  • Ultrasonic Testing as an Alternative to Radiography
    Kevin Cooper
    The Navy Joining Center (NJC) operated by Edison Welding Institute is working on three U.S. Navy ManTech development projects that address inspection and cladding for surface combatants and advanced weld development for the Expeditionary Fighting Vehicle (EFV). One of the projects involves uses ul...
  • What you need to know about  Friction Welding Processes What you need to know about Friction Welding Processes
    Tim Stotler
    Friction has been used to weld parts for both new make and for repair for many decades. The friction welding family of processes encompasses many different variants, including rotary friction welding (inertia, direct-drive, and radial), linear friction welding, and more recently, friction stir weldi...
  • What are Dendrites?
    Morgan Gallagher
    Have you ever heard a Metallurgist or a Welding Engineer talk about a dendritic structure, or secondary dendrite arm spacing, and wondered what those terms meant? When metals solidify, the solid/liquid interface in most cases is not planar; rather 'fingers' of solid jut forward ahead of the solidif...
  • Ultrasonic Metal Welding for Lithium-Ion Battery Cells
    Mitchell Matheny
      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 joints pose joining challenges, but of the three, welding multiple layers of foil to a tab is the most challenging. The joint is often made up of dissimilar meta...

  • What is your definition of a skilled welder?
    Jeremy Didion
    In my last blog Where are all the skilled welders I received many good answers, ideas, and comments through my social media page Linkedin. The question that kept reoccurring was 'what is the definition of a skilled welder?'. Although everyone has their own opinion, most would agree that being a s...
  • Dissimilar Materials Joining
    Richard Tenaglia
    Design engineers are increasingly faced with the need to join dissimilar materials as they are seeking creative new structures or parts with tailor-engineered properties. Sometimes a part needs high-temperature resistance in one area, good corrosion resistance in another. Structures may need toughne...
  • Reciprocating Wire Feed GMAW – An Advanced Short Circuit GMAW Mode
    Nick Kapustka
    Reciprocating 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 char...

  • Making micro-scale wire welds
    Tim Frech
    When most people hear the word “welding” they think of the guy in the local garage with an arc welder and a mask, or the army of spot welding robots used to build a car body.  You might be surprised to learn that there are many more welds in the sensors and motors in a typical car than are used to h...
