Computerized Profilometer For Inspection Of Welds
Third-generation profilometer for inspection of butt welds includes hand-held probe unit operating in conjunction with computer. Unit positioned across weld, in contact with workpiece, to obtain profile. Increases precision by reducing subjective inputs and concomitant variations in outputs among different operators. Computerization retains capabilities of first- and second-generation profilometers to measure peak angles and mismatches of butt welds and extends measurement capabilities into field of image analysis. Output data more readily processable into forms used by same or another computer.
