Description

Technical Field

[0001] The invention relates to the technical field of welding block spraying, and in particular to a protective paint spraying device and method for welding blocks. Background Art

[0002] Welding blocks are widely used in many fields such as machinery manufacturing, automobile industry, building structures, etc. In these industries, welding blocks are key components for connecting different parts, and their quality directly affects the stability and safety of the entire structure. For example, in automobile body manufacturing, welding blocks connect various parts of the frame together and bear various stresses during vehicle driving. However, welding blocks are susceptible to corrosion. Since they are usually made of metal, in a humid environment with corrosive gases, the metal on the surface of the welding block will react chemically with the surrounding medium. For example, in a seaside environment, the salt in seawater can easily cause the welding block to rust, resulting in a decrease in its mechanical properties and shortening its service life.
