Praxair's New Stargon SS Shielding Gas Blend Delivers Top Quality Welds for Stainless Steel.Business Editors
DANBURY, Conn.--(BUSINESS WIRE)--May 5, 2003
Praxair, Inc. (NYSE NYSE
See: New York Stock Exchange : PX) today announced the launch of its patented Stargon(R) SS shielding gas Shielding gases are inert or semi-inert gases that are commonly used in several welding processes, most notably gas metal arc welding and gas tungsten arc welding. Their purpose is to protect the weld area from atmospheric gases, such as oxygen, nitrogen, carbon dioxide, and water blend, a carefully controlled mixture of argon argon (är`gŏn) [Gr.,=inert], gaseous chemical element; symbol Ar; at. no. 18; at. wt. 39.948; m.p. −189.2°C;; b.p. −185.7°C;; density 1.784 grams per liter at STP; valence 0. , carbon dioxide carbon dioxide, chemical compound, CO2, a colorless, odorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of temperature and pressure. and nitrogen that is designed for joining a wide variety of stainless steels under the most challenging conditions.
"Praxair's new Stargon SS blend is an universal shielding gas for economical and convenient stainless steel welding. It is an important addition to Praxair's successful Star family of shielding gases, which also includes Praxair's StarGold (R)blends for general fabrication fabrication (fab´rikā´shn),

"Its unique formulation makes it well-suited for all-position welding and it can be used with a full range of metal transfers, such as short circuiting, pulsed and conventional spray." Coffman continued.

The addition of nitrogen 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 chemistry control is critical to maintaining micro-structural integrity and increased corrosion resistance.
"To date, our customers report that the Stargon SS blend reduces spatter spatter,

"It also offers cost savings when compared with the high-helium content mixtures currently used today."
With consistency at every pressure throughout the application process, the Stargon SS blend eliminates residual gas waste from stratification, thereby reducing costs. This consistent and homogeneous blend is the result of Praxair's Starblend(TM) gas mixing system, designed specifically for argon-based blends that use carbon dioxide.
"This new shielding gas blend reinforces Praxair's leading position as a total solutions, service-based provider, assisting our customers in controlling and reducing manufacturing costs," said Hickl. "Our productivity specialists use Praxair's exclusive StarSolver(R) Productivity Enhancement Program to accurately and systematically analyze customers' different types of welding and cutting processes, including robotics and laser applications. And where appropriate, we recommend process changes to improve their production performance," he added. "This is especially important for assessing the impact of labor and overhead, which account for 85 percent of overall welding costs."
