Description

Technical Field

[0001] The utility model relates to the technical field of ship thin plate welding, in particular to a ship thin plate welding deformation detection device. Background Art

[0002] As an important joining process, welding process is widely used in manufacturing industry. The uneven heating in welding process leads to welding deformation and welding residual stress, which causes various welding deformations in the structure, including transverse and longitudinal shrinkage deformation, angular deformation, bending deformation, wave deformation and twisting deformation. The existence of welding deformation not only causes the shape variation of welding structure, the decrease of dimensional accuracy and the reduction of bearing capacity, but also the additional bending moment and stress concentration caused by working load are the main reasons for the early failure of welding structure and one of the reasons for the reduction of fatigue strength of welding structure. In the welding process of ship thin plate, welding deformation is an important factor affecting the processing accuracy, external shape and structural performance of welding products, and is an urgent problem to be solved in industrial production. The causes of welding instability deformation are complex, and there are obvious shortcomings and deficiencies in numerical simulation. Theoretical prediction and analysis alone cannot accurately reflect the actual welding deformation.

The ship thin plate welding deformation induction leveling experimental device can control the position of the induction coil in the X-axis, along the weld direction, the Y-axis, in the horizontal plane perpendicular to the weld direction, the Z-axis, and the vertical direction. The moving speed and moving time of the induction coil in the X-axis can be accurately adjusted, and the temperature change of the thin plate during the heating process can be recorded. The induction power supply parameters can be adjusted in real time based on the results of the infrared thermometer. However, the ship thin plate welding deformation induction leveling experimental device cannot quickly disassemble and assemble the ship thin plate, which reduces the efficiency of ship thin plate welding and does not meet the user's use needs. Therefore, a ship thin plate welding deformation detection device is proposed to solve the above problems. Utility Model Content
