Abstract
The strength of slats attached to an inflatable packer assembly by welding is increased by forming the slats of an age-hardening materials, welding the slats to the inflatable packer assembly in an annealed condition followed by age-hardening of the welded slats. A slat structure having much greater strength than welded cold-worked material is realized.
