Using Metal-Cored Wire with Pulsed MIG to Weld Galvanized Steel

High strength galvanized steel is an excellent material to help automotive manufacturers build lighter-weight vehicles, but it can present some challenges that make it difficult to weld.

Industry Standards Are Evolving Faster Than Ever

Fuel economy mandates are dictating significant design changes to new vehicles and trailers. To comply with these changes, shops must learn new techniques while training technicians to weld aluminum in addition to steel. To reduce the already expensive overhead costs auto body and repair facilities endure, it is critical that the welding machine provides versatility and timesaving features.
For auto body shops or tractor repair facilities to effectively keep up with the new demands being driven by fuel economy mandates and remain profitable, they must invest in easy to use equipment that is capable of welding both steel and aluminum.

Blueprint for the Future

Pulsed MIG welding is effective in welding higher-strength steels and galvanized steels. Synergic pulsed MIG welding systems that communicate completely between the power source, feeder and gun are popular in welding materials such as aluminum. With a standard Pulsed MIG system that is not synergic, a welding operator must manually change other settings when changing the wire feed speed. With a synergic system, changes in wire feed speed automatically adjust other settings for a constant welding arc, greater control and better weld quality. 
Fabricators must continually explore new technologies that will grow along with their operations to help them stay competitive, profitable, productive, and ahead of the curve so they are prepared for the demands of the future. 

How Multiprocess Welders Address Heavy Fabrication Challenges

For operations that have a need for multiple welding processes such as TIG, MIG and Stick in various applications, multiprocess machines offer versatility and can have significant benefits for quality, productivity and efficiency in industries that include construction, shipbuilding and heavy fabrication.
The combination of new engineering with improved and reliable current technology for single source TIG, MIG and/or Stick welding and carbon arc gouging can really increase the operating profitability of jobsites and fabrication shops.

The Pride of the Pipeline

Manual welding with a PipeWorx 400 multiprocess power source that does RMD and Pulsed MIG welding. Changeover is quick because there is no need to manually switch polarity or cables and hoses between processes. Welders can also trigger through pre-set programs while at the welding joint to eliminate walking back and resetting the machine.
By changing welding processes, this oil and gas production equipment manufacturer cut more than 200 man-hours out of each product to thrive during the shale gas boom.

How Electronic Fuel Injection Technology Improves Efficiency of Engine-Driven Welding Power Sources

Electronic Fuel Injection (EFI) has been used for decades and is standard in many cars, but it’s a technology that’s fairly new to the smaller engines used in gasoline-powered engine-driven welding power sources. Incorporating EFI technology results in reduced emissions and provides numerous other benefits in welding and construction applications, including increased fuel efficiency.
As contractors and welders continually look for ways to reduce welding costs and be more efficient, things as simple as engine choice can make quite a difference.

Remote Control Technology Simplifies Ease of Use for Welders

Miller has expanded its ArcReach remote control technology to three additional machines: the XMT 350 CC/CV, XMT 450 CC/CV and Dimension 650 multiprocess welding power sources.  ArcReach allows welding operators to adjust and set voltage at the point of use — the weld joint — without the use of control cords, reducing downtime and improving safety by reducing exposure to tripping hazards and lessening operator fatigue associated with walking to and from the power source. The technology also eliminates the need to settle for less-than-optimal welding parameters, which helps improve weld quality, and it increases productivity by providing for more time to weld.
By providing complete control of voltage at the weld joint – without the use of control cords — ArcReach technology from Miller Electric helps welders improve their productivity, quality and safety.  

More Flexibility for All

The unique “smart MIG” function on the Rebel EMP 215ic welding system from ESAB enables users to begin MIG welding with an extremely stable arc just by setting metal thickness and wire diameter. There is no need to enter information for shielding gas mix. The Rebel provides an industrial quality arc for MIG, flux-cored, Lift TIG and Stick welding, including excellent performance with difficult-to-weld E6010 electrodes. 
The search for a “one-size-fits-all” welding solution continues to uncover new equipment that increasingly offers more flexible welding solutions suited for both large and small shops, with better options to do better business.

Green Welding Machine Line Expands

The refreshed and expanded green welding line from Forney is designed with the welding and do-it-yourself (DIY) enthusiast and first-time user in mind.
Forney has also introduced a complete line of nearly 130 new soldering products to round out its full-service product lines for the auto enthusiast, farm and ranch customer, industrial/consumer welder and the do-it-yourselfer.
