  • Ultrasonic Metal Welding for Lithium-Ion Battery Cells
    Steve Massey
    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 metals, the me...
  • 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...
  • 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...

  • Joining Tantalum to a Ferritic Stainless Steel
    Kirk Cooper
    Refractory metals such as Ta, Nb, Mo, and W possess excellent corrosion resistance in many environments.  They offer significant strength at high temperatures.  While these elements are often alloyed with other non-refractory metals, their high-temperature strength and corrosion resistance are usual...

  • 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...
