    • Abstract
  • 16 MnR steel plate welded by mechanical vibration welding and the one by ordinary SAW has been used to study and analyze the effect on the absorbed-in-fracture energy through impact test.The results show that mechanical vibration welding can increase the absorbed-in-frac-ture energy in weld and HAZ;the increasing percents are related to the frequency and the vibrated force;the effect is more notable when the frequency and amplitude (vibrated force) are choosen appropriately.In this test,the greater the frequency and the vibrated force,the greater the increasing percents of the absorbed-in-fracturc energy.The mechanism of increasing absorbed-in-fracture energy by mechanical vibration welding mainly lies in meehanical vibration making the grains fined and decreasing the sum and size of inclusion.
