Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, and more specifically to a test plate assembly device for welding experiments. Background Technology

[0002] Currently, in welding experiments conducted to determine welding process parameters, process engineers use standard welding test plates with varying lengths and widths (300mm and 150mm, with varying thicknesses). There is a lack of suitable equipment for pre-welding assembly of test plates at different angles and welding positions to simulate actual product weld joints. Process engineers often only roughly estimate the angles before conducting experiments, leading to inaccurate simulations and deviations in the process parameters obtained. These parameters may not be applicable to actual product welding, resulting in welding defects and affecting product quality.

[0003] Therefore, to meet practical needs, a test plate assembly device for welding experiments is provided. Summary of the Invention

This device ensures high-precision assembly and positioning of the test plate before welding through mechanical means, and achieves consistency between the welding simulation test plate and the actual structure through multi-directional and multi-fastening devices, thereby ensuring welding quality. The adjustment process is also simple to operate.
