In this paper, the same poles, pref. south poles, of the magnets surround the closed weld path and are pref. united in a closed path by connection to a radially split ring.Abstract:
The same poles, pref. south poles, of the magnets surround the closed weld path and are pref. united in a closed path by connection to a radially split ring. The magnets may be electromagnets and individual magnets may be supplied with different currents. The appts is esp. for welding tube ends and rings and produces a strong field concn. even when welding small components.read more

TL;DR: In the magnetically-moved arc welding of hollow metallic bodies using an internal coil unit which is aligned along the interior of the hollow body and which has a radially directed pole plate matching the cross-section of the body and extending to near the weld seam line, the magnetic induction in the gap between the pole plate and the seam line is locally varied over the periphery of the poleplate.

TL;DR: An electrical arc welding device for two workpieces to be welded together along an annular weld seam, e.g., ends of pipe sections, and in which a magnet arrangement surrounds the welding-seam path is described in this article.
Patent
Apparatus for electric arc welding with magnetically moved arc
TL;DR: In this article, the magnetic field along the periphery of the weld path at spatially different locations of the periphery, for example by a varying degree of excitation of individual radial magnets forming the magnet system, was used to counteract non-uniform material and heat distribution during welding.
