Abstract : A study was made to determine the feasibility of butt welding pipes by means of a magnetically-driven, rotating arc struck between the pipe rims. The two pipes served as electrodes, and two coils placed near the arc formed an opposing magnetic field to provide the Lorentz force necessary for arc rotation. A parametric study of the motion of the arc was performed, and it was concluded that the use of a rotating arc in a welding apparatus employing the Pressure Welding technique is feasible. Limitations of the test model prevented complete evaluation of the process. (Author)
