Read MoreOn Saturday, March 5th, EWI and OSU’s Welding Engineering program hosted an 8-hour Boys Scout Welding Merit Badge clinic. The participants received hands-on instruction in gas metal arc welding and were coached and evaluated on their welding skill using the Lincoln Electric RealWeld System. They also learned about thermal cutting and non-arc welding processes, first aid, […]
Read MoreIt is amazing what a little drive, ambition, and perhaps fear can do… EWI engineer Marc Purslow completed his epic cross-country bicycle journey late last month. It started with a desire to do something big that mattered. Back in August 2013, he decided to ride his bicycle across the country – all the way from […]
Read MoreArc-welding robots have been around for decades and are used in many industries, including heavy manufacturing, automotive, aerospace, and ship building. Historically, the knowledge and skill required to implement arc-welding robots has been substantial and may have discouraged first-time robot users. In recent years, however, robotic welding equipment manufacturers and integrators have advanced the level […]
Read MoreMil-E-24403/1 and AWS A5.20 specifications (“D” and “Q” designators) have their requirements on low and high heat inputs to qualify a FCAW wire in addition to the control of pre-heat and inter-pass temperatures. A specified heat input is an average heat input for all passes in a test assembly. AWS A5.20 / 17.2 even applies […]
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 MoreEWI hosted a welding merit badge clinic on Saturday 13 April for Boy Scouts in Columbus and the surrounding areas. The welding merit badge is one of the newest in scouting. It is the 128th current merit badge and was released on Feb. 24, 2012. The event was held at the EWI facility in Columbus […]
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 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 […]
