Proceedings <strong>of</strong> the National Conference on<br />

Trends and Advances in Mechanical Engineering,<br />

3. Confirmation test results:<br />

As a result five samples have been welded at the optimum condition as above with<br />

HARDNESS are 176,178; 166, 174; 187, 182; <strong>19</strong>4, <strong>19</strong>0 and 177, 179. The samples have been<br />

evaluated following the same criteria used for the original experiments. The average <strong>of</strong> the<br />

Control Factor Names Optimum Level Optimum Value<br />

Electrode Diameter A1 2.4 mm<br />

Wire Diameter B3 2.9 mm<br />

Welding Current C3 130 Amp<br />

Argon Flow D3 9 L/min<br />

sample has been found to be 180.3 V.H.N. which is within the confidence interval. The<br />

increase in hardness has been found to be 36.4 %<br />
