How is the performance of Galvanized steel affected

With the development of industry, hot-dip galvanised products have been used in many fields. The advantages of hot-dip galvanising are its longevity and its adaptability to a wide range of environments, which has always been a popular anti-corrosion treatment and is used in a wide variety of fields. In this article we will briefly summarise the properties of Galvanized steel and the factors that influence it.

• The process parameters of Galvanized steel.

What are the factors that affect the quality of Galvanized steel?

The quality of Galvanized steel depends on the chemical composition of the steel such as the silicon content, the cross-sectional area of the steel, the roughness of the steel surface, the density of the Galvanized steel, the temperature of the zinc pan, the zinc dipping time, the speed of cooling and the cold rolling deformation. When selecting Galvanized steel, it all starts with the appearance. The user needs to see if the Galvanized steel is flat and has an aesthetically pleasing appearance. If Galvanized steel does not have a good surface finish, then it is difficult to guarantee its quality.

What are the physical properties of Galvanized steel?

High toughness of the coating

The Galvanized steel layer forms a special metallurgical structure which is able to withstand mechanical damage during the transport and use of Galvanized steel.

Welding properties

Certain types of metal cannot be welded under normal welding conditions due to the increased mechanical properties, the high density of the inner base material surface coating and the relatively high manganese content. Galvanized steel, on the other hand, has good welding properties and in terms of welding hot-dip Galvanized steel performs better and does not have welding problems.

Reliability

Galvanized steel is quicker to galvanise than other coating methods and avoids the time required for painting on site after installation.

Galvanized steel has many advantages, as the galvanising process prevents the surface layer of thick steel from being exposed to air oxidation or liquid leaching, which increases the service life of the sheet and saves a lot of labour for maintenance. Galvanized steel has been widely used in the construction, household appliances, automotive, container manufacturing and electromechanical industries, and has a good future.

The process parameters of Galvanized steel

Due to the small range of welding parameters for Galvanized steel, strict control is required and adjustments are also necessary when the plate thickness changes. The use of reasonable electrode materials, electrode shapes and sizes, and timely trimming or replacement of electrodes and good cooling of the electrodes are important to ensure the quality of the weld. The quality of spot welding of Galvanized steel sheets is assessed in terms of the strength of individual joints, the level of corrosion resistance and, more importantly, the pass rate of joints under large production conditions. A considerable number of factors influence the quality of the weld in practical production, such as fluctuations in the network voltage, shunting, wear of the electrode, and the quality of the assembly. At the same time, we need to choose the right welding method.
