The most widely accepted method of measuring the material ductility factor of aztm to lamellar tearing is the reduction of area of a round tension test specimen oriented perpendicular to the rolled surface of a plate. Last previous edition approved in as A — 86 A Test Methods and De? Tensile Strength Requirements S1.

It is generally caused by strain induced in the thickness direction resulting from shrinkage of the weld deposit and by the restraint imposed by the components that comprise the weldment. A minimum slenderness ratio of 2 was selected for the standard Type 2 specimen asmt allow a 0.
Below this minimum value, the x770 at the failure point in the reduced section is restrained by the larger cross section away from the reduced section.
Shielded metal arc, friction, stud, or electron-beam welding methods have proven to be suitable.

For plates over 41? The principal purpose of the testing is to provide a measure of the resistance of a steel plate to lamellar tearing.
