Generally, as long as the correct methods are used and stored, the service life is long, and the accuracy of the working surface can be maintained for more than 2 years. When the accuracy decreases, it can be restored through debugging or scraping processes. The service life of the flat plate itself can reach 50-100 years. Therefore, during use, it is important to be careful not to use and store it in humid, corrosive, high or low temperature environments, in order to extend the service life and ensure work quality.
To prevent harmful deformation during welding of flat plates, the working surface of the plate should be adjusted to a horizontal plane as much as possible during support. After the inspection or marking is completed, the workpiece should be lifted down and not placed on the flat plate for a long time. After use, the working surface of the flat plate should be wiped clean in a timely manner, and then a layer of rust proof oil should be applied. If not used for a long time, apply a layer of butter and then spread a layer of white paper. A cover made of good wooden boards. When not in use, cover the flat plate with a cover and strictly prohibit water droplets from falling on the welding platform (welding flat plate).
Application of welding flat plate: Used as a basic flat plate for riveting and welding processes, with holes and T-shaped grooves on the working surface. The holes are mainly used to clean some iron slag and welding waste during riveting and welding, while the T-shaped grooves are mainly used to fix the welded parts. Of course, welding flat plates can also be flat, that is, without holes or grooves.
Welding plate material: High strength cast iron HT200-300, with a working face hardness of HB170-240. After two manual treatments (manual annealing at 600-700 degrees or natural aging for 2-3 years), the product has stable accuracy and good wear resistance.
Welding plate specification: 1000x1000—30006000, (Special specifications are made according to the buyer's drawings.)
Welding plate accuracy: According to the standard metrological verification regulations, it is divided into four levels: 1, 2, 3, and precision planing. In general welding work, precision planing welding plates are the main procurement objects
