The service life of printing plate needs our careful care, only in this way can it achieve the best use effect. Although the printing board itself has a good corrosion resistance, but the long-term in the alternate wet and dry environment, also corrosion and rust. So we have to maintain the color printing plate is very important.
The steel with poor welding performance is prone to brittle cracks in the heat affected zone of welding, which is not easy to ensure the quality of welding, so the weld joint of printed plate is very important, only by adopting a specific complex welding process. Therefore, for the important welding structure under dynamic load, the welding performance of the steel used should be identified, so that the printing plate can have a longer life and greatly reduce the cost for customers.
