Abstract

The invention provides a metal structure test block for ultrasonic testing. The metal structure test block comprises an inner sand core block, a transition composite layer and an outer metal layer which are sequentially cast. The surface of the inner sand core block is crossedly provided with a plurality of communicated channels. The inner diameter of the channel opening is larger than the widestinner diameter of the channel. The inner sand core block comprises sandstone, soft refractory clay and water glass. The transition composite layer comprises composite molten iron containing silicon carbide. The outer metal layer comprises composite molten iron without silicon carbide. Through the reasonable structure design and material matching, the test block for ultrasonic testing has stable structural quality. The metal structure test block has good internal compactness and retractable elasticity and low transverse wave and longitudinal wave dampening effects, can be used for an ultrasonictest on the diagonal welding joint and has high detection sensitivity.

Description

technical field

[0001] The invention relates to the technical field of metal test blocks, in particular to a metal structure test block for ultrasonic testing and a preparation process thereof. Background technique

[0002] my country's steel structure industry has developed rapidly in the past 10 years, and has become the world's largest steel structure country with the largest steel structure consumption, the strongest manufacturing and construction capabilities, the largest industrial scale, and the largest enterprise scale. The successful construction of major steel structure projects in various places shows that my country's steel structure comprehensive technology level has reached the international advanced level. However, there is still a big gap between my country's steel structure industry and developed countries in terms of informatization, automation, standardization, and scientific research and innovation. Whether it can make my country's steel structure indust...
