Copper to SS Welding

When it comes to welding, there are a variety of metals and techniques that can be used for the job. One method that is often overlooked is copper-to-stainless steel welding. Copper to stainless steel (SS) welding offers a number of advantages over other types of welding, including strong joints, high-temperature strength, and excellent corrosion resistance. Let’s take a closer look at this specialized process

Process of Copper to SS Welding

Copper to SS welding involves the use of an inert gas like argon as a shielding medium during the welding process. This helps keep oxidation levels low and prevents contamination from materials such as oxygen or nitrogen. The copper is then heated with an inert tungsten gas (TIG) torch until it reaches its melting point, which is just above 2,000 degrees Fahrenheit. Once the metal has melted completely, it is then fed into the joint area between the two pieces being welded together. As the copper cools and solidifies, it forms a strong bond between the two pieces of metal.

Benefits of Copper to Stainless Steel Welding

Besides being very strong and durable, copper-to-SS welding offers several other benefits compared with other types of welding processes. For example, it requires less heat input than most other types of welding processes and produces fewer harmful fumes during use. It also provides superior corrosion resistance due to its ability to form an oxide layer on its surface when exposed to air or water vapors. Additionally, since this type of welding does not require an electric current to join metals together, it can be done in areas where electricity may not be available or accessible.


Copper to stainless steel welding can be used for various applications in many industries, from automotive repair shops and shipbuilding yards all the way up through industrial manufacturing plants and power plants. By understanding how this process works and what makes it unique compared with other types of welding techniques, novice welders can confidently tackle projects involving these two metals while achieving desirable results every time!
