Choosing the correct gas delivery system for metalworking

September 9, 2013 | By John Karpus

Supplying gas to your metalworking applications can be complicated, especially if the gas needs to reach multiple locations. If you are looking for cost savings and productivity gains, consider installing gas cylinders at one main location and controlling them with a basic manifold or switchover manifold. With this method you won’t need to worry about cylinders running out of gas.

Corrosion-resistant fabrication project enhances nuclear power station’s cooling system

September 6, 2013 | By Eric Lundin

Nuclear power plants use a lot of water to cool the reactors, and when the water intake unit occasionally pulls in a sea lion or a shark, environmentalists go nuts. Dimic Steel Tech bid on a contract to build two huge grates for Southern California Edison to keep marine life out of the water intakes, and had to learn a bit about welding corrosion-resistant steel along the way.

Demystifying contact tips

September 5, 2013 | By Rudy Simmons

Contact tips are highly misunderstood components in a welding gun setup. Choosing the correct contact tip for your welding application and understanding how to keep it performing at its best are just as critical as anything else needed to produce a quality weld.

Need a filler metal for a 300 series stainless steel?

June 28, 2013 | By David Benson

Matching a consumable to a 300-series (austenitic) stainless steel is fairly straightforward, but fabricators should be aware that the various options (rod for GTAW, solid or metal-cored wire for GMAW, stick electrode for SMAW, or flux-cored wire for FCAW) have huge productivity differences.

The impact of impact toughness

March 15, 2013 | By Robert Fox

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 Dan Davis

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.

Horizontal fillet test troubles

May 11, 2011

For a recently acquired large structural job, we have had to qualify a single-pass 5⁄16-in. fillet using 0.045-in. E71T-9M flux-cored wire. We are having trouble passing the horizontal fillet test. When performing the weld break test on the horizontal fillet weld, there is incomplete...

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.

Demystifying metal-cored wires

March 14, 2011 | By Tim Hensley

Even though metal-cored wires have been gaining popularity in recent years, there seems to be some mystery and misconceptions surrounding this filler metal. To better understand these wires it helps to consider the technology behind them and the applications for which they are best suited. Additionally, it is important to know the general characteristics of metal-cored wires, along with the ways they can provide potential improvements in the welding operation.
