  • Enhanced magnetically impelled arc butt wielding (MIAB) technology
    Patent number: 9446470
    Abstract: A magnetically impelled arc butt (MIAB) welding device heats facing ends of a pair of wellbore tubulars and a force application device compressively engages the facing ends to form a welded joint. The device may be positioned on the rig floor. The MIAB welding device may include a device configured to hold facing ends of the two wellbore tubulars at a specified distance away from one another, a high frequency arc ignition device configured to generate an arc between the facing ends and to revolve the arc around the circumference of the facing ends, and a magnetic field generator configured to superimpose a magnetic field at the facing ends. The MIAB welding device may be configured to melt at least a surface of the facing ends.
