What’s New with Filler Metals?

Metal-cored wire is becoming an increasingly viable choice for improving quality and welding. Metal-cored wires offer good results in heavy equipment manufacturing and similar markets, where higher deposition rates and faster travel speeds are required to improve productivity on thicker materials.
Filler metals reflect how welding operations are evolving, as materials change to meet application demands that require technologies capable of meeting more specific — and sometimes more stringent — welding requirements.

Filler Metals: Accuracy in Ordering and Usage Matter

While filler metals comprise only small portion of the cost of a welding operation, over time they can contribute to the quality, productivity and profitability a company sees.  
It only makes up about 20 percent of the cost of your typical welding operation, but incorrectly estimating the amount of filler metal needed can have a far-reaching impact to your bottom line.

Common Causes and Cures of Hydrogen Cracking

Hydrogen can enter the weld pool in a variety of ways. Typically, hydrogen picked up during the welding process is present in the form of moisture, which can come from humidity in the atmosphere or from mill scale, grease, oils, paint or other coatings on the base material. 
Knowing the means by which hydrogen can enter the weld is a good defense against potential problems. These steps can help reduce the risk of cracking that leads to costly rework, downtime, increased labor needs, poor productivity and most importantly, product failure.

Understanding the Basics of Low-Hydrogen Stick Electrodes

When welding in the flat and horizontal positions, point/drag the electrode 5 deg to 15 deg away from the direction of travel to help reduce the chance of trapping slag in the weld. The weld bead width should usually be two and half times the diameter of the electrode’s core wire for flat and horizontal welds.
Knowing the basics about E7018 low-hydrogen stick electrodes can be helpful in understanding how to maximize their operation, their performance and the welds they can produce.

Understanding the Basics of Flux-Cored Wires

Both gas-shielded and self-shielded FCAW wires can provide higher deposition rates than solid wire or stick electrodes and are relatively easy to use, making them a more productive filler metal choice for many applications. 
As with any filler metal, welders must weigh out the advantages and disadvantages of gas-shielded and self-shielded FCAW wires to determine if these are the best choice for their specific application.
