Abstract:

SHEAR TEST VALUES OF ALL THE GAUGES EXCEEDED THE MINIMUM REQUIREMENTS OF THE SPECIFICATION. A comparison of these val ss with the shear strength values of the 17-7PH certification showed the 0.025- to 0.025-in. spotwelds to be slightl lower than those of the certification. The 0.025- to 0.040- and 0.040- to 0.040-in. gage spotwelds well exceeded ee shear strength results recorded on the 17-7PH certification for the same gauges. The penetration of the spot weld macro-specimens of each gage were well within the required range of the specification. Nugget diameters of all three groups were within the maximum and minimum diameter size require ments of the specification. Author
