A pair of semcircular jaws seal against the outer periphery of a pipe adjacent a butt weld joint in the pipe. The jaws have annular pressure rims that apply mechanical pressure against the outer surface of the pipe; and the jaws provide an annular manifold cavity between the pressure rims through which high gas pressure is applied against the joint and adjacent areas of the pipe, all for the purpose of slightly deforming the pipe and opening up any fissure that may exist by reason of an imperfect joint. In a modified form, a cylindrical shroud carries an annulus of balls for supporting against and applying deforming pressure on side portions of the pipe as the shroud is rotated around the pipe.

Weld test tool

A package for storing and transporting a single wafer of silicon or the like which may be 300 millimeters or more in diameter. The package has a U-shaped frame with a ledge on it for supporting the edge of a wafer, the open side of the U-shaped frame permitting insertion and removal of a wafer; a top panel affixed to the U-shaped frame and traversing the U-shaped frame defining a wafer compartment with the frame, and confining the wafer therein; a retainer traversing the open side of the compartment to obstruct removal of the wafer; wafer clamping devices confronting the ledge to clamp the edge portion of a wafer thereon; an access slot through the ledge portion of the frame to obtain access to the edge of the wafer for lifting it; the entire frame portion being open in a downward direction as to open the lower side of the wafer compartment to allow obtaining access to the wafer; the frame also having stacking ribs and grooves; a robot handle on the top panel and an adjacent operator for the retainer to also be operated by a robot.
