Title: Innovations of James E Alleman in Welding Technology
Introduction
James E Alleman is a notable inventor based in Houston, Texas, recognized for his contributions to welding technology. With a total of two patents to his name, Alleman's work has significantly advanced the field of pipe welding. His innovative designs focus on improving the efficiency and effectiveness of welding processes.
Latest Patents
Among his latest patents, Alleman has developed an arc welding pipe apparatus and a pipe welding clamp apparatus. The pipe welding clamp apparatus features a pair of clamp assemblies, one of conventional design and the other of a special design that allows access to the axial space between the clamp assemblies. This design enables the placement of internal welding assemblies within the axial space and at a location opposite the special clamp assembly. Each welding assembly is equipped with a large welding electrode reel and an electrode feeder, which communicates with a torch assembly through a flexible tube. The torch assembly includes mechanisms for angular and radial position adjustments, as well as novel means for oscillating the torch to create a wider root weld. This innovation addresses challenges such as torch position misalignment and irregularities in pipe alignment and welding gap width.
Additionally, Alleman's improved methods and apparatus for welding involve oscillating the welding electrode laterally of the weld path. The correlation between the welding current pulse frequency and the oscillation frequency allows for controlled deposition of weld metal droplets at each side of the weld path. An electrical circuit manages the oscillation frequency and the welding current pulse frequency, ensuring precise control over the number of weld metal droplets deposited during each oscillation.
