Manufacturing is the foundation of national strength, please pay attention to “metal processing” (mw1950pub).

Technical features: 1. A method for stress relief of a large welded structural member, the large welded structural member (1) comprising a first plate member (11) and a second plate member (12) which are welded and fixed

The main girder structure of overhead travelling crane will be deformed by various factors in the process of long-term application, and the deformation problem can not be completely avoided, for the deformation of the main girder structure.

China chemical machinery and equipment network collation: impact crusher is a new type of rate of crushing equipment, which is characterised by: small size, simple structure, large crushing ratio, consumption of

Winding hoist main drum welding treatment Abstract: the hoist in the process of long-term use, due to fatigue caused by the drum wheel and internal support plate welded analysis, and the use of reasonable ways to strengthen the use of the drum can be normal and safe use.

Corner welds are a common feature in steel structure welding, and their diversity and complexity present welders with considerable challenges. Behind the various types of corner welds lie specific standards and requirements. So, how can corner welds be completed efficiently and accurately to meet engineering requirements?

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

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.
