Investigation on the Welding of High-Strength Aluminum Alloys,
Abstract
The objective of this program was to develop methods for improving the strengths of joints in high-strength aluminum alloys. Details of the work during the period May 1, 1949, to October 31, 1949, are also presented. The all-weld-metal strength properties and the aging characteristics were determined for welds made between copper dams and in alloy base plates with aluminum-magnesium alloys containing from 5 to 15 per cent magnesium. Transverse tensile tests of joints made in 61S-T6, 24S-T4, and 75S-T6 plates with these alloys were also carried out. Some cold-welding tests were made. The major effort during the third contract period was devoted to testing two series of aluminum-alloy filler metals. One of these series was based on the Frontier 40E composition (5.5% Zn, 0.5% Mg, 0.2% Ti, 0.5% Cr), the other was a series of aluminum-magnesium alloys covering the range from 5 to 15 per cent magnesium.
