I have a problem with my reseach, i want to know the influence of
those flux ability to change the properties of weld metal. Know i was
found an advantage that flux TiO2 can increase the mechanical
properties of weld metal. from the AWS Standard they say that E6013
will have 430-460 MPa of minimum strength, but i had 508 MPa with
E6013 by adding flux TiO2 in electrode face.
My analysis now just from the mechanical test, i was find an acicular
ferrite structure in this research. But i don't know how the
accicular ferrite function for the mechanical properties of weld metal
and the theory of the influence of flux TiO2, MnO and Al2O3
accurately.
I need yours help for all members that want to partcipate.
thanks so much...
note : this research done in Mechanical Engineering Departmet,
University of Andalas, West Sumatra, Indonesia.
