Considerations for Switching to Pulsed MIG and Pulsed TIG Welding in Thin Gauge Aluminum Applications

Tuesday, February 28th, 2012

Pulsed welding equipment has been around for a long time. However, technical advancements have made pulsed welding equipment much easier to use and, consequently, better for training operators to make quality welds. Some of the new Pulsed MIG and Pulsed TIG welding technologies provide excellent welding performance on thin gauge aluminum.

Upgrading to modern Pulsed MIG or Pulsed TIG inverter technology could potentially help you increase productivity, improve weld quality, reduce weld costs, and boost operator efficiency. That being said, you will need to study your particular application in detail to determine which, if any, of these processes is appropriate for you. Remember, pulse welding is not the answer to all aluminum welding-related problems.

Case Study: Bollinger Shipyards and the AlumaFeed System

Friday, June 3rd, 2011

You’ll be hearing a lot from us over the next few months on aluminum. One of the first things we’d like to share with you is this great snapshot of the aluminum welding needs at Bollinger Shipyards in Lockport, La.

Read the whole story here. After the excerpt, see what the folks at Bollinger Shipyards had to say about Miller’s AlumaFeed™ System.

Aluminum is increasingly specified in marine applications because it’s lighter without sacrificing strength and functionality. This makes ships faster, saves on fuel, and provides them with excellent anti-corrosive properties. It does, however, present difficulties: distortion, cleanliness, aesthetics, burn through and difficult wire feeding, to name a few.

To best meet these challenges, Bollinger overhauled its entire aluminum welding facility to include a new bulk gas delivery system, wall-mounted booms for wire feeders, and new AlumaFeed™ synergic aluminum welding systems from Miller Electric Mfg. Co. The system is designed to simplify and improve MIG and Pulsed MIG aluminum welding applications and has proven a good fit at Bollinger.

Improvements include: Hours saved in productivity, thanks to the synergic controls; reduced distortion and burn through, thanks to the Pulsed MIG capabilities; the aesthetics of a TIG weld with the production speeds of MIG welding; less bird nesting, thanks to advanced wire feeding technology; switch to a larger diameter wire, which allows for faster travel speeds.
