Compression testing revealed enhanced mechanical properties in TA2/Q235 cladded pipe, suggesting optimal welding parameters.
In the present study, a TA2/Q235 cladded pipe has been successfully fabricated by using explosive welding. The microstructure at the cladding interface was investigated using optical and electron microscopy-based techniques, which revealed a distinctive wavy bonding morphology at the TA2/Q235 interface. The presence of detrimental intermetallic compounds such as FeTi or Fe 2 Ti was not observed at the interface, contributing to an enhanced bonding quality. Compression testing further revealed a high-quality bonding of TA2/Q235 cladded pipes. Nano-indentation measurements showed enhanced hardness values in both Q235 and TA2 regions compared with the base materials, which substantiates the effectiveness of the optimised welding parameters.
