Mild Steel Tig Filler Rods: A15 And Its Properties
When it comes to TIG welding, choosing the right filler rods is crucial. For mild steel applications, the most commonly used filler rod is A15. A15 is a copper-coated triple de-oxidized mild steel rod that offers a variety of properties that make it ideal for welding mild steel.
One of the key properties of A15 is its high de-oxidizing ability. This means that it helps to remove impurities from the weld pool, resulting in cleaner, stronger welds. The copper coating also contributes to this de-oxidizing effect, as it helps prevent oxidation during the welding process.
Another important property of A15 is its excellent flow characteristics. This means that the filler rod melts evenly and smoothly, allowing for easier control of the weld pool. The result is a more precise and aesthetically pleasing weld.
In addition, A15 offers good penetration, which is essential for achieving strong welds in thick materials. With its combination of de-oxidizing ability, flow characteristics, and penetration, A15 is an excellent choice for TIG welding mild steel.
- A15 is a copper-coated triple de-oxidized mild steel rod
- A15 has high de-oxidizing ability for cleaner, stronger welds
- Copper coating prevents oxidation during welding
- A15 has excellent flow characteristics for better control
- Good penetration for strong welds in thick materials
Ac Tig Welding: Aluminum Filler Rods 4043A And Alloy 5356
When it comes to AC TIG welding, aluminum filler rods are the go-to choice. Two commonly used aluminum filler rods are 4043A and Aluminum Magnesium Alloy 5356. These filler rods are specifically designed for AC TIG welding and offer a range of benefits.
4043A is a popular choice for general-purpose aluminum welding. It provides good flow characteristics, allowing for smooth and controlled welding. It also offers excellent crack resistance and is suitable for welding a variety of aluminum alloys.
Aluminum Magnesium Alloy 5356, on the other hand, is known for its high strength and superior corrosion resistance. It is commonly used for welding marine-grade aluminum alloys and is suitable for applications where high strength and durability are required.
Both 4043A and Alloy 5356 provide excellent penetration and weld pool control, making them versatile options for AC TIG welding aluminum. Their flow characteristics ensure aesthetic and precise welds, while their specific properties cater to different applications.
Stainless Steel Tig Filler Rods: 316L And 308
For stainless steel TIG welding, 316L and 308 are commonly used filler rods. Each of these filler rods has its own unique properties that make it suitable for different applications.
316L is a popular choice for stainless steel TIG welding due to its excellent corrosion resistance and high-temperature strength. It is often used in applications requiring resistance to chemicals and acids, making it ideal for food-grade and marine-grade applications.
On the other hand, 308 is a more cost-effective option for stainless steel TIG welding, particularly for 304 sheet material. While it may not offer the same level of corrosion resistance as 316L, it still provides sufficient strength and durability for many applications.
Both 316L and 308 filler rods offer good flow characteristics and penetration, ensuring clean and strong welds. The choice between these two filler rods often depends on the specific corrosion resistance requirements and budget constraints of the project.
Considerations For Food Grade And Marine Grade Applications
When working with materials that require food-grade or marine-grade applications, choosing the right filler rod is crucial. These applications require materials that are not only strong and durable but also resistant to corrosion and chemicals.
For food-grade applications, 316L stainless steel filler rods are the preferred choice. They offer excellent corrosion resistance, making them suitable for the food and beverage industry. The smooth and clean welds achieved with 316L ensure that there are no crevices or pockets for bacteria to thrive, meeting the strict hygiene requirements of the industry.
When it comes to marine-grade applications, aluminum alloy filler rods like Alloy 5356 are the go-to option. This filler rod provides superior corrosion resistance, ensuring that the welds can withstand the harsh marine environment. The strength and durability of Alloy 5356 make it suitable for structural components and vessels that are exposed to saltwater and other corrosive elements.
It is essential to consider the specific requirements of food-grade and marine-grade applications when choosing filler rods. Using the appropriate filler rod ensures that the welds will meet the necessary standards and provide long-lasting performance.

Frequently Asked Questions
What type of welding is filler rod used in?
Filler rods are commonly used in TIG welding, which stands for tungsten inert gas welding. In this welding process, a non-consumed tungsten electrode is used to generate heat, while the filler rod is manually added to join the metals together. It resembles gas welding in terms of the process, but differs in the heat source employed. The filler rod plays a crucial role in TIG welding, as it melts and forms the bond between the two metals being joined.
What is the most common filler rod?
The most common filler rod in automotive shops is the ER70S-6. This versatile filler rod is specifically designed for mild steel and is widely used for various applications such as sheet metal, chassis, and suspension components.
