Mechanical properties of welds in aluminum alloy 5083 at 4K. Final report
A series of weldments were prepared by five cooperating companies in 51 mm thick 5083-0 aluminum plate using 5183 metal and gas metal arc welding (GMAW) processes. Tensile and notch-tensile properties measured at room temperature and at 4K are similar despite the fact that there were considerable variations in the welding procedures. Fracture toughness and fatigue crack growth rates of the weldments were measured at 4K and found to be similar to base metal properties. Strengths of the welds are appreciably higher at 4K than at room temperature, and notch yield ratios are high, indicating that the welds are tough. Data for each of the mechanical properties do not vary significantly from weld to weld; and it is concluded that the mechanical properties of 5183 welds at 4K do not depend significantly on GMAW parameters and procedures.
