Results of tests show that a slowly rising condenser-discharge preheat current with a rapidly rising welding current afford no less expulsion than a rapidly rising welding current alone, and was inferior to a slowly rising welding current alone. In one case using slowly rising current for preheating and welding proved beneficial although generally, utilizing a raised electrode welding force to decrease expulsion was more practicable. Postheating had no effect on sheart strength until the current sufficient to remelt the welds, which greatly increased the weld diameter and shear strength.

Results are present for part of a test program on 24S-T aluminum-alloy flat compression panels with hat-section stiffeners. The results show the effect of the relative dimensions of a panel on the buckling stress and average stress at maximum load. Comparative envelope curves are presented to provide some indication of the relative structural efficiencies of hat- and Z-stiffened panels having a ratio of stiffener thicknews to skin thickness of one.

Mechanical And Corrosion Tests Of Spot Welded Aluminum Alloys written by Fred M. Reinhart and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1951 with Aluminum alloys categories.
Corrosion behaviro of spot-welded aluminum-alloy (alclad 24S-T3, 24S-T3, alclade XB75S-T6, XB75S-T6, and R-301-T6) panels of varying weld quality was determined. Tidewater and weather exposure tests were made and the results were evaluated largely in terms of distribution of corrosion products and effects on weld strength. Metallographic examinations of several of the alloys were also made to determine the extent and type of corrosion attack associated with various welding and exposure conditions.
