**Q&A: ER70S-2 vs ER70S-6 TIG: Choosing the Best Option**.
1. What are ER70S-2 and ER70S-6?
ER70S-2 and ER70S-6 are both specifications for welding wire used in TIG welding processes. They are both high-quality solid wires that are commonly used for welding mild steel.
2. What are the differences between ER70S-2 and ER70S-6?
ER70S-2 has a higher level of deoxidizers compared to ER70S-6, which makes it more suitable for welding on surfaces that have contaminants or oxidation. ER70S-2 is also known for providing cleaner welds with less spatter.
ER70S-6, on the other hand, contains more deoxidizers such as silicon and manganese, which makes it a better choice for welding on dirty or rusty materials. It also offers higher tensile strength and better impact resistance compared to ER70S-2.
3. How do I choose between ER70S-2 and ER70S-6 for TIG welding?
When deciding between ER70S-2 and ER70S-6 for TIG welding, consider the condition of the material you will be welding. If you are working with clean materials and want a cleaner weld with less spatter, ER70S-2 may be the better option. However, if you are dealing with dirty or rusty materials that require higher tensile strength and better impact resistance, ER70S-6 would be more suitable.
Ultimately, the choice between ER70S-2 and ER70S-6 will depend on the specific requirements of your welding project and the properties you prioritize in the final weld. Both wires are excellent choices for TIG welding mild steel, so selecting the best option will depend on the specific needs of your project.
