Increasing Aluminum Weld Strength and Quality

Aluminum is popular in many fabrication applications, but welding the material presents challenges of cracking, porosity and burn-through on thinner sections. Here are some critical insights on how to combat these potential problems.

Weathering Steel: Taking the Guesswork Out of Filler Metal Selection

Weathering steels have small additions copper, nickel and chromium that help improve the corrosion resistance of the steel to atmospheric sources. 
Weathering steel offers excellent resistance to atmospheric corrosion caused by rain, snow or humidity. During the welding process, the filler metal type and the manner in which it is applied determines whether the resulting weld will match corrosion resistance or have the same reddish appearance, more commonly known as color match.

Considerations When Selecting a Filler Metal (Part Two)

Filler metal has a significant impact on the quality, productivity and cost of a welding job, so it’s worthwhile to take the time to make the right selection.
Although the effect of various elements in filler metals can be rather complex, a review of their general properties can also help welding operators determine which filler metal is ideal for the job. It is important to consider the properties needed in a completed weld when making the filler metal selection.

Ways to Get the Most Out of Your MIG Gun Consumables

Nozzles should be cleaned at least every other welding cycle in a robotic welding operation to prevent spatter buildup that can lead to poor gas shielding or cause short-circuiting between the contact tip and nozzle. Heavy-duty consumables are recommended for high-temperature robotic welding applications. If the robotic welding operation calls for a heavy-duty retaining head, pair it with heavy-duty contact tips. Always check the torques of the body tube and end fittings regularly to prevent loose fitting cables that can cause overheating and lead the robotic MIG gun to prematurely fail.
Here are a few of the best practices that every welding operator should know when it comes to choosing and maintaining nozzles, contact tips, retaining heads and gas diffusers, and cable.

Matching Filler Metals to Stainless Steels

Hardfacing caster roll. Hard martensitic stainless steel is often used in high-wear applications, such as overlays and for building up wear-resistant material, and less for joining. With a high interpass temperature, it’s imperative to reach an accurate preheat temperature and maintain the minimum interpass temperature the entire welding time. If not, there is a risk of cracking.
Welding stainless remains complicated. Besides paying close attention to heating and cooling the stainless, the filler metal must be properly matched to the base metal with electrodes of the same grade. 

Considerations When Selecting a Filler Metal (Part One)

Having the right filler metal for the job can have a significant impact on quality, productivity and cost. Different filler metals provide varying mechanical and chemical properties — but in every case, the welds they create must be able to withstand the service conditions they will encounter.
Filler metal selection is critical to maintain the integrity of the final weldment. Here is a review of their general properties that can help you determine which filler metal is ideal for the job.

New Welding Wire Withstands Extreme Heat Conditions

Weld Mold 5551 flux-cored wire is well suited for extreme welding applications because of its higher physical properties and its performance ability to excel in higher temperatures. It is highly resistant to heat checking in environments where coolants are used, extremely abrasion resistant and tolerant of compressive loads. In addition, with a 30 percent higher deposition rating than typical flux-cored wire, it offers high weldability for general welding applications.
Costing about 50 percent less than comparable cobalt materials, 5551 flux-cored wire from Weld Mold retains superior hardness in temperatures up to 1,200 deg F.

New Wire Offers Higher Deposition Rates and Travel Speeds for Welding Heavy Equipment

FabCO 85HXP gas-shielded flux-cored wire is well suited for flat and horizontal welding of up to 6 in to 8 in thick materials used in earth moving equipment, non-alloyed and fine grain steels, heavy fabrication applications and manufacturing equipment used in severe service conditions. The wire features a basic slag system that provides increased toughness, along with excellent low temperature impact strength. Its low hydrogen levels help mitigate cracking risks and costly rework. 
Ideal for heavy equipment welding and for equipment used in severe service conditions, the new FabCO 85HXP gas-shielded flux-cored wire from Hobart Brothers can operate at higher wire feed speeds to increase deposition rates and travel speeds on thicker materials for higher productivity.

Gas-Shielded Flux-Cored Wires Lower Manganese Emissions Even More

FabCO Element 71C and FabCO Element 71M wires help address increasingly stringent environmental regulations and recommendations. In addition to low manganese levels, both the Element 71C and Element 71M wires offer enhanced out-of-position capabilities, making it easier for welding operators to create quality welds regardless of joint placement. The wires produce low spatter levels to minimize post-weld cleaning, and have a fast-freezing, easy-to-remove slag to reduce the risk of slag inclusions.
FabCO Element 71C and 71M wires from Hobart are ideal for welding in shipbuilding, structural steel, heavy equipment manufacturing and general fabrication.
