How to weld container accessories?

Welding has developed from a variety of processing techniques into a scientifically based welding engineering and welding industry with widespread application scale and prospects. In these industries, welding occupies an important position, which is the crux of determining the safe use of its products. Some of the welding products are directly produced or put into use after welding on site, and some are made into the main structure and then installed with power and electromechanical equipment on it. The structure, material matching, process design, advanced welding manufacturing technology and equipment and correct non-destructive testing techniques of the welded joints determine the internal and external quality of the welded joints, resulting in the spread of various industrial and basic equipment. The welding structure industry with its own characteristics has been established, and the welding equipment industry and welding material industry required for structural welding have also been created. These industries are interconnected and rush industries. Welding structure has been developed in a thousand miles: the use of welding structure to partially or completely replace casting or forging structure in equipment manufacturing industry structure and welding of some castings or forgings into combined structure is the direction of large and heavy structure development. The basic construction investment and power consumption of the forging workshop and its equipment can also prolong the consumption cycle; in various construction industries, steel welded structures are generally used instead of reinforced concrete structures, which can achieve long-span, light weight, factory-made, The design is excellent, the construction period is short, the environmental purification is less, the basic cost is low, and the materials can be recycled after removal, so it is in line with the current trend of green production and resource recycling to build a diligent and thrifty society. At present, the development of my country's microelectronics and IT industries, the application of high-strength non-ferrous metals, optical brazing, superconducting and composite materials and polymer materials, and container accessories have put forward many new requirements for welding processes, equipment and materials, so they have received develop accordingly. In the planning era of welding structure, welding material and welding equipment enterprises, container accessories belonged to various industrial ministries, and they were connected with each other, but foreign metallurgical enterprises had research departments specializing in welding performance and welding strength to study and develop welding. Structural steel, provides users with a full set of materials and matching welding materials, and creates good conditions for users to use. Foreign steel structure enterprises often consume centrifugal ductile iron pipes of various welded structures. Many foreign welding equipment and materials are consumed in one company. For example, British Welding Alloy Co., Ltd. and Lincoln Welding Equipment Co., Ltd. of the United States supply multi-functional combined automatic welding machines and corresponding flux-cored welding wires at the same time. At present, the consumption of welding structures in China also tends to be integrated. For example, bridge factories build gantry cranes, and shipyards and bridge machinery factories also build bridges. However, the industry of welding equipment and materials has not yet been integrated. How to make the welding structure, welding materials and welding equipment market-oriented and informatization as the center to create an industrial chain, interdependent cooperation and cooperation, unique development is an urgent problem to be solved.
