Hobart Launches New Brand Campaign

“It’s the tie that binds” celebrates the journey from the filler metals customers use to the relationships developed on the journey to find the right filler metal solution.

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.

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.

Welding Wire Meets Manganese Exposure Limits

Coreweld C6 LF offers the same enhanced features of the standard Coreweld C6, with welder-friendly operating characteristics that include consistent arc stability, very low spatter, good bead shape and minimal clean-up in an easy-to-use wire. Its low diffusible hydrogen level helps avoid hydrogen-induced cold cracking in the welding of high strength steel.
Coreweld C6 LF low manganese emission metal-cored welding wire from ESAB is ideal for hand held or automated welding in automotive, civil construction, mobile and heavy equipment, shipbuilding, rail car manufacturing and general fabrication.

Produce Weld Beads with Almost No Ripple and Little Spatter

Dual Shield II 4130 SR is ideal for welding offshore oil and gas topsides and platforms. Dual Shield II 70-Ni1 H4 provides excellent low temperature toughness in both as-welded and stress-relieved conditions.
Dual Shield II 4130 SR and Dual Shield II 70-Ni1 H4 low-alloy flux-cored wires from ESAB are excellent for all-position welding with high deposition rates and increased efficiency.

Metal-Cored Wires Remain Strong After Extensive Stress Relief

The FabCor 4130 SR exceeds AWS minimum specifications by offering a tensile strength of 107,000 psi and a yield strength of 98,000 psi, when operating with a shielding gas of 80 percent argon and 20 percent CO2. The wire also offers Charpy V-Notch impact values of 30 ft-lb at temperatures of -60 deg F (-50 deg C). The FabCOR 4130 wire is available in .045 in diameter, packaged on a 33 lb spool. 
FabCOR 4130 SR and SubCOR 4130 SR wires from Hobart are ideal for single and multi-pass welding in oil and gas and offshore applications, wellhead fabrication and repair, and others using high-strength low-alloy steels.
