Thermal Efficiency and Heat Input in Welding:
Thermal Efficiency:
The thermal efficiency of a process is a measure of how effectively it converts input energy into useful output energy. In the case of welding, thermal efficiency refers to the ratio of the heat input to the heat output. It is given by the formula:
Thermal Efficiency = (Heat Output / Heat Input) * 100
Net Heat Input:
The net heat input in welding refers to the amount of heat energy transferred to the workpiece per unit length of the weld. It is typically measured in kJ/cm.
Calculating Net Heat Input:
To calculate the net heat input, we need to know the thermal efficiency and the heat output. Since the thermal efficiency is given as 65%, we can use this information to determine the net heat input.
Formula:
Thermal Efficiency = (Heat Output / Heat Input) * 100
Rearranging the formula, we get:
Heat Output = (Thermal Efficiency / 100) * Heat Input
Substituting Values:
Since the thermal efficiency is given as 65%, we can substitute this value into the formula:
Heat Output = (65 / 100) * Heat Input
Range of Heat Input:
To find the range of the net heat input, we need to consider the possible values for the heat input. Since the correct answer is between 23 and 24 kJ/cm, we can assume that the heat input falls within this range.
Calculating Heat Output:
Using the range of heat input, we can calculate the corresponding heat output:
Heat Output = (65 / 100) * Heat Input
For Heat Input = 23 kJ/cm:
Heat Output = (65 / 100) * 23 = 14.95 kJ/cm
For Heat Input = 24 kJ/cm:
Heat Output = (65 / 100) * 24 = 15.6 kJ/cm
Conclusion:
Based on the calculations, the net heat input per unit length of weld is between 14.95 and 15.6 kJ/cm. Therefore, the correct answer is between 23 and 24 kJ/cm.
