GMAW-B: A High Productivity, High Quality Process for Joining Thick Steel Plate

In a study conducted for the National Shipbuilding Research Program (NSRP), EWI demonstrated that buried arc gas metal arc welding (GMAW-B) could be a superior method for joining thick steel metal plates with lower distortion.

This work is discussed in a paper by EWI associates Nick Kapustka and Paul Blomquist, High Penetration Buried Arc Gas Metal Arc Welding for Steel Plate Fabrication.

EWI’s Manufacturing Innovation Mission — Some Current Manifestations

By Henry Cialone
President & CEO, EWI

EWI has a mission statement. What organization doesn’t these days? But I’m not sure many people, even many directly affiliated with EWI, could articulate it precisely. That said, I do believe that many would, if asked, be able to accurately describe what we do. Because really, it’s quite simple: We help customers in manufacturing fill technical gaps with innovative solutions that ultimately make them better at what they do.

How does that mission play out in real life? It starts with looking and listening. At EWI, we continuously watch the manufacturing space and make observations about industry changes. We also regularly survey customers — formally and informally — to identify immediate and future challenges that may benefit from a range of technical services. Fundamentally, we are driven by the market and our customers’ need to adapt to it so that they can survive — and thrive.

I want to share just two of the manufacturing industry’s calls to action that we’re currently seeing and hearing…

A New Model for Predicting Next-generation Vehicle Crash Performance

The introduction of lighter and stronger metals in
automotive design is an overall win for both manufacturers and consumers. The
properties of these advanced materials, however, make crash performance
modeling a challenge. EWI has developed a new solution for predicting crash
behavior that can save automakers both time and money.

Addressing the Role of Joints in Vehicle Crash Simulations, written by Senior Technology Leader Jerry Gould, introduces this new technique, discusses its success for spot welding, and describes its potential for continuous welds.

Remote Planning Service for Automation – A Video Introduction

Last month, EWI introduced the Remote
Planning Service for Automation
, a
low-risk, low-cost, consultative program that helps manufacturers quickly
assess and develop plans to implement automation into their production
processes. The service offers an interactive, online, team-to-team approach to
resource assessment, process review, production line modification, and work
cell design.

A Remote Planning Service engagement
is conducted entirely online and is completed over a two-day period. It
eliminates the need to travel or visit to other work sites and delivers a
customized automaton plan, ready for swift deployment onto the factory floor.

Do you need to alter or enhance your production processes in response to current market circumstances? Would you like to see how selective automation can improve your operations? Find out how the Remote Planning Service for Automation works by watching this short video

To learn more about EWI’s Remote Planning Service for Automation, contact Dominic Myers at damy[email protected] or 716.710.5535.

Parallel Gap Resistance Welding — Inside the EWI Microjoining Lab

Resistance and ultrasonic processes can be superior to
soldering when it comes to joining dissimilar materials in micro-components.
Technology innovator EWI has the capabilities to do both. In this video, Senior
Engineer Tim Frech takes you inside EWI’s fully equipped microjoining lab for a
demonstration of parallel gap resistance welding of copper foil to a flex
circuit.

The advantages of this process over soldering include:

  • In-process monitoring for quality assurance
  • Reduced cycle time
  • Improved joint reliability

If you would like to learn more about EWI’s microjoining
technologies and how we can help you with your processes, contact 614.688.5152
or [email protected].

EWI and MTI to participate in DOE research project on material joint reliability

The U.S Department of Energy (DOE) Office of Fossil Energy (FE) and the National Energy Technology Laboratory (NETL) recently selected projects to receive cost-shared R&D under the opportunity announcement (FOA) DE-FOA-0002192, Extreme Environment Materials for Power Generation.

One of the projects selected is Robust Dissimilar Metal Friction Welded Spool for Enhanced Capability for Steam Power Components. General Electric Company and GE Research (Niskayuna, NY), in collaboration with EWI and Manufacturing Technology Inc. (MTI), will work to improve the durability of dissimilar metal welds (DMWs) for boiler and heat recovery steam generator applications with reduced maintenance costs and enhanced capability of coal plant cycling operations. The project will develop a durable, friction-welded dissimilar-metal spool utilizing the higher capability transition material of a nanostructured ferritic alloy and an oxidation protective coating across the joint that will be retrofittable in the existing steam fleet. Improved joint durability should enable an increase in the number of cold starts and cycling behavior of the steam fleet and reduce unplanned outages from DMW failures.

MTI is a Strategic Technology Member of EWI. To learn about their joint work in the development of low force friction welding, click here.
