Heat distribution in spot welding
Besides the resistance at the interface, there are six other resistance through which the same welding current is passed. They are:
Therefore, some amount of heat is generated in these regions also (equal to I2 x R x t).The effective heat that is utilised is that due to the resistance at the metal - metal interface only, the others being losses.Among the above six resistance, R2 and R5 are high compared to the other four. These two can be minimised by properly choosing the electrode pressure and cleaning the surface well.
Explain the Laws of Thermodynamics Usually thermodynamics contains four laws; a. Zeroth law: this law deals with thermal equilibrium and establishes an idea of temperature.
For Elevated Temperatures, Other Materials High temperature creep is a significant phenomenon to be guarded in various machines like gas turbines, missiles, reentry vehicles a
