Automatic Rockwell Hardness Testing

October 1, 2007
A Rockwell hardness tester for automatically performing hardness traverse sequences on larger and unmounted test samples is available. An advantage of the Rockwell test compared to other test methods is that the system has less mounting and less surface preparation requirements than systems using other test methods for traverses in applications such as weld testing or effective case depth measurement. The system uses a Versitron Rockwell tester to make the indentations. The Versitron can test samples that may deflect or settle slightly when test loads are applied, thereby eliminating the need for special fixturing on a wide range of test samples. The system enables applications such as dual traverses for welding or staggered test traverses for shallower effective case depth testing. A computer is used to display the video input for positioning, initiate the testing and control the test positioning through motorized X/Y tables. User-controlled setup files can handle an unlimited number of test sequences.
