Our Arc Welding Expertise
Since EWI’s founding over 30 years ago, we have been enhancing and optimizing arc welding processes to benefit all manufacturing sectors.
Specializing in welding, cladding, repair, large-scale additive manufacturing, and more, we’ve developed and launched technologies for applications ranging from ship building and jet engines to oil and gas fabrication.
Because so many of our clients have unique goals, we focus on not only the deliberate application of arc welding technology but also on lesser-considered – but highly important – systemic details:
- Developing novel repair technologies for highly engineered alloys
- Guiding the implementation process through completion
EWI’s arc welding team is an industry authority in consumable and non-consumable electrode arc welding processes. Our expertise is broad, and we keep it that way with relentless innovation. We’ve developed specialties in progressive arc-based applications for complex metal builds and repairs, such as directed energy deposition (DED), a type of additive manufacturing utilizing robotic path planning.
WE MANUFACTURE INNOVATION.
Put simply, we dive into the nuances of the arc welding process and materials to help our clients meet complex goals in the most productive, cost-effective manner – whether we’re modifying existing processes or starting with big ideas alone.
Making It Work
In order to efficiently leverage the arc-based processes we know so well, we approach each project with careful attention to developing procedures and complying with applicable standards and codes. These are important aspects of our arc welding engagements – just as important as the technologies themselves.
- Parameter development and optimization
- Procedure development
- Adherence to codes and standards
- Design for welding and design reviews
- Customized training
- Process comparison and down-selection
- Feasibility studies
- Feature-based qualification
- Cooperative research programs
- Site evaluations
Directed Energy Deposition (DED) Expertise
A cutting-edge EWI capability, directed energy deposition (DED) is a type of additive manufacturing utilizing a robotic arm, lasers and either powder or wire for complex metal builds. For many applications, DED can be faster than other methods of additive manufacturing, and its accuracy reduces the need for machining after an additive part has been produced. At EWI, we can utilize CAD-to-path (robotic path planning) to build at multiple angles. This allows us to not only build solutions for new applications but also to use DED for making repairs and adjusting features.
We greet tough goals with excitement, leveraging cross-departmental strengths and staying engaged with our clients from idea to production. With this perspective, we’ve developed arc welding solutions for these unique applications:
- Applying reciprocating-wire-feed GMAW to components made of crack-sensitive material – surrounding heat-sensitive fluid and components – without the use of preheat
- Automating the repair of austenitic manganese steel trackwork components for the Federal Railroad Administration, increasing the service life of these expensive high-wear components by over 200% and reducing lost track time
- Investigating the effects of welding techniques, electrode chemistry, and shielding gas on GMAW stainless steel-clad layers for a fabricator of nuclear components and vessels
Through inventiveness, our clients’ trust and collaboration, and decades of combined experience, our arc welding team has accomplished considerable feats – from setting industry standards for GMAW procedures to enabling intricate welds strong enough for outer space. Let us meet your organization’s challenges.
