Description

Technical Field

[0001] This utility model belongs to the field of clamping and positioning tooling technology, specifically a clamping and positioning tooling for testing marine titanium alloy welded joints. Background Technology

[0002] To improve seawater corrosion resistance, ship propeller shafts, cooling pipes, and pressure hulls are typically made of titanium alloy. However, cooling pipes are not easily integrally formed, so they are often connected by multi-section welding. The strength of these connections determines their stability and service life. Therefore, during processing, welding strength tests are usually conducted. These tests require clamping and positioning fixtures to hold and fix the pipes. However, existing clamping and positioning fixtures typically only provide partial clamping, such as a three-jaw chuck. This method can easily cause localized deformation of the pipes under stress, affecting the test results. Therefore, this application proposes a clamping and positioning fixture for testing ship titanium alloy welded joints to achieve a wrap-around clamping and positioning of the pipes, improving clamping stability.
