Abstract: A system for joining partitioning panels is simple to assemble and take down while effectively concealing the inter-panel connections and maintaining visual continuity of the panels. Attachment fittings are provided at the top and bottom corners of each panel and plate-like connector brackets are used to connect the fittings and assemble the panels either in line or at an angle. Snap-on covers are provided for the top attachment fittings which conceal the connector brackets and form a visual continuation of finishing strips which extend along the top edges of the panels.

Abstract: A welding machine lays down its welding bead at the juncture of two surfaces, back of which a pressure boundary has been formed. A depression, or groove, is provided at the juncture of the two surfaces. The weld bead bridges over the groove to form a junction of the two surfaces, leaving the bottom of the groove above the pressure boundary to function as a passage for materials at the surfaces which vaporize at the temperature of the welding operation. The escape of the gases through the passage obviates the gases bubbling up through, and deteriorating, the solidifying weld material forming the junction.
