AWS Shipbuilding & Aluminum Conference Intercontinental Hotel, New Orleans, Louisiana September 17-18, 2019 Three EWI associates will be presenting as part of the Shipbuilding Conference Program: Jacob Hay, Applications Engineer, Hybrid Laser Arc Welding – Application and Implementation, Tuesday 9/17 at 9:00 am Paul Blomquist, Business Development Director of Maritime Technology, Tele-Welding: Remote Operation of […]
Read MoreVirtually all ship designs utilize copper-nickel alloys for applications such as fire mains and other seawater/freshwater piping, tanks, and structures such as rope guards and fairings. The manual gas tungsten arc welding (GTAW) process that is typically used to weld copper-nickel pipe joints has relatively low productivity due to slow travel speeds and low deposition […]
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 MoreCopper-nickel alloys are often used in shipbuilding for applications such as tanks, seawater and freshwater piping, and numerous other structures. Copper-nickel pipe joints are typically welded with manual gas tungsten arc welding; however, inherently slow travel speeds and low deposition rates impede productivity. The implementation of pulsed gas metal arc welding (GMAW-P) could yield significant […]

Read MoreFABTECH is always an information-packed meeting for me. This year, advances in computer technology and information sharing capability was a strong theme with equipment suppliers. New types and improvements in welding consumables were also noteworthy. Welder training devices, including a couple that EWI helped to develop, were drawing crowds in several booths. EWI engineers had […]
Read MoreCross-industry lightweighting initiatives have significantly increased the use of aluminum and magnesium in fabrication; however, welding of these alloys presents a unique set of challenges. Arc welding processes offer significant advantages ranging from relatively low equipment costs and high productivity levels, with a range of process variations available to address productivity and quality requirements. A […]

Aluminum and Magnesium alloys are of significant interest and arc welding variations are often the process of choice for lightweighting in automotive manufacturing. This article provides an overview of potential joining processes, common […]
Read MoreEWI applications engineer Nick Kapustka and business development manager Paul Blomquist were published in the May 2015 issue of Welding Journal. In the article “Improved Welding of Primer-Coated Steels,” the authors address welding problems associated with preconstruction primers (PCPs), also called weld-through primers. The GMAW and FCAW pulse welding variants are discussed with test results. The work presented in this article was funded by […]
Read MoreEWI Applications Engineer Nick Kapustka was published in the April 2015 issue of Welding Journal. In his article “Achieving Higher Productivity Rates Using Reciprocating Wire Feed Gas Metal Arc Welding,” the author compares this process with short-circuit gas metal arc welding modes and other welding methods. Read more about it in the April issue of Welding Journal. The article is available to AWS members by […]
