Technical Brief: This patent proposes an automatic turning device for the problem of low efficiency and high safety risk caused by traditional plate turning relying on manual or travelling vehicle operation. The 180°turning of the workpiece is realised by the rotating structure of the clamping part and the longitudinal beam, together with the design of the limit device and concave table.

The heat-affected zone is the region where the microstructure and mechanical properties of the material change due to the effects of heat (without melting) during the welding process. The microstructure and properties of the weld metal resulting from recrystallisation are related to the chemical composition of the weld, the cooling rate, and the post-weld heat treatment.

Welding defects: How to avoid weld failures due to “dissolution” problems? When a welded joint fails, often the problem is not in the material itself, but in the microscopic “dissolution” process. Understanding and controlling dissolution is the key to eliminating common weld defects and improving product yields...

01 Overview of assembled steel structure nodes China has promoted the development of assembled buildings in recent years, and the assembled connection nodes of square steel tube columns and beams have gradually become a research hotspot because of their high efficiency and environmental advantages. Assembled steel structure is different from traditional building structure, it is prefabricated in the factory.

Vibrating screen side plate cracking is not to be afraid of, a few simple steps can be easily fixed! (With specific processing steps) Vibrating screen is easy to appear after a long period of operation, such as cross beams, track beams and other fracture and side plate cracks and other problems, cross beams and track beams can be solved by replacing, and the side plate out of the
