Abstract: An automatic welding system uses an anti-gravitational welding controller to minimize or eliminate the undercutting and concavity of the roots of the welds caused by gravitational effects. The pressure within the pipes to be welded is continually changed as the welder orbits the pipes. At the upper section of the weld, positive pressure is applied to the pipes to eliminate undercutting at the upper surface of the weld and negative pressure (vacuum) is applied to the lower section of the weld to eliminate concavity of the root of the weld. In one mode, the internal pressure within the pipes is varied as a function of the position of the orbital welder. In another mode, the arc voltage at the tip of the weld, i.e., the distance between the tip of the weld and the surface of the weld, is maintained constant by varying the pressure within the pipes. The system allows for the completion of high quality welds with less weld material, less passes, and less time. It also allows the welding to be performed by welders who are less experienced and skilled as the present welders.

Abstract translation: 自动焊接系统使用反重力焊接控制器来最小化或消除由重力作用引起的焊缝根部的底切和凹陷。 随着焊机绕管道的流动，焊接管内的压力不断变化。 在焊缝的上部，对管道施加正压，以消除焊缝上表面的底切，并向焊缝的下部施加负压（真空）以消除焊缝根部的凹陷。 在一种模式中，管道内的内部压力作为轨道焊接机的位置的函数而变化。 在另一种模式中，通过改变管道内的压力，焊接尖端处的电弧电压，即焊缝尖端与焊缝表面之间的距离保持恒定。 该系统允许用较少的焊接材料，较少的通过和更少的时间完成高质量的焊缝。 它还允许焊接由焊工执行，这些焊工比较少经验和技术熟练，如现在的焊工。

Abstract: A metal brazing sleeve includes a ceramic flux band formed on the sleeve adjacent an annular recess typically disposed near an open end of the sleeve for receiving a conventional braze preform, by adhering a powder flux to the sleeve by a tacky adhesive and then melting the powder flux in place, by internal heating of the tube. The ceramic flux band is hard and adherent, and resistant to abrasion effects during insertion of the sleeve into a tube, and provides a shadow effect for protecting an optional cemented powder flux band which may be formed on the braze ring.

Abstract: A method of arc welding is disclosed. Specifically, a method of pulsed direct current (DC) arc welding is disclosed wherein special pulses of positive direct current are used to weld together work pieces. The special DC pulses are capable of dissipating difficult to reduce oxides which may be present on the surfaces of the work pieces without using a flux. The method is especially useful for fluxless arc welding of aluminum, particularly thin wall aluminum tubing used in making heat exchangers for air conditioning systems.

Abstract: Apparatus for rapid and automatic welding of joints which interconnect sections of pipe, and in particular oil or gas transmission pipe. The system includes at least one torch transport assembly which simultaneously moves a plural number of welding torches along a path parallel to the pipe joint being welded. The torch transport assembly includes track segments which surround circumferential portions of the pipe joint, with a welding torch carrier and multiple torches being independently movable along each track segment. The torch transport assembly is mounted on a support apparatus which is rigidly clamped to the pipe sections during welding, and which permits the torch transport assembly to be rapidly positioned in rough alignment with a pipe joint. The torch transport assembly and selected operating parameters of each welding torch are adjusted to accurately position each torch with respect to the pipe joint, and to repeatably provide programmed welding parameters resulting in a uniform pipe joint weld. The present system is disclosed in the context of hot-wire gas-tungsten arc welding torches, and in the operating environment of out-of-position joint welding.
