In this research, the effect of shielded metal arc welding (SMAW) process heat input upon microstructure and development heat-affected zone in dissimilar joint API 5L X80/DS5 2205 steels was investigated by recording thermal cycles with thermocouple implantation perpendicular direction weld line. The filler used (electrode) is DSS 2209. base metals their interfaces at different inputs were usin...

The inhibition properties of synthesized imine compounds N,Nʹ-bis(2,4-dihydroxyhydroxybenzaldehyde)-1,3-Propandiimine, N, N′-bis(2,4-dihydroxypropiophenone)-2,2-dimethylpropandiimine, N,Nʹ-bis(2,4-dihydroxyacetophenone)-1,3-Propandiimine has been investigated for API-5L-X65 steel corrosion in hydrochloric acid by scanning electron microscopy, potentiodynamic polarization and impedance spectrosc...
