Optimization of Equipment and Techniques for Welding Aluminum in the Thickness Range of About 1/16 to 1/4 Inch
Abstract
The laboratory phase of this contract fabricated fillet welded panels, using gas metal arc welding (GMAW), pulsed GMAW, high-frequency resistance welding, explosion welding, and electron beam weldtrusion (inchamber) . Butt weld investigations included conventional GMAW, plasma GMAW, and sliding seal electron beam (out of chamber). For conventional GMAW welding, power sources, shielding gas mixtures, and travel speeds were evaluated for their effect on panel distortion, joint soundness and strength. All of the specimens were evaluated for static and fatigue strength, corrosion fatigue, corrosion resistance, hardness, residual stress, shrinkage, heat input and distortion. The contract analyzes the results of fabrication and evaluation of the fabricated specimens, along with equipment costs and economics to attempt to determine the optimum weld process for various types of ship construction.
