The impact of impact toughness

March 15, 2013

By:

Choosing a filler metal with the right mechanical and chemical properties for your application is critical. Correct properties not only ensure the proper weld strength, but may also help prevent costly complications. In applications that endure rapid or cyclic loading, experience extreme service temperatures, or are subject to other stressors that threaten the integrity of the weld, using a filler metal that provides the proper impact toughness is especially important.

What's up with helium for welding applications?

December 3, 2012

By:

Helium has been hard to get for some, and certainly the consumable gas is more expensive for welders than it used to be. The bad news is that this may be the case for some time. The good news is that alternatives are under development to help welders out as they tackle aluminum and stainless steel welding.

High-argon wire welds

Advancements in FCAW

May 11, 2011

Flux-cored welding is growing in popularity, yet its dependence on high concentrations of CO2 has prevented fabrication shops that employ a bulk gas delivery system from using the process. Recently wires have been developed that utilize a higher content of argon and a lower content of CO2. The result is a wire that provides low spatter, less welding fumes, and higher out-of-position deposition rates, as well as excellent weld characteristics in the vertical and overhead positions.

Welding chrome-moly steel

September 8, 2010

By:

Welding chrome-moly tube and pipe conventionally is done with shielded metal arc welding (SMAW) or submerged arc welding (SAW). Flux-cored arc welding (FCAW) has been tried, but the wires had some drawbacks that prevented widespread acceptance. Recent developments have reduced some of these disadvantages, so GMAW deserves a fresh look. The switch might lead to improvements in the weld's characteristics or welding productivity.
