Understanding the Basics of Flux-Cored Wires

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.

Stick Welding Still Has a Place in the Fabrication Industry

The reasons for using stick welding vary. Fabricators may need greater access to the weld joint (where a MIG gun won’t reach) due to a complicated configuration. Or in some cases, the process may be specified for a given welding procedure. Welding on outdoor applications also benefits from stick welding since it’s very portable — it doesn’t require external shielding gas cylinders or a wire feeder. 
Many applications in the fabrication industry still require stick welding. Like other filler metals, stick electrodes are available in many types, each of which provide different mechanical properties and operate with a specific type of welding power source. Before you power up your machine and pick up your stick electrode holder, consider these basic guidelines to help simplify your stick welding experience. 

Characteristics of Heat Treatable vs. Non Heat Treatable Aluminum Alloys

Most of the commonly used filler alloys will not respond to post-weld heat treatment without substantial dilution with the heat-treatable base alloy. This is not always easy to achieve and can be difficult to control consistently. For this reason, filler alloys have been developed to independently respond to heat-treatment.  
There are certainly differences in strengths for aluminum alloys, whether they are heat-treatable or not. These different characteristics impact the final strength of the weld because these alloys differ in their chemical and metallurgical structure and in how they react during the welding process.

Four Things You Must Know About Metal-Cored Wire

Because metal-cored wires can weld through mill scale and light rust, they can often eliminate pre-weld activities like grinding, sandblasting or adding anti-spatter before the welding process begins. This feature can also eliminate or reduce the cost for purchasing grinding wheels and anti-spatter solution.
In recent years, metal-cored wires have become an increasingly common option to enhance productivity, improve quality and reduce costs in the metal fabrication industry. Here are four important details about metal-cored wire that shops should know if they are considering a filler metal conversion.

Metal-Cored Wire Offers Higher Deposition Rates, Faster Travel Speeds to Increase Productivity

The new FabCOR F6 gas-shielded metal-cored wire new provides higher deposition rates and increases productivity on single-pass, flat and horizontal welding applications, particularly when compared to solid wires.
FabCOR® F6 wire from Hobart Brothers provides higher deposition rates and faster travel speeds to help increase productivity on single-pass, flat and horizontal welding applications, with deposition efficiencies similar to solid wire but with reduced spatter to minimize clean up.

Flux-Cored Wires Offer Lowest Manganese Levels in the Marketplace

The new Element™ wires reduce manganese emissions to help address the increasingly strict requirements and recommendations of regulatory bodies such as ACGIH and OSHA. 
Through the the innovative formulation of the flux fill, Element™ wires from Hobart Brothers produce manganese emissions well below the levels of other gas-shielded flux-cored wires without sacrificing mechanical properties or weldability. They provide very low spatter levels and consistent arc stability that ensures reliable welding performance on a variety of applications.

Aluminum Filler Metals Approved for Wrought Commercial Applications
