【 摘 要 】
DP450 dual phase steel has attracted an increasing attention as a material with commercial value for certain applications in automotive industry, nowadays. The purpose of this study was to investigate microstructure, micro-hardness, tensile shear tests, and corrosion properties of DP450 dual phase steel sheet welded using spot welding under both uncoated and hot dip galvanised conditions. Experimental results concluded that there was an increase in joining strength with an increase in welding current and weld time; and welding parameters did not have any significant effect on corrosion properties. The uncoated specimens had more corrosion resistance in comparison to the hot dip galvanized specimens.
