INVESTIGATION OF ALUMINUM ALLOY 6061 T4-T6 WELDED AND UNWELDED
BELL AEROSYSTEMS CO BUFFALO NY
Pagination or Media Count:
Aluminum alloy 6061 was studied from practical welding considerations. Effort was made to duplicate in-shop welding and heat treatment conditions. Areas of concern to the design and metallurgical engineering departments in regard to tank fabrication, including mismatch due to improper line up of various degrees 25, 50 and 100, effect of weld repairs, hand versus machine, effect of aging, and the effect of low temperatures on the mechanical properties of welded and unwelded, notched and unnotched, solution treated and solution treated and aged material, were studied. Mismatch is encountered in hardware fabrication as the result of poor line up or warpage of one piece of material in respect to another prior to welding. The designer is in need of this information to arrive at sound engineering safety factors.
