8mm thickness Al-Zn alloy coated steel sheet spot welding, the impact on the quality of the main welding parameters are welding current.

The surface quality, mechanical performance and corrosion resistance of galvalume products were introduced,such as DX51D,DX52D and S250GD.

As a kind of new type and high quality but low cost material, galvanized aluminium board and its forming characters are introduced.

The commercial hot-dip galvanized sheet steel was investigated for its corrosion behavior in three different seawater zones in Qingdao with electrochemical measurement,weight loss test and SEM.

With the rapid development of Chinese economy, demands for galvanized sheet steels increased significantly because of the rapid development of construction and automotive industry during the last decade.

occured in forming and after coating of the prephosphating galvanized sheet steel,this paper demonstrates analyses on all kinds of influential factors happened in production and forming in detail,after that,provides some solutions on purpose.

Effect of TiC coating on electrode tip surface on electrode degradation during resistance spot welding zinc coated steel;

Effect of zinc coating on arc heating behavior for joining Al and zinc coated steel by welding-brazing process

The effect of TiC coating in electrode tip surface on spheriform electrode degradation during resistance spot welding zinc coated steel was investigated by SEM,EDX and XRD.
