What is stainless steel welding rod
Stainless steel welding rods are specialized consumables used for stainless steel welding. They consist of a core and a coating. Their core function is to ensure the composition and properties of the weld metal match those of the base material.
The core is typically made of stainless steel wire of the corresponding grade (e.g., austenitic stainless steel core contains 18% Cr-8% Ni, while ferritic core contains 12%-17% Cr), which directly determines the alloy base of the weld metal. The coating, composed of arc stabilizers, slag formers, deoxidizers, and alloy powders, stabilizes the arc, forms a slag that protects the weld pool from air intrusion, and supplements alloying elements to enhance the corrosion resistance and mechanical properties of the weld.
Common grades, classified by compatible base material, include E308 (compatible with 18-8 austenitic stainless steel), E309 (for welding dissimilar steels), and E316 (containing Mo to enhance resistance to intergranular corrosion and seawater). It is widely used in pressure vessels, food machinery, medical equipment, shipbuilding and other fields. It can ensure that the weld has corrosion resistance, strength and plasticity comparable to the parent material. It is a key material for controlling welding quality in stainless steel structure manufacturing.
What is E308-16?
The E308-16 is a widely used austenitic stainless steel welding rod, a key model in the E308 series, suitable for welding similar austenitic stainless steel structures.
In the model number, "E" represents the electrode; "308" indicates that the deposited metal composition matches 308 stainless steel, containing approximately 18% Cr and 8% Ni, ensuring excellent corrosion resistance and ductility in the weld. "-16" designates the low-hydrogen potassium coating, using a mixture of titanium calcium and low-hydrogen slag. It can be used with either AC or DC reverse polarity, offering stable arc, excellent slag removal, and aesthetically pleasing welds.
This electrode is primarily used for welding 18-8 austenitic stainless steel (such as 304 stainless steel), and is particularly well-suited for applications requiring welds with general corrosion resistance and excellent mechanical properties, such as food processing equipment, medical devices, chemical pipelines, and pressure vessels. Its weld metal exhibits strong crack resistance, effectively preventing thermal cracking during welding, making it a popular choice for stainless steel welding that balances processability and performance.

FAQ
Q: What materials are suitable for welding with E308-16 electrodes?
A: E308-16 electrodes are primarily suitable for welding austenitic stainless steels such as 0Cr19Ni9 and 0Cr19Ni11Ti. They can also be used for welding some less weldable steels (such as high-chromium steels) and for cladding stainless steel surfaces.
Q: Can E308-16 electrodes be used for welding in low-temperature environments?
A: The weld metal of E308-16 electrodes maintains good impact toughness at -196°C, making them suitable for welding stainless steel structures in low-temperature environments. However, appropriate adjustment of welding process parameters and necessary low-temperature impact testing should be performed.
Q: What is the difference between E308-16 and E308L-16?
A: The primary difference lies in the carbon content. E308-16 has a carbon content of ≤0.08%, while E308L-16 is an ultra-low carbon type with a carbon content of ≤0.03%. L-shaped welding rods offer improved resistance to intergranular corrosion and are suitable for applications requiring higher corrosion resistance, especially when post-weld solution treatment is not possible.
Q: Why should welding rods be baked before use? What is the baking temperature and time?
A: The purpose of baking welding rods is to remove moisture from the coating and prevent defects such as porosity and hydrogen-induced cracking during welding. E308-16 welding rods should be baked at 250°C for one hour before use. After baking, they should be stored in an insulated container at 80-100°C and removed from the container between uses. If the welding rod is exposed to air for more than four hours, it should be rebaked, but the number of rebaking cycles should not exceed three.
Q: How can I tell if an E308-16 welding rod is genuine?
A: The authenticity can be distinguished from the counterfeit from the following aspects: 1) Check whether the packaging is standardized and whether there is a clear brand logo, implementation standard and production batch number; 2) Check whether the welding rod coating is uniform and whether there is any cracking or falling off; 3) Check whether there is a clear model mark on the end of the welding rod; 4) Purchase through formal channels and ask for a quality certificate; 5) If necessary, chemical composition and mechanical property tests can be carried out.
