	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 supplies are suitable for welding aluminum alloys, including thin aluminum alloys. Publish date: July 24, 2003 Tech cell: Aluminum Welding
	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, constant-voltage power supplies are suitable for gas metal arc welding aluminum.

	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 Tech cell: Welding Inspection
	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 Tech cell: Aluminum Welding
