Our Lab. aims to Elucidate Metallurgical Phenomena during Welding
based on Materials Science & Engineering
and to develop innovative welding & joining technique.

  • Elucidation of mehcanism of microsturucural evolution (solidification, phase transformation etc.) during welding & joining
  • Elucidation of infuluencing factors on defect formation (hot, reheat & cold cracking) and the mechanical properties of weldments
  • Development of technique for property modification and reliability evaluation by innovative method of microstructure control
