Choosing a GMAW machine for occasional aluminum welding

September 25, 2003

By:

I want to buy a small gas metal arc welding (GMAW) machine, preferably one that runs from 120-V input power. Most of my welding will be steel, but I would like to weld aluminum occasionally. Can these machines really weld aluminum? I've heard a lot of different opinions. Some companies claim their...

Welding aluminum with inverter-based power supplies

July 24, 2003

By:

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.

Al GMAW: CC or CV?

June 12, 2003

By:

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.

How to recognize, minimize weld smut

April 10, 2003

By:

When I weld any aluminum alloy, I see a covering, light gray to black in color, over the weld. I see it when I gas tungsten arc weld (GTAW), but it's worse when I gas metal arc weld (GMAW). What is it? Does it affect the mechanical properties of the weld? How do I get rid of it?A common occurrence...

Choosing tungsten electrode type, size for aluminum GTAW

February 27, 2003

By:

I've heard different opinions about which size and type of tungsten electrode I should use to gas tungsten arc weld (GTAW) aluminum. Could you clear up this subject for me?As you know, we use direct current electrode negative (DCEN), or straight polarity, to weld steels and stainless steels. For...
