  • Welding arc penetrating power real-time detection system
    Patent number: 6518545
    Abstract: A process for control of a butt welding of tubes is disclosed wherein readily measurable parameters of a process of welding are read, voltage and current, and parameters such as impedance or time interval across a portion of a pulse are derived from the voltage and current. The derived values are then used in conjunction with parameters of the welding machine to set the values of the welding machine and the torch or torches connected to it to control the power of penetration of a welding arc for no piercing but with penetration.
