Effects of Longitudinal Vibration on Hardness of the Weldments

Abstract

The paper pertains to the effects of longitudinal vibration, frequency and amplitude on hardness of the weldments prepared by metal arc welding under dynamic conditions. The frequency range was 0 to 400 Hz and amplitude range was 0 to 40μm respectively. Investigations show that the hardness of the weldments have increased when compared with the stationary welded test specimens. 0 to 400 Hz frequency range and 5 to 20 μm amplitude range produce good results. © 1993, The Iron and Steel Institute of Japan.
