    Abstract: A method of brazing aluminium parts with a solder of a melting point of 500-630.degree. C. and a flux of a melting point of 550-500.degree. C., the brazing being made by successively heating them at a comparatively low temperature of 580-660.degree. C. under an inert gas atmosphere filled in an elongated muffle which is made of carbon, graphite or carbon fibre-reinforced carbon, wherein the muffle which contributes to keep the atmosphere at a high purity shall not be damaged by the flux liquidized with the heating of the parts, and wherein carbon of the muffle works to keep the atmosphere inert whereby the flux itself is also prevented from oxidation.

    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.

    Abstract: A pipe cutting machine capable of cutting saddles and mitres and combinations of saddles and mitres is disclosed. The machine uses the rotation of the pipe itself to power a cam drive assembly. The cam drive assembly powers a saddle cam and a mitre cam. The saddle cam and the mitre cam may be set such that a specific mitre cut, saddle cut, or combination of saddle and mitre cut may be accomplished. A cable assembly translates the rotation of the saddle and mitre cams to a torch carriage. The torch carriage in turn translates its movement concurrently to the torch itself, thereby cutting the exact saddle, mitre, or combination of saddle and mitre cut desired.
