Defect Repair Technology Of Precision Marble Testing Platform

- Jun 22, 2017 -

Precision Marble Testing Platform The effect of scraping depth on the service life of vibration experimental platform is not negligible. There is no doubt that the verification procedure does not provide for the depth of the scrape. From the point of view of use, without causing the workpiece and the vibration of the platform platform for granite to develop.

The thermal stress is larger, which is more prone to crack than arc welding, and the tendency of line shrinkage to crack is greater. Because the crack inclination is influenced by the spraying time and the thickness of the spray layer, the defect size is limited, and the defects of welding and mending need to be cleaned up, because the proportion of FE in the dusting is higher.

The formed spray layer is more similar to the color of the base metal than the arc welding. However, because of a certain amount of NI, it can not be closer to the color of the Masterbatch, welding after the mechanical processing. Traditional spray welding, arc welding technology, welding and repair easy to produce cracks, workpiece easily heated deformation.

Increasing the contact area as much as possible can improve the service life of the vibration experimental platform. This is not properly restricted by the verification procedure. In order to improve the service life of the platform and ensure its working accuracy, it is suggested that the depth of scraping or the control in 0.02mm above, this can ensure that the vibration test platform has a longer service life and verification cycle.

According to the spray welding process execution, the guideway surface preheating to 150 Shan above, finish the initial welding powder spraying, will be sprayed with warm to 900 above.

The welding powder is melted to form a flat surface. Because the granite platform is warm and the heating time is long, the workpiece heating area is larger.

Easy to appear two times stomata, weld the metal color and the mother material difference is its common characteristic, this is also the traditional welding repair technology can not completely solve the machine tool guideway flaw repair the basic reason.
