Tackling aluminum GMAW

November 22, 2010

By:

The reactive nature of aluminum to the welding arc, which is much more pronounced than that of other base materials, presents many challenges, including excess heat input and burn-through, porosity, poor bead appearance, poor fusion, and cracking. Technology advancements have made tackling these challenges easier by providing a balance of high travel speeds with a narrow, focused arc

Riding the right wave in aluminum welding

May 19, 2009

By:

Gas tungsten arc welding (GTAW), or tungsten inert gas (TIG) welding, often is thought of as the most difficult welding process to master. Fortunately for welders, several technological advances have occurred, forcing many to rethink their assumptions. Alternating current (AC) GTAW is no longer...

The pressure's on!

April 1, 2009

Massachusetts-based Woods Hole Oceanographic Institution (WHOI) is dedicated to researching the impact that oceans have on the Earth as a whole, and sometimes that means diving to treacherous depths to gather pertinent information. For an excursion at Challenger Deep, a portion of the South Pacific Ocean off the coast of the Marianas Islands, WHOI fabricated a hybrid remotely operated vehicle able to withstand the 15,751 PSI of pressure, allowing scientists to gather valuable data from more than 35,000 feet below sea level.

Aluminum Workshop: Age before welding in T6

March 24, 2009

By:

Q: In the last Aluminum Workshop, you talked about improving the welded strength of 6061 by welding in the T4 temper and aging after welding. But what happens if we weld in the T6 temper and age after welding? Does the weld get stronger, or does the extra aging cycle overage the T6 base material...
