TIG welding of thin plates will give steeper thermal gradients than submerged arc welding of thick plates, the latter process will have the higher heat input.

TIG welding of thin plates will give steeper thermal gradients than submerged arc welding of thick plates, the latter process will have the higher heat input. Correct Answer True

The above mentioned statement is true. Here the base metal is an efficient heat sink and the temperature noticed directly underneath the arc is so high, hence as a consequence the degree of super cooling turns be so low.

To effect a bond between two metal plates, 2.5 cm and 15 cm thick, heat is uniformly applied through the thinner plate by a radiant heat source. The bonding must be held at 320 K for a short time. When the heat source is adjusted to have a steady value of 43.5 k W/m2, a thermocouple installed on the side of the thinner plate next to source indicates a temperature of 345 K. Calculate the temperature gradient for heat conduction through thinner plate. In the diagram, the upper plate is 2.5 cm thick while the lower is 15 cm thick.
