As a full-service fabrication company dedicated to providing the Saratoga Springs area with affordable, high-quality services, we have extensive experience in welding. While we specialize in robotic arc welding for its precision and efficiency, we are also well-versed in various other welding methods. In this blog post, we will explore some of the most commonly used techniques when working with stainless steel. Stainless steel is an iron-based alloy containing at least 10.5% chromium. This element forms a thin, protective layer of chromium oxide on the surface, which gives the material excellent corrosion resistance. Depending on their composition, stainless steels can be categorized into five main types: ferritic, duplex, austenitic, martensitic, and precipitation-hardening. These types vary in magnetic properties and are further divided into series such as 200, 300, 400, and 600 based on their chemical makeup. Stainless steel is generally considered to be easy to weld, thanks to its good workability and compatibility with multiple welding processes, including spot, resistance, electron-beam, arc, MIG, and friction welding. However, proper preparation is essential. The surface must be thoroughly cleaned before welding, and the type of stainless steel being used should be known to ensure the best results. One important consideration is that stainless steel has about 50% higher thermal expansion than carbon steel. This means it retains more heat during welding, so less heat input is required. It also has better electrical conductivity, making it easier to work with in resistance welding applications. Certain types of stainless steel require special attention during the welding process: The best welding method depends on factors like the grade, thickness, and finish of the stainless steel. While there are several options, three are most commonly used: TIG welding, also known as tungsten inert gas welding, is widely used for thin materials like stainless steel and non-ferrous metals such as aluminum and copper. It uses a tungsten electrode to create a low-heat-input weld. A common technique involves using an inert backing gas on one side of the joint to protect against oxidation and improve corrosion resistance. MIG (Metal Inert Gas) welding is a semi-automatic process that uses a solid wire electrode and a shielding gas, typically argon-rich. It’s ideal for creating strong, consistent welds and is often used in industrial settings. The arc between the wire and the metal melts the surfaces, allowing them to fuse together. Gas mixtures like helium, oxygen, or CO2 are sometimes used to stabilize the arc and improve weld quality. Spot welding is a cost-effective and efficient method, especially for joining thin materials like sheet metal or wire mesh. It works by applying pressure and electric current to create a localized heat source that fuses the materials together. This method is widely used in the automotive industry for assembling frames and panels. It can also be fully automated using robotic systems for consistent and reliable results. Stainless steel is a versatile material used in everything from cookware and surgical instruments to construction and industrial equipment. Despite its higher initial cost, it offers long-term value due to its durability, low maintenance, and resistance to corrosion and heat. When combined with advanced fabrication technologies like CNC machines, laser cutters, and robotic welders, stainless steel becomes even more accessible and efficient to work with. With over 60 different grades available, stainless steel offers a wide range of options to suit any application. Combining these options with a fabrication shop equipped with cutting-edge technology ensures that your project is completed efficiently and effectively.
