| 摘要 |
FIELD: processes for welding austenite steels. ^ SUBSTANCE: method comprises steps of applying to near-seam zone ultrasonic oscillations in frequency range 22.1 - 22.7 kHz. As melt is degassed and thermal equilibrium is set in crystal lattice, seam metal crystallizes at improved condition that is why welded joints practically have no residual stresses. ^ EFFECT: improved quality of welded joints. ^ 1 dwg |
