Welding of dissimilar materials (2)
The position of the material in the Schaeffler diagram is determined from its
chromium and nickel equivalents, and a straight line is then drawn between the points.
Similarly, the position of the proposed filler material is plotted. When welding symmet-
rical joints, it can be assumed that the joint surfaces of the base material will be more or
less equally melted. A straight line can therefore be drawn between the position of the
filler material and the centre of the line between the base materials. In general, about
40 % of the filler material will be 'diluted' by the molten base material, with the result
that the structure of the weld metal will be as indicated by a point about 20-40 % of the
way along the line from the position of the filler material. If this structure is suitable,
then the proposed filler material can be used. If it is not suitable, repeat the above
procedure for a filler having a different composition.
