Before welding begins, the cylinder and legs of the air-conditioning compressor need to be carefully prepared. As the main load-bearing component of the compressor, the cylinder has extremely high requirements for material and dimensional accuracy. It is usually made of high-quality metal materials to ensure that it can withstand the high pressure and high load when the compressor is working. The legs play the role of supporting and fixing the cylinder, and their shape and size must perfectly match the cylinder. Before welding, the welding parts of the cylinder and the legs should be cleaned, polished and other pre-treatments should be carried out to remove impurities such as oil, oxides and other impurities on the surface to ensure the quality and strength of the welding.

In the welding process, the use of advanced welding technology and equipment is the key. Common welding methods include arc welding and laser welding. Arc welding has the advantages of low welding cost and strong adaptability. By accurately controlling the welding current, voltage and welding speed, it can achieve good weld formation and welding strength. Laser welding, with its high precision, high energy density and small heat-affected zone, can ensure the welding quality while minimizing the impact on the material properties of the cylinder and the legs. During the welding process, it is necessary to strictly control the welding parameters to ensure the uniformity, sealing and strength of the weld. At the same time, in order to prevent welding deformation, appropriate fixtures will be used to fix and position the cylinder and the legs.

After welding is completed, it does not mean the end of the work, and strict quality inspection is still required. Through non-destructive testing technology, such as ultrasonic testing and radiographic testing, the internal quality inspection of the weld is carried out to check whether there are defects such as pores and cracks. At the same time, the appearance inspection of the welded cylinder support assembly is carried out to ensure that the weld surface is smooth and defect-free, and the size meets the design requirements. Only products that have passed strict testing can enter the next process of assembly and debugging.

Every link of the air conditioning compressor cylinder support welding process is closely connected, requiring a high level of technology and strict quality control. Only in this way can we produce high-quality compressor barrel support components, provide solid guarantee for the stable operation of air-conditioning compressors, and bring users efficient and reliable air-conditioning and refrigeration experience.
