1. the welding method of a low-alloy super-strength steel;

  • it is characterized in that;

    to the laser weld of low-alloy super-strength steel;

    laser beam welding refers to;

    with low-alloy super-strength steel bulk material for welding material;

    wlding is preset at surface, district to be welded, adopts laser focusing bundle to be thermal source, direct for welding material melting welding is deposited to district to be welded;

    under argon shield, laser beam scanning is until complete the welding in whole region, is aided with stress annealing process subsequently.
