Explanation
- Constants:
INITIAL_TEMPERATURE
: The initial temperature before welding starts.WELDING_TEMPERATURE
: The temperature reached during the welding process.COOLING_RATE
: The rate at which the temperature decreases per second after welding stops.WELDING_DURATION
: The duration of the welding process.TIME_STEP
: The time increment for each step of the simulation.
- simulateWelding Function:
- Simulates the welding process, including both heating and cooling phases.
- Heating Phase: The temperature is set to
WELDING_TEMPERATURE
for the duration of welding. - Cooling Phase: After welding stops, the temperature decreases at a rate defined by
COOLING_RATE
until it returns to theINITIAL_TEMPERATURE
.
- Main Function:
- Calls
simulateWelding
to get a list of temperatures over time. - Outputs the time and corresponding temperature values, showing the temperature changes during and after the welding process.
- Calls
Usage
- Initial Temperature: Set to 20°C, representing the starting temperature before welding.
- Welding Temperature: Set to 1500°C, simulating the high temperature during the welding process.
- Cooling Rate: Affects how quickly the temperature decreases after welding stops.
- Welding Duration: The period during which welding occurs before cooling begins.
