When it comes to TIG welding, choosing the right filler material is crucial for producing high-quality welds. Two common options for filler wire are ER70S-2 and ER70S-6. While both wires are suitable for TIG welding, there are some key differences between the two that can affect the final result of your weld.
ER70S-2 is a filler wire that is commonly used for welding on mild steel. It contains higher levels of silicon and manganese compared to ER70S-6, which can help improve the fluidity of the weld puddle and the overall weld quality. This additional flux also results in a cleaner weld with minimal splatter, making it a popular choice for applications where the appearance of the weld is important.
On the other hand, ER70S-6 is a versatile filler wire that can be used for welding a variety of materials, including mild steel, low alloy steel, and stainless steel. It contains higher levels of deoxidizers, such as manganese and silicon, which help remove impurities from the weld pool and prevent porosity. This makes ER70S-6 a good choice for welding thick materials or in applications where porosity is a concern.
One of the main differences between ER70S-2 and ER70S-6 is their tensile strength. ER70S-6 has a higher tensile strength than ER70S-2, which can be beneficial when welding materials that require greater structural integrity. This can result in stronger, more durable welds that are better able to withstand mechanical stress.
Another factor to consider when choosing between ER70S-2 and ER70S-6 is their welding performance. ER70S-2 is known for its smooth arc characteristics, making it easy to control and ideal for beginners or less experienced welders. On the other hand, ER70S-6 has a higher level of deoxidizers, which can result in a more fluid weld puddle and better wetting action, making it suitable for more experienced welders who are looking for improved weld quality.
In terms of cost, ER70S-6 is typically slightly more expensive than ER70S-2. However, the higher cost is often justified by the improved welding performance and weld quality that ER70S-6 provides. Additionally, the higher tensile strength of ER70S-6 can result in cost savings in the long run by reducing the need for rework or repairs due to weak welds.
When deciding between ER70S-2 and ER70S-6 for TIG welding, it is important to consider the specific requirements of the job and the material being welded. If appearance and cleanliness are a priority, ER70S-2 may be the better choice. However, if strength and performance are more important, ER70S-6 may be the preferred option.
Ultimately, both ER70S-2 and ER70S-6 are suitable filler wires for TIG welding and can produce high-quality welds when used properly. By understanding the differences between the two wires and considering the specific needs of the job, welders can select the best filler wire for their TIG welding projects.
