The basic concept of the galvanized steel

Galvanized steel refers to ordinary carbon construction steel, which can effectively prevent steel corrosion and rust, so as to prolong the service life of steel, including electro galvanizing and hot-dip galvanizing

Galvanized steel generally used for building exterior walls, such as glass curtain wall, marble curtain wall and aluminum curtain wall as columns and stress-bearing materials, or for outdoor telecommunications towers, highways and other open-air buildings, steel is called galvanized steel, in which galvanizing is divided into electro galvanizing and hot-dip galvanizing.

(galvanized steel)Cracks, pores or softening structures are easy to appear in the nugget. In the process of spot welding of galvanized steel sheet, due to unreasonable welding specifications, small cracks or pores may be formed in the residual part of zinc and zinc iron alloy in the joint during nugget crystallization, and softening structure will be formed when there is more residual zinc Ways to improve spot welding quality of galvanized steel sheet.
