Overview

Research examines how laser parameters affect weld bead and microhardness in stainless steel tubes, indicating optimal settings for quality.

Key Points

  • The study aims to investigate the effects of laser parameters on the microstructures and mechanical properties of laser-cladded stainless steel tubes.
  • Performed high-speed laser cladding using 1Cr17Ni2 powder on 1Cr17Ni5 stainless steel tubes
  • Investigated effects of variables like powder feeding rate, laser power, and protective gas flow rate
  • Analyzed microstructures and microhardness of the cladding layer after multi-pass cladding
  • Laser power significantly increased weld bead width with higher power
  • Powder feeding rate greatly influenced weld bead height and penetration depth
  • Microhardness of the cladding layer decreased from 562 HV to 532 HV with increasing distance from fusion line
  • Primary austenite columnar crystals found with martensite in the microstructure
