Abstract
A fold along the exterior of a container body between the rim of the latter and a sheet metal closure member forming the top or bottom of the container defines a crevice between material of the closure member and the container body adjacent the latter. A laser beam is directed in this crevice and the container and beam are relatively rotated to form a continuous weld in the crevice so that reflection of laser energy from the weld site is avoided.
