Arc-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 MoreNew York State has confirmed its investment plans for the new advanced manufacturing institute to be operated by EWI in Buffalo. The announcement to dedicate $45 million for the new center was made last week. This allocation will fund facilities, equipment, and start-up operations for the first five years, after which the institute will be self-sustaining. Activities […]
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 MoreAccording to an article in the current issue of FABRICATING AND MANUFACTURING magazine, RealWeld Systems offers a game-changing step forward in professional welding training. The RealWeld Trainer, developed by EWI, provides data-driven live feedback to welders, making it an ideal tool for training, retraining, and skills evaluation in large welding shops. […]
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 […]
Read MoreWhile doing a comparison between two widely used steel structural welding codes, I found a difference that may cause users of the codes to choose welding electrodes differently. The two codes are AWS http://www.aws.org/w/a/ D1.1 and Eurocode 3 (Here I mean EN 1993 1-8 for those who prefer a higher number to letter ratio). In […]
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 […]
