Abstract
through super-hard wear-resistant surface electrode surfacing D707 in Low-carbon steel. We have analysis the effect of welding process parameters and post-weld heat treatment process on low carbon steel surface hardness of cladding layer. The experimental results show that: after quenching hardness value no significant change; But after annealing the hardness value decreased and after annealing the crystal grain of the underlying tissues uniformization become tiny. micro-hardness testing is carried out in the weld cross-section, we have find out that from the base metal to the cladding layer the surface hardness values is getting higher and higher, while the indentation is getting smaller and smaller. Because hardness is a measure of wear resistance materials, thus it can indirectly show that when low-carbon steel surface electrode in the super-hard wear-resistant surfacing welding layer, it can improve the surface hardness of low carbon steel and improve wear resistance of low carbon steel surface.
