Today’s market has many gas shielded flux cored arc welding (FCAW) wires. The task of selecting the right wire for a particular application can be intimidating and confusing. The majority of FCAW wires that are common to the heavy fabrication steel industry are categorized into just two types: rutile flux wires and basic flux wires. […]
Read MoreEWI has made rapid advances in developing fluxless ultrasonic soldering technology as well as develop a cost-effective Pb-free solder that could potentially help make soldering more environmentally friendly. Conventional soldering be it manual, reflow or wave, requires the use of flux to prevent the formation of surface oxides and to enable wetting of the solder […]
Read MoreShipyards typically use submerged arc welding (SAW), flux cored arc welding (FCAW) or gas metal arc welding (GMAW) to fabricate butt joints in thick steel plate. But there are drawbacks to these traditional welding methods, such as the necessity for weld joint preparation. In addition, multiple welds are often required to fill the joint. Now, […]
Read MoreA standard electric vehicle (EV) automotive battery can be decomposed into cell level, module level, and pack level. A cell mainly includes the anodes and cathodes, a module includes multiple cells, and a pack includes multiple modules. The three most common metal-to-metal joints in a lithium-ion battery pack are foil-to-tab, tab-to-tab, and tab-to-bus. All three […]
Read MoreWelding of dissimilar polymers is becoming more commonplace in manufacturing. There are several key reasons for this trend. First, many new plastics are being used in environments where adhesives cannot be easily applied. Typical examples include medical products for which finding adhesives that pass FDA regulations and join materials with low surface energy (like polyolefins) […]
Read MoreVehicle electrification systems are comprised of batteries, cables, inverters, motors, and other high-power electrical devices. Electric systems depend on the reliable interconnection of these components. Requirements go beyond joint strength; joints must be vibration resistant and have low electrical resistance, high current carrying capacity, and high thermal conductivity. EWI has worked on interconnects for different […]

Read MoreFor some time, EWI DeepTIG has been available in specialized flux formulas for carbon steel, stainless steel, and nickel-based alloys. Now, a more user-friendly version of the product, EWI DeepTIG wire, is also available and can be used like any other welding filler metal. The advantage is that penetration can be increased 250%-300% compared to conventional welds made with solid wire.
Read MoreEWI DeepTIG™ flux enhances penetration and reduces passes in GTAW. A new cored-wire version of the product reduces the preparation steps and increase penetration 250-300% over conventional solid-wire welds. This paper discusses the research and benefits. Download the Paper
Read MoreThe Virginia Coalfield Economic Development Authority has closed on a $509,000+ grant to the Buchanan County Industrial Development Authority to implement a cybersecurity pilot program designed to create jobs in the cybersecurity field. The project, developed by EWI, will serve to mentor students to learn network monitoring skills through an on-the-job training cooperative aimed at assisting small and medium size manufacturers.
