While this may not be a surprise to EWI associates and partners, its great recognition for the leading-edge work – including nine patents between 2006 and 2010 – developed by our small corps of engineers. COLUMBUS BUSINESS […]
Read MoreGas 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 MoreHave you ever thought back and reflected upon how you chose your career? As a child, what input did you receive that shaped your aspirations?

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 MoreSubmerged arc welding (SAW) is a high deposition rate process when compared to gas metal arc welding (GMAW) or gas tungsten arc welding (GTAW). Certain applications such as large flat panels, girth welds in pipe, or spiral pipe mills can benefit from techniques used to increase the deposition rate, and consequently, the productivity of the […]
Read MorePlasma arc welding (PAW) is very similar to gas tungsten arc welding (GTAW). If you look at the schematic shown in Figure 1 you can see that the arc in PAW is created between a non-consumable tungsten electrode and is constricted by passing through an orifice. This provides a more columnar arc with a higher […]
