format will include the following sections:
- Material type (e.g., stainless steel, aluminum, carbon steel)
- Filler rod alloy designation (e.g., ER70S-6, ER308L)
- Diameter options
- Recommended welding parameters
- Compatibility notes
Understanding Material Designations
Filler rod designations often follow standards set by organizations like AWS (American Welding Society). For example:
- ER70S-6: Mild steel filler suitable for general-purpose welding
- ER308L: Stainless steel filler for 304 stainless steel
- ER4043: Aluminum filler for 6xxx series aluminum alloys
These codes help identify the alloy composition and intended use.
Matching Filler Rods to Base Materials
The chart typically categorizes materials to help select the right filler:
- Carbon steels
- Alloy steels
- Stainless steels
- Aluminum and aluminum alloys
- Other metals like copper or nickel alloys
Matching the filler to the base material ensures metallurgical compatibility and weld quality.
Common Filler Rods and Their Applications
Steel Filler Rods
- ER70S-3 / ER70S-6: Used for general mild steel welding
- ER80S-D2: For high-strength steels
- ER308L / ER316L: For stainless steel welding
Aluminum Filler Rods
- ER4043: Suitable for welding 6xxx series aluminum alloys
- ER5356: Used for 5xxx series aluminum, offers better corrosion resistance
- ER1100: For pure aluminum welding
Other Filler Materials
- Nickel alloys (e.g., ERNiCr-3): For high-temperature and corrosion-resistant applications
- Copper alloys: For electrical and thermal conductivity
Creating a Custom TIG Welding Filler Rod Chart PDF
Steps to Develop Your Own Chart
1. Gather Material Data: Collect information on the metals you frequently work with, including alloy types and specifications.
