What is Welding Fabrication Structural Parts


Welded structural parts refer to common metal structures suitable for fabrication by welding. Due to the wide variety of welded structural parts, their classification methods are also different. For example, according to the manufacturing method of semi-finished products, it can be divided into plate welding structure, punching welding structure, etc.; according to the structural use, it can be divided into vehicle structure, hull structure, aircraft structure, etc.; according to the material thickness of welded parts, it can be divided into thin-wall structure and rear wall structure Structure; according to the type of weldment material, it can be divided into steel structure, aluminum structure, titanium structure, etc. and related books.


What are the types of welded structural parts

There are many types of welded structural parts, and the production processes and requirements are also different. The corresponding welding fixtures and displacement machines are also very different in form, working principle and technical requirements. With the expansion of the application range of welded structural parts and the improvement of the level of mechanization and automation of welding production, the types of auxiliary mechanical equipment such as fixtures and displacement machines used in the production of welded structural parts will also continue to increase. According to the use of these auxiliary mechanical equipment or welding process equipment, it can be divided into four categories: welding fixture, welding displacement machinery, welding process combination machinery, and welding auxiliary equipment. The jig used for assembling and positioning the workpiece is called a jig; the jig used for welding the workpiece is called a welding jig, and the jig used for assembling and welding is called an assembly welding jig. They are collectively called welding fixtures. Welding fixtures are divided into six categories according to the power source: manual fixtures, pneumatic fixtures, hydraulic fixtures, magnetic fixtures, vacuum fixtures, and electric fixtures.

What are the main materials of welded structural parts?

The parts of welded structural parts are mostly made of metal rolling materials (sheets and profiles) as blanks, and a small amount of castings, forgings and stampings are used as blanks. Most of the latter can be directly welded, except for some processes that require machining, cutting (blanking), edge processing, forming and bending, and bevel cleaning before welding. These processes are essential, and their importance lies in the fact that the quality of material processing will directly or indirectly affect product quality and production efficiency.


The workload of metal material processing occupies a considerable proportion in welding production. For example, in heavy machinery welding structural parts, it accounts for about 25% to 60% of all processing hours. Therefore, improving the mechanization level of material processing technology and adopting advanced processing methods play an important role in improving processing quality and labor productivity.
