[0017] The technical solutions in the embodiments of the device will be clearly and completely described below with reference to the drawings in the embodiments of the device, and obviously, the described embodiments are only part of the embodiments of the device, rather than all the embodiments of the device.

[0018] REFERENCE Figure 1The utility model provides a workpiece welding penetration detection device, including test platform 1, be installed above test platform 1 with the hanger rail 6, the hanger rail 6 is installed with the translation component that can move along its length direction, the translation component is installed with the clamp 16 that can fix workpiece, test platform 1 is sequentially arranged cutting station 2, polishing station 3, chemical reaction station 4, microscope observation station 5 along the length direction of hanger rail 6, cutting station 2 can cut workpiece along horizontal plane, polishing station 3 can polish workpiece cutting surface along horizontal plane, chemical reaction station 4 can carry out chemical soaking to workpiece, and microscope observation station 5 can observe workpiece cutting surface from below to above.

[0019] When the device detects welding penetration, the workpiece is fixed on the clamp 16, the workpiece on the clamp 16 is moved in one direction by the translation component, when passing through the cutting station 2, the workpiece is cut off along the horizontal plane, so that the welding part is exposed, then the workpiece cutting surface is polished by the polishing station 3, so that the workpiece cutting surface is further exposed, the clamp 16 is continuously moved, so that the workpiece moves to the chemical reaction station 4 to chemically soak the cutting surface of the workpiece, after soaking, the clamp 16 is continuously moved, so that the workpiece moves to the microscope observation station 5 to observe the welding penetration exposed by the workpiece cutting surface.

[0020] The device only needs to fix the workpiece on the clamp 16, and then move the clamp 16 in one direction, since the workpiece cutting surface is always downward, there is no need to adjust the angle of the workpiece, and the cutting, polishing, chemical soaking and microscopic observation of the workpiece can be completed in one direction, which reduces the detection difficulty and operation complexity, and improves the safety during detection.

[0021] As an embodiment, the cutting station 2 includes a cutting blade 17 with a vertical axis, the cutting blade 17 is drivingly connected to a rotary power source, and the cutting blade 17 is rotated by the rotary power source, when the workpiece passes through the cutting blade 17, the workpiece is cut off along the horizontal direction, so that the welding surface is exposed.

The mixture of nitric acid and alcohol has a strong corrosive effect, capable of removing the oxide layer and impurities from the weld surface, exposing the true structure of the metal substrate and weld metal. The corrosion rate of the corrosion solution varies for different metals, and the structural differences between the weld area and the base metal will become apparent after corrosion. Especially in the heat-affected zone of the weld joint and the transition area of ​​the base metal, corrosion can reveal the grains in these areas.
