	Weldable and unweldable aluminum alloys Frank Armao discusses which aluminum alloys are weldable, which are not, and why. Publish date: May 11, 2011
	Achieving T6 designation for 6061 Can you tell me the heat treatment steps necessary to produce 6061-T6? I have heard that heat treating it after welding will increase its mechanical properties. Publish date: March 14, 2011
	Age before welding in T6 Frank Armao discusses why weld strength increases when incorporating an aging cycle prior to welding in the T6 temper. Publish date: March 24, 2009
	Preventing porosity in humid environments Publish date: March 11, 2008
	Eliminating fine shavings from 5356 wire Publish date: January 15, 2008
	Minimizing weld cleaning stripes Frank Armao gives advice on how to minimize the appearance of cleaning stripes on polished aluminum tread plate. Publish date: September 11, 2007
	To weld or not to weld Alclad Publish date: July 10, 2007
	Aluminum Workshop I have a fabrication project involving 5454 aluminum plate, and I was told to weld this alloy using 5183 filler wire. Is this correct? Publish date: May 8, 2007
	Which filler wire is best for welding 6061-T6 aluminum, 5356 or 4043? Publish date: October 3, 2006
	Choosing a GMAW machine for occasional aluminum welding Publish date: September 25, 2003
	Inverter versus transformer power supplies for aluminum GTAW Publish date: August 28, 2003
	Welding aluminum with inverter-based power supplies It's easy to look at such a long-established technology as welding and believe that little or no technology development is taking place. In truth, however, the capabilities of welding power supplies are changing constantly and rapidly, especially in the area of inverter technology. These power... Publish date: July 24, 2003
	Al GMAW: CC or CV? For about 40 years, a great debate in welding is whether to use constant-current or constant-voltage power supplies when using gas metal arc welding on aluminum. Constant-current power supplies made sense 30 years ago and are still used in some applications today, but for most applications,... Publish date: June 12, 2003
	How to recognize, minimize weld smut Publish date: April 10, 2003
	Choosing tungsten electrode type, size for aluminum GTAW Publish date: February 27, 2003
	Preparing, testing bend samples Bend tests for aluminum are different than for steel. For instance, lack of fusion discontinuities in aluminum usually don't show up as well in radiographs. A bend test is a more discriminating way to test your aluminum weld. Publish date: September 26, 2002
	Preparing for aluminum GTAW There are right ways and wrong ways to set up welding equipment to accommodate the aluminum GTAW process. Welders should know how to troubleshoot this commonly used process and be familiar with how to solve some common welding problems. Publish date: April 24, 2001
