Electron Beam Welding of Thick Sections.
Abstract
A brief summarization of the program encompasses: The welding and evaluation of EB welding candidate materials in the 0.5-inch and 2.0-inch thicknesses. Satisfactory welds were accomplished and evaluated in each of the materials. Satisfactory use of the induction method, using water-cooled coils, for materials of large masses requiring preheating and/or postheating. The determination that the surface finish of the abutting edges plays a very small part on the finished weld. Whether a finish of 63 or 1000 rms, or any figure in between, was used the effect on the welds was unnoticeable. The observation that the shape and focal point of the electron beam are not critical from the standpoint of producing high integrity welds on thick section weldments. The conformation that when welding large aircraft landing gear components, large chambers with precise tooling are required, in addition to satisfactory preheating and postheating methods. (Author)
