Hema Engineering Industries Metallurgy Engineer Interview Questions and Answers

Coil gape can be checked using a feeler gauge to measure the distance between the coils.

• Use a feeler gauge to measure the gap between the coils

• Ensure the coil is at room temperature before measuring

• Check for any irregularities or inconsistencies in the coil gape

Polymer percentage can be checked using techniques like thermogravimetric analysis, Fourier transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy.

• Use thermogravimetric analysis to measure the change in weight of a sample as it is heated, allowing for calculation of polymer percentage based on weight loss.

• Utilize Fourier transform infrared spectroscopy to analyze the chemical bonds present in a sa...read more

Core hardness can be checked using various methods such as Rockwell hardness test, Brinell hardness test, and Vickers hardness test.

• Use Rockwell hardness test for quick and easy measurement

• Use Brinell hardness test for larger core samples

• Use Vickers hardness test for small or thin core samples

• Ensure proper calibration of testing equipment

• Follow standard testing procedures for accurate results
