The world’s supply of helium is finite and with a growing demand, prices continue to climb. When MIG welding stainless steel, helium’s thermal conductive properties help to produce fine and flat welds. Stargon™ SS shielding gas blend is able to duplicate the arc characteristics of helium welding blends with its unique composition, while offering significant cost savings.
Praxair’s Stargon SS welding gas blend is a carefully controlled blend of argon, carbon dioxide and nitrogen. It is designed for welding a variety of thick or thin stainless steels in all positions and performs well in short circuit, spray and pulsed spray welding modes.
Praxair’s argon-based Stargon SS shielding gas blend doesn’t require higher arc voltages like helium-based blends. High arc voltages increase heat input into the weld, which affects product quality when welding thin materials.
Stargon SS blend allows for lower welding voltages, compared to helium blends. This means less heat input during welding, resulting in less metal distortion. Lower heat input using Stargon SS blend also decreases sensitization of the chrome in the weld, thus improving corrosion resistance in the weldment. This makes Stargon SS blend an ideal blend for sheet metal and thin-gauge applications.
