strength and toughness of welds. Figures 3, 4 and 5
show how heat input and interpass temperatures affect
0.2%-proof strength, tensile strength and notch
toughness of MG-60 all-deposited metals. In these
figures, it is obvious that the higher the heat input and
interpass temperature, the lower the strength and
toughness of the welds. These test results suggest that
the heat input and interpass temperature should be
controlled up to 30kJ/cm and 250°C respectively in the
use of MG-60 in order to maintain sufficient strength
and toughness.

The Use of Proper Currents and Voltage Provides a Stable, Gentle Arc with Low Spatter MG-60 offers a stable, gentle arc with low spatter of fine particles when compared with conventional solid wires when proper currents and arc voltage are used. As shown in Fig. 6, the use of MG-60 can decrease the amount of spatter by approximately 15% when compared with a conventional wire.
