Abstract

Power cable of an AC arc welder can surround a body of worker at the moment of welding. Applying the boundary element method, we calculated current densities induced in organs inside a worker in case he weared a multi-layer shielding cloth. We know these were lowest when high permeability materials such as silicon and permalloy were applied to the interior of a suit and high conductivity materials such as copper were to the exterior.
