Abstract: An apparatus and method for resistance welding tubular parts is disclosed. The apparatus includes a weld gun having displaceable electrodes with contact faces engaging the parts. The contact faces are designed to distribute the forces applied to the parts by the electrodes to prevent deformation and to hold the parts together steadily in order to minimize undesired electrode displacement. A test computer monitors the amount of electrode displacement occurring as a result of penetration of the parts into each other during welding. When the displacement between the electrodes falls within a predetermined displacement range, which is indicative of a proper weld between the parts, the computer cooperates with a weld controller to terminate the welding power, thereby inhibiting any substantial further penetration of the parts. The apparatus and method is suitable for tube-to-tube and wire-to-tube applications commonly performed in the manufacture of automobile seats.

Abstract: A clamping apparatus for use in clamping a fitting to a pipe or other fitting. The apparatus may be used without supporting the outer surface of the pipe on the opposite side of the fitting, and in the case of a buried pipe, only a portion of the pipe needs to be excavated. The apparatus comprises a clamping plate for engaging an outer surface of the fitting with an adjusting stem threadingly engaged with the clamping plate. A locking bar is pivotally and rotatably attached to an end of the adjusting stem. A weight differential between long and short ends of said locking bar and a cable are used to pivot the locking bar between a first position thereof wherein the locking bar and a portion of the stem may be inserted through aligned openings in the fitting and pipe and a second position. In the second position, the clamping bar may be clampingly engaged with an inner surface of the pipe by rotation of the adjusting stem which also results in the clamping plate being clampingly engaged with an outer surface of the fitting. A lock nut locks the apparatus in the clamping position. The fitting may then be permanently attached to the pipe, such as by an electrofusion process, after which the apparatus may be unclamped and removed. A method of attaching a fitting to a pipe using the apparatus is also disclosed.

Abstract: A process for preparing tubular coupons formed of a pair of tube lengths butt-welded together with a full depth circumferential weld includes partially diagonally cutting the coupon sample through its transverse dimension so as to leave a thin bending strip along one wall of the coupon about which the coupon is bent for inspection of the internal surface of the weld area. Two procedures are described, both of which leave the interior surface of the weld exposed adjacent the diagonal cutting line through the coupon. The procedure facilitates bending open the cut coupon for internal inspection of the weld area. A jig fixture for holding the coupon during cutting by a band saw blade is described.

Abstract: Improved welding method and padeye processing speeds up the connection of individual joints by peripheral fusion welding while the joint to be added stands vertically atop an existing pipe string also standing vertical in the rig floor. A plurality of welders can operate to speed up completion of the weld by removing heat from the pipe during the welding process. Heat is removed by the use of fluid cuffs near the weld area and, optionally, by using a spool within the pipe string to dispense expansion cooled air against the inner pipe wall in the vicinity of the weld. A special improved padeye is provided for welding near the pipe ends for handling. The padeye has a divided profile, a hole for a lifting shackle, and it will be accepted within the skirt of the lead system of the driving hammer. The upper end of the padeye can be cut from the pipe while the pipe is resting, on rig related structure, on the lower surface of the padeye.
