When it comes to mild welding steel, using the right TIG filler rod is essential. The quality of your weld will depend on your choice of rod, so it’s important to understand what type of rod you should be using and why. Let’s take a look at why choosing the right TIG filler rod matters and how to make the best choice for your mild steel welding projects.
Why Does It Matter?
Using the correct TIG filler rod when welding mild steel is critical because different rods have different levels of strength and are used in different applications. For instance, some rods may produce welds that are more ductile or malleable than others, which can be important when joining two pieces together. Additionally, some rods may have higher levels of corrosion resistance than others, which is important if you’re welding outdoors or in a humid environment. Knowing what type of rod to use is key to achieving the desired result with your welded joint.
Types of TIG Filler Rods for Mild Steel Welding
When it comes to mild welding steel with a TIG welder, one popular option is the ER70S-2 filler rod. This type of rod produces welds that are highly ductile with excellent mechanical properties and high levels of corrosion resistance. It also has good gap-bridging capabilities, making it suitable for welding thicker pieces together without having to perform multiple passes. Another option is the ER70S-6 filler rod, which produces strong welds with good impact strength but lower levels of corrosion resistance compared to ER70S-2. Finally, the E70T-5 filler rod can be used for high-temperature applications such as those found in boilers or furnaces due to its ability to withstand temperatures up to 450°C (842°F).
Choosing the right TIG filler rod for your mild steel welding project is essential for achieving the desired results. Different types of rods produce welds with different properties depending on their composition and intended application—so be sure you select the right one! Taking all these factors into consideration will help ensure you get the best possible results from your next mild steel welding job.
