  • Single-sided welding head
    Patent number: 11684996
    Abstract: Described herein is a single-sided welding head including a first welding electrode and a second welding electrode, where the first and second welding electrodes are carried by a body of said welding head. The first welding electrode is movable relative to the body of said welding head at least along a first coordinate of motion. The second welding electrode is movable relative to the body of said welding head at least along a second coordinate of motion; where said first coordinate of motion is a coordinate of angular motion that develops about a first axis of rotation, and said second coordinate of motion is a coordinate of linear motion that develops along a first axis of translation.
    Type: Grant

  • Electric resistance welding head with electrodes located on the same side
    Patent number: 10695859
    Abstract: An electronically-controlled electric resistance welding head and method having a support structure and the electrodes located on the same side. The welding head including a ground electrode having an elastic device and a detecting device for detecting a force load on the elastic device on contact with a component to be welded. A welding electrode is movable relative to the ground electrode and the support structure to contact the component to be welded. An electronic control unit is operable to selectively increase the force applied by each electrode when in contact with the component to be welded until respective threshold values are achieved. Current is generated by a transformer for passage to the electrodes.
