- •
Laser welding characteristics of new GH3535 alloy of TMSR was studied.
- •
Comparative study of laser welding in continuous and pulsed waves
- •
Porosity rate and molten dynamics at both cases were investigated.
- •
Pulsed welding produced finer microstructure and more precipitated particles.
- •
Superalloy welded joints at room and high temperature were evaluated.
