An inflatable packer or bridge plug utilized in well bores comprises a tubular elastomeric bladder that is circumferentially surrounded by flexible metallic rib elements. At opposite ends of the packer, the ribs are secured to the inside bore of respective end sleeves by welding and by non-welded bonding. The rib ends are corner bead welded to the end sleeve bore wall to overlie a circumferential undercut of the sleeve bore wall. A second, circumferential weld bead fuses an adjacent sleeve ring to the first and integrates peripheral elements of the ribs. One or more radial vents into the undercut facilitates distribution of a low temperature bonding compound such as epoxy or polyester resins or braze metal or solder. The welding procedures are carried to completion before the bonding agents are applied.
