CURTAIN FOR SHROUDING WELDING OPERATIONS

摘要

A curtain for surrounding welding and cutting operations, especially electric arc welding and electric arc cutting operations to protect the eyes of otherwise unprotected observers. The curtain has discontinuities distributed throughout. The discontinuities have an optical index of refraction that differs from that of the primary curtain material by at least 0.2 units. This scatters the light passing through the curtain and reduces the exposure of the retina to undesirable light intensities.
