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 40 μm 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.
