Conclusions

  1. 1.

    Forced cooling of the weld pool by means of a water-cooled copper roller increases the solidification rate for or five times.

     
  2. 2.

    A high solidification rate of the weld pool leads to reduction of the grain size or primary β phase and refining of the intragranular α′ phase. No precipitation of phases inducing embrittlement of these alloys occurs in the grain boundaries.

     
  3. 3.

    With forced cooling of the weld pool by means of a roller the hardness of the weld metal hardly differs from that of the base metal. Weldments in alloy OT4 are characterized by high ductility and toughness, and the number of cycles to failure in fatigue tests is highest.
