Residual Stress Measurements on M1 Tank Weldments
Abstract
Residual stress levels were measured on four weldment areas of the M1 tank--two on the hull and two on the turret. Measurements were performed on preexisting tanks as well as on current production runs. Two hulls and two turrets of preexisting tanks were measured; three hulls and two turrets of current production runs were measured. Measurements were performed on the weld nugget and heat-affected zones using portable X-ray diffraction equipment. A total of 142 measurements were performed. Only six measurements exhibited tensile residual stresses; the remainder exhibited compressive residual stresses. The highest tensile residual stress observed was 47,000 psi. Weldment areas measured were: race ring to forward glacis; turret roof plate joint; gunner primary sight to frontal slope plate; and side plate to front portion of hull.
