AWS Class ER317L MIG & TIG is a welding wire used extensively in the manufacturing and construction industries. This filler wire is specifically designed for welding stainless steel and is used in applications that require high corrosion resistance. This blog post will discuss everything you need to know about AWS Class ER317L MIG & TIG, from its composition and physical properties to its uses and heat treatment options.
What is AWS Class ER317L MIG & TIG?
AWS Class ER317L MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas) are welding processes that join metals. MIG welding electrode uses metal wire fed through a gun-like device to melt the two pieces of filler metal. In contrast, TIG welding uses a non-consumable tungsten-coated electrode for precise control over the weld zone. Both processes require high heat to join the base materials to create strong, long-lasting joints. MIG is faster and easier than TIG but does not provide as much finesse or detail as TIG; on the other hand, Tig provides greater precision but takes longer and requires more skill. Each process has advantages and disadvantages depending on the application type it is used for.
ER317L MIG & TIG Welding Wire Composition
AWS Class ER317L MIG & TIG is a welding wire comprising 18% chromium, 13% nickel, and 3% molybdenum. It also contains small amounts of carbon, manganese, silicon, phosphorous, sulfur, and copper. The high nickel content makes it resistant to corrosion, and the molybdenum content adds strength.
