  • The Influence of Water Temperature & Flow on Resistance Welding Electrode Life
    Many studies have been made to determine the best copper alloys for producing high-quality welds and long life when resistance welding steel, particularly galvanized metal. New electrode designs that use unique geometry have been developed to accomplish the same results. Many control designs can
  • Resistance Welding Fundamentals (.pdf)
    the fact that the resistance of the workpieces and electrodes are used in combination or contrast to generate the heat at their interface. Resistance welding is a fairly simple heat generation process: the passage of current through a resistance generates heat. This is the same principle used
  • Welding
    by applying heat and pressure. The temperature is usually below the melting point of the materials joined. Hot-press, ultrasonic, diffusion, and explosive welding are examples of solid-state welding. Fusion welding methods, chiefly gas, arc, and resistance, are the most widely used and are less restrictive
  • Compensating for Varying Material Conditions in Resistance Welding (.pdf)
    Unitek Equipment's advanced weld heads and closed-loop power supplies provide exceptional control over the force and energy variables in resistance welding. In addition to controlling these variables, consistent part placement and material control are required to achieve consistent welding results
  • The Importance of Squeeze Time in Resistance Welding (.pdf)
    Controlling the electrode force is a critical part of successful resistance welding. Repeatable weld force provides for consistent welds. For this reason, all Unitek Peco weld heads include a standard force-firing feature that initiates the power supply when a preset electrode force is reached
