  • Influence of laser pulse shape on welding of quench - hardened steel [Elektronski vir]
    Tušek, Janez, 1952- ...
    The paper treats the application of laser to repair of damaged cold - work tools occurring during operations. The first part describes a suitable laser unit enabling crack grooving and then welding. ... An NdČZAG laser source is shownwith its equipment for laser-beam transfer, control and directing of laser-beam focus. In the third part the different shapes of laser pulse are described. The next part includes the effect of the various pulse shapes on the solidification and microstructure behavior and defect formation of a cold work tool steel after surface remelting and cladding with wire bz a pulsed Nd:YAG laser.
