Description

Technical Field

[0001] This utility model relates to the field of shipbuilding testing technology, specifically to a device for inspecting the flaring of the weld joint of a ship-grade aluminum frame profile. Background Technology

[0002] In the shipbuilding industry, marine aluminum frame profiles are an indispensable basic material. They possess excellent strength, corrosion resistance, and lightweight properties, and are widely used in the construction of critical components such as decks, bulkheads, and frames. These structures need to withstand enormous pressure, impact, and seawater corrosion, therefore, the quality of marine aluminum frame profiles directly affects the structural safety and service life of the ship. With the continuous development of shipbuilding technology, the quality requirements for marine aluminum frame profiles are becoming increasingly stringent, especially the quality of their fusion welds, which is a key factor affecting the overall performance of the ship.

[0003] However, existing methods for inspecting the flaring joints of marine aluminum frame profiles present numerous problems. Traditional testing methods, such as using an aluminum profile compression testing machine to perform compression tests on the fusion weld, are complex and have many flaws. Before the compression test, the marine aluminum frame profile sample needs to be sawn into four small V-shaped specimens. This method often leads to stress concentration in the upper or lower weld area of ​​the fusion joint, causing grain dislocation slip in the fracture morphology and altering the actual fracture morphology of the fusion joint. Such test results cannot accurately reflect the true quality of the weld, posing a significant challenge to the safety assessment of ship structures. This means that even if the strength or toughness indicators of the weld meet the requirements during testing, the actual performance of the weld may have been affected by the testing method and cannot meet the requirements for use in the actual working environment of the ship. In addition, traditional testing methods also pose certain safety hazards during operation. Both V-cutting and V-groove fixing methods require complex sample processing and fixation, which not only increases the difficulty and cost of operation but also may lead to deviations during sample placement and fixation, resulting in inaccurate and unstable test results. Therefore, developing a dedicated flaring inspection device capable of accurately detecting the quality of the fusion joint of marine-grade aluminum frame profiles is of vital practical significance and application value for improving shipbuilding quality and ensuring safe ship operation.
