GATE MT 2021 Q40. A continuous fillet weld is made using a 3000 W welding machine. At a travel speed of 6 mm s-1, the cross-sectional area (in mm2) of the weld is: (round off to nearest integer). Given: The unit energy required to melt the metal is 6 J mm-3.Heat transfer factor = 0.6 Melting factor = 0.5

Answer: 25 mm^2 Note:- 1-Heat transfer factor is the ratio of the actual heat received at the work surface divided by the total heat generated by the source. 2- Melting factor is the ratio of heat used for melting divided by the heat received at the work surface. SOLUTION:-
