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?
The voltage and arc length are closely related. The shorter the arc, the lower the arc voltage and the lower the temperature produced, an as the arc lengthens, the resistance increases, thus causing a rise in the arc voltage and temperature. Most shielded metal arc welding electrodes have chemicals added to their coverings to stabilize the arc. These arc stabilizers form conductive ions that make the arc more stable and reduce the arc resistance. This makes it easier to hold an arc. By lowering the resistance, the arc stabilizers also lower the arc temperature. Other chemicals within the gaseous cloud … Continue reading Welding Voltage & Arc Length Relationship
