“Measure twice, cut once.” If you’re like me, this is something I never forget to do… except when I forget to do it and end up making my 4th trip back to the Home Depot dropping another $45. What’s my point? The EWI modeling group is the equivalent of a really, really good tape measure. […]
Read MoreYou are invited to join us to celebrate the grand opening of EWI’s new Metro Detroit office in Madison Heights, Michigan. Come to our Open House to meet our Associates, learn about our local partner Easom Automation Systems, see demonstrations of our new technologies, and find out more about what EWI can do for your […]
Read MoreAn area where EWI is expanding its knowledge is in characterizing and cataloging mechanical properties of additively manufactured metals (metals AM). The work described here was performed to obtain baseline mechanical property data for Ti 6-4 ELI weld metal buildups that were produced using hot-wire gas tungsten arc welding (GTAW-HW). The equipment used to weld […]
Read MoreIn a lot of ways EWI is not different than other companies. There are deadlines and budgets; cuts and investments to make; and a lot of the same stresses you have at your company. As CFO, I hear the same gripes I’m sure other controllers and CFO’s hear… “why can’t we do (fill in the […]
Read MoreHere’s a test to see if you’re a Common Man… If I asked you (95% of the people reading this blog) to describe what welding is, I’m guessing you would describe one of two things: Arcs and/or Sparks. When I started here at EWI as CFO, I pictured either a guy flipping down his welding […]
Read MoreMore and more, robotic welding is becoming a viable option for use in heavy fabrication. The sophistication and capacity of modern robot systems is suitable for large structures which require multi-pass welds. Processes used for heavy fabrication such as preheating, gas metal arc welding (GMAW), flux cored arc welding (FCAW), tandem gas metal arc welding […]
Read MoreFriction Stir Welding (FSW) is an advanced welding process that uses a third body (often called the “tool” or “pin”) to generate frictional heat between two parts to create a solid-state bond. Originally developed for thin sheet aluminum, the process has now been adapted for a variety of materials from soft metals (aluminum, copper, magnesium, lead) to […]
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 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 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 […]
