EWI DuraStir EWI has been on the leading edge of Friction Stir Welding (FSW) since its inception in the early 1990s. We have advanced FSW for hard metals with EWI DuraStir and EWI DuraStir for R&D. These proprietary tools are used to weld hard metals such as steels, titanium, and nickel-based alloys using FSW. EWI […]
Read MoreIn-Service Welding Guidelines In-Service Welding Guidelines provides best practices for welding on in-service pipes under a broad variety of conditions and situations. EWI Titanium Weld Color Inspection Kit This kit is considered the standard for visual inspection of titanium weldments across all industries. EWI DeepTIG® EWI DeepTIG® for gas tungsten arc welding (GTAW) helps increase […]
Read MoreOn October 19, EWI hosted an industry-wide workshop in Detroit to discuss current technical challenges in materials joining and metal forming. The underlying theme for the workshop was the recently completed NIST-funded Comprehensive Advanced Materials Joining and Forming Technology Roadmap, developed in concert with several joining and forming experts. One objective of the workshop was to […]
Read MoreEWI has purchased an industry-leading electron beam melting (EBM) system from Arcam AB, a top provider of metal additive manufacturing (AM) solutions.
Read MoreThe AweSim program at the Ohio Supercomputer Center (OSC) and EWI have been selected to develop one of 10 national industry projects under the U.S. Department of Energy’s (DOE) High Performance Computing for Manufacturing (HPC4Mfg) program. AweSim and EWI will partner with Oak Ridge National Laboratories (ORNL) to develop a cloud-based advanced welding simulation […]
Read MoreResonance fatigue of tubular steel goods has become a relatively common method of testing fatigue life of full circumference welded joints. EWI has maintained a system for such tests for many years and has conducted several standard qualification programs of steel riser welds for offshore applications. However, we have also employed the resonance fatigue system […]
Read MoreEWI is capable of performing orbital welding, a specialized welding process whereby the arc is rotated mechanically around a static workpiece such as a pipe in a continuous process. The technique was developed over 50 years ago, and with today’s modern technology is a sound, robust, and easy-to-use method of joining cylindrical components. These components can be […]
Read MoreReciprocating wire feed gas metal arc welding (RWF-GMAW) is a low heat input, precisely controlled variation of the GMAW process. With the RWF-GMAW process the wire is reciprocated in and out of the weld pool. The wire motion is synchronized with the current waveform to produce a weld that is characterized as having minimal if […]
Read MoreThe 7th International Seminar on Joining Aerospace Materials will be held September 17-18, 2014, Organized by EWI and TWI, the biennial event is attended by leading technologists and engineers involved in state-of-the-art aerospace manufacturing and assembly of aircraft structures. The upcoming event will be hosted by Boeing at the Boeing Longacres Customer Center outside of Seattle, Washington. Topics […]
Read MoreCladded metal plates (clads) are widely used in the refinery industry. Explosion welding is one of popular joining processes to produce those clads. ASTM codes on the explosion welding of stainless steels and nickel alloys, such as ASTM A263, 264, and A265, allow a cladded layer to be considered to bare structure loads under the […]
