Gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) are both regularly used for welding aluminum. GTAW is a slow process when compared to GMAW and GMAW is typically used when extremely high weld quality (with respect to porosity) is not required. GMAW works well for welding aluminum in structural, automotive, or thick […]
Read MoreLightweighting is an important focus for design folks in the automotive and aerospace worlds. Reducing the weight of a vehicle helps to improve fuel economy and reducing the weight of an airplane additionally enables more cargo to be carried. Magnesium-Aluminum-Zinc (Mg-Al-Zn) alloys have the highest strength to weight ratios of structural metals. AZ31B (Mg-3Al-1Zn) is […]
Read MoreWell folks, Movember is upon us. Some of you call this no-shave November and use it as an excuse to grow a beard or a goatee or something like that. It is officially called Movember and growing a sweet moustache is the proper way to raise awareness and money for men’s health issues. Prostate cancer […]

Read MoreI’m not sure if “politicing” is used appropriately as a verb (kind of like “efforting”), but it seems accurate for what is happening these days around the deficit. On the positive side, the media is continuing to publicize the deficit as the major issue for the candidates to address. But in this case, “address” is […]

Read MoreLast week, a writer for TMS met with Ed Herderick, an applications engineer in EWI‘s Materials Group, to talk about the workshop he’s planning with TMS experts on the topic of ICME (integrated computational materials engineering). See what Ed had to say about why it’s the right time for this workshop, and why a roadmap for […]
Read MoreWhen using a consumable-electrode process such as gas metal arc welding (GMAW) or submerged arc welding (SAW), the three primary process variables are arc current, wire feed speed (the rate at which the consumable electrode is fed from the welding torch), and arc voltage. Current and wire-feed-speed cannot be varied independently. To maintain the same […]
