2. How does the percentage of lanthanum in the tungsten electrode affect its performance?

3. What are the common uses of lanthanated tungsten electrodes in welding?

## Answer:

1. When choosing lanthanated tungsten for a specific application, several factors should be considered. These include the type of material being welded, the welding current, the welding method (AC or DC), and the welding position. It is crucial to match the electrode diameter and type to the welding parameters to ensure optimal performance.

.

2. The percentage of lanthanum in the tungsten electrode is a critical factor that affects its performance. Lanthanum helps improve the stability of the arc, reduce the tendency for the tungsten to contaminate the weld, and enhance the electrode's longevity. The higher the percentage of lanthanum in the electrode, the greater these benefits will be. It is essential to select the appropriate lanthanum content based on the specific welding requirements.

3. Lanthanated tungsten electrodes are commonly used in a variety of welding applications. They are particularly well-suited for AC welding of aluminum alloys due to their ability to maintain a stable arc and resist tungsten contamination. Lanthanated tungsten electrodes can also be used for DC welding of carbon and stainless steels, nickel alloys, and titanium. Their versatility, durability, and ease of use make them a popular choice among welders for a wide range of applications.
