Praxair's Stargon® SS gas blend is a carefully controlled blend of argon, carbon dioxide and nitrogen that is designed for joining a wide variety of stainless steels. It is well-suited for all-position welding as it can be used with all types of metal transfer (i.e. short circuiting, pulsed, and conventional spray). It produces excellent quality welds when joining light gauge material with short-circuiting transfer and offers cost savings when compared with the high-helium content gases currently used today.
With its controlled CO2 content, the Stargon SS blend can be utilized in most austenitic stainless steel applications, particularly where weld metal carbon control is required. The addition of nitrogen to the Stargon SS blend enhances arc performance by increasing its stability, improves weld penetration, and reduces distortion in the welded part. It also assists in maintaining weld metal nitrogen levels for materials such as duplex stainless steels where such chemistry control is critical to maintaining microstructural integrity and increased corrosion resistance.
