The term temperature refers to the degree or level of energy in a material and can be measured in degrees with a thermometer. The term heat refers to the quantity of energy in a material and cannot be easily measured. The quantity of heat in a material can be determined by knowing both the temperature and mass (weight) of an object. Likewise, the temperature of an arc from a small diameter electrode is the same as the arc from a large diameter electrode, but the larger arc has more heat. What is the typical temperature of an arc? The temperature … Continue reading How welding Arc heat, Temperature be produced?
