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. Final assembly includes the steps of sliding an overlying sleeve over the end fitting, the weld and a portion of the slats and engaging threads on the interior of the sleeve with external threads on the end fitting. The sleeve can thereby be unaffected by the heat treatment steps.
