It also means we can grind the electrode tip to a sharp, conical point to concentrate the arc, and it won't deteriorate quickly. This can be made by first grinding to a thin taper, and then grinding a 0.10 0.30 flat land on the end of the tungsten, which will prevent ball formation. The thickness of the rod determines the amount of filler metal deposited after you dab it in the weld pool, but it also determines the amount of energy needed to melt that rod diameter. The first two welding rod numbers stand for the tensile strength of the filler material. AC TIG is generally used to weld aluminum and magnesium materials. How to Calculate the Diameter of Welding Electrode Needed This is the question often asked by customers facing new tasks. These diameters are inch measurements but we will show the metric conversion as well. Access SmartBlog Category. Tungsten of different lengths used in TIG welding refers to tungsten of different diameters. Yolo manufactures and sell a wide range of pregroundtungsten tips for tig welding.

Ceriated tungsten electrodes contain about two percent cerium oxide (CeO2), referred to as ceria. Maintenance of the protective gas must be strictly observed not only during welding but also when the arc is disconnected until the end of the electrode cooled. Lift Arc. Smaller diameter electrodes will start the arc more readily at very low amperage settings. Here are the most common diameters used in TIG welding. The grinding should be done straight and not at 90 degrees. The inert gas, normally argon or helium provides a shield around the electrode, allowing it to maintain a very high temperature arc without burning up. If you have questions about choosing the right tungsten electrode for your next weld job, dont hesitate to, , no one does it better than SPARC. 3 types of TIG.
