The weld metal of carbon ferritic the hardness values observed.

Figure 12 demonstrates the microstructure of the root pass of the joint welded with several passes.A significant
amount of ferrite with an aligned second phase(FS(A))and grain-shaped ferrite(PF(G))may be observed along with
some acicular ferrite(AF).In this qualitative analysis,no presence of martensite(M)or aggregate of ferrite-carbide
was verified.The microstructure obtained is typical of the weld metal of low carbon ferritic the hardness values observed.
