FAQs

What are tungsten electrodes used for?

Tungsten electrodes are a vital consumable used in Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW). They create the concentrated arc that melts the base metal to form a strong weld. The specific type of tungsten chosen impacts factors like arc stability, current capacity, and the type of metal being welded.

What are the different types of tungsten electrodes?

There are several main types of tungsten electrodes, each with its strengths and ideal applications:

• Pure Tungsten (Green): Best for AC welding aluminium and magnesium due to its low work function and ability to handle high temperatures.
• Cerium Oxide (Ceria) Tungsten (Grey/Orange): Known for its stability and ease of starting the arc, particularly at lower amperages on DC welding of thin materials.
• Lanthanum Oxide (Lanthanated) Tungsten (Black/Gold/Blue): Offers a good balance between ceria and thoriated tungsten, providing good arc stability for AC/DC welding on various materials like carbon steel, stainless steel, and nickel alloys. (Note: While previously common, thoriated tungsten is less favoured due to radioactivity concerns.)
• Zirconiated Tungsten (White/Brown): Primarily used in AC welding for its ability to withstand contamination and provide a stable arc.

How do I choose the right tungsten electrode?

The ideal tungsten electrode depends on several factors:

• Current type (AC or DC): Some electrodes are designed specifically for AC or DC current.
• Metal being welded: Different metals require electrodes with specific properties for optimal weld quality.
• Base metal thickness: Electrode selection may vary depending on whether you’re welding thin or thick materials.
• Amperage: The electrode diameter should be appropriate for the amperage you’ll be using.

What are the benefits of using high-quality tungsten electrodes?

High-quality tungsten electrodes offer several advantages:

• Superior arc starts: Easier ignition for a smooth and efficient welding process.
• Reduced tungsten spitting: Minimises contamination of the weld pool for cleaner welds.
• Improved arc stability: Ensures a consistent and focused arc for better weld control
• Extended electrode life: Lasts longer, reducing replacement frequency.

How do I care for tungsten electrodes?

• Sharpen properly: Use a dedicated tungsten grinder to create a clean, sharp tip for optimal arc performance.
• Avoid contamination: Keep the electrode clean and free of oil, grease, or other contaminants.
• Store properly: Store electrodes in a dry, protected environment to prevent damage.

By understanding these key points, you can select the right tungsten electrode for your TIG welding projects and achieve optimal results.
