Beschreibung
Zusammenfassung:	The invention discloses a Christmas tree phased array ultrasonic detection test block which comprises a body, and one side of the body is recessed inwards to form two semicircular arc grooves which are crossed; the upper side and the lower side of the body are connected with a top drift diameter and a bottom drift diameter respectively, the top drift diameter and the bottom drift diameter are both in a semi-arc shape, and the bottom end of the bottom drift diameter is closed. The left side and the right side of the body are connected with a semi-arc-shaped first drift diameter and a cylindrical second drift diameter respectively, the end of the first drift diameter and the end of the second drift diameter are connected with flanges, and the flange connected with the first drift diameter is in a semi-circular ring shape. A plurality of flat-bottom holes and/or a plurality of V-shaped grooves are formed in the groove wall of the semi-arc groove and the inner walls of the first drift diameter, the top drift diam
