Welcome to the Aluminum Welding Tech Cell. Here you will find information on arc welding power sources, guns and torches, welding gases, and welding wire specifically for aluminum welding.

Underwater aluminum GMAW

The U.S. Navy has been searching for new weld-repair methods on its aluminum-hulled ships beyond dry docking, which is impractical and costly. Phoenix Intl., an underwater services company that has held the Navy’s Diving Services contract for the past 15 years, may have found one: underwater aluminum GMAW in a hyperbaric chamber.

5 tips for successful aluminum GTAW

Aluminum has garnered a reputation for being difficult to weld, especially when using gas tungsten arc welding (GTAW). Mastering the process isn’t as daunting as you might think. All you really need for successful aluminum GTAW is an understanding of the metal’s unique properties and the welding preparation techniques and tools you’ll need to address those properties.

Fabricating tight ships on a tight deadline

For Great Lakes Shipyard, a division of the Great Lakes Towing Co., located on the Cuyahoga River’s Old River Channel just off of Lake Erie, one order posed the ship designer and fabricator’s biggest challenge in recent history: designing and fabricating not one but two aluminum ships, something the company had yet to do.

Aluminum welding Q&A: About soot, porosity, and equipment

What causes soot and porosity in aluminum welding? Do I need a push/pull gun with my GMAW machine to weld aluminum? Are robots practical for my aluminum application? These questions are answered in this first installment of a new column on thefabricator.com.
