PARTIAL-PENETRATION WELDED CONNECTIONS FOR ALUMINUM COMPRESSION MEMBERS,
Abstract
For aluminum compression members or shell structures that cannot conveniently be heat-treated after welding, partialpenetration welding retains much of the original compressive strength of the structure and is a potentially useful idea for the design of deep-submergence vehicles. Three sets of 1 by 2 by 6-inch 6061-T6 aluminum short columns were butt welded at mid-length with root penetrations of 1/16, 1/8, and 1/4 inches. Compression tests yielded 97, 80, and 72%, respectively, of the strength of a similar one-piece 6061-T6 aluminum column. Additional tests of columns of various lengths with 1/8-inch penetration welds yielded compressive strengths significantly better than similar columns with fullpenetration welds. The advantage is greatest in columns of short and intermediate length. The partial-penetration welded connections exhibited enough shear and tensile strength for applications in which the loading is primarily compression. (Author)
