How to Cut Welding Tungsten
To cut welding tungsten, you will need a few essential tools: a tungsten grinder, cutting pliers, and a vise.
Start by securing the tungsten rod in the vise, making sure it is held tightly.
Then, use the cutting pliers to score the tungsten rod where you want to make the cut.
Apply steady pressure and make a clean cut through the scored line.
Finally, use the tungsten grinder to smooth out any rough edges.
Cutting welding tungsten requires precision and proper tools to ensure a clean and accurate cut.

Did You Know?
1. Did you know that cutting welding tungsten can be done using a simple hacksaw? This method is often used when there is no access to power tools or if the tungsten piece is too small for conventional cutting methods.
2. Tungsten has the highest melting point of any element, reaching a whopping 3,422 degrees Celsius (6,192 degrees Fahrenheit)! This property makes it an ideal choice for welding applications as it can withstand extremely high temperatures without losing its structural integrity.
3. During World War II, tungsten was considered a strategic material and was heavily relied upon for the production of weapons and ammunition. In fact, countries such as the United States included tungsten in their list of critical materials, ensuring its availability for military purposes.
4. The name “tungsten” derives from the Swedish words “tung sten,” which mean “heavy stone.” This is fitting since tungsten has an exceptionally high density, almost twice that of lead.
5. Tungsten is an essential component in the manufacture of incandescent light bulbs. The filament in these bulbs is made from tungsten due to its high melting point, allowing it to emit a bright and consistent light when heated.
Introduction To Cutting Welding Tungsten
Welding tungsten is a crucial material used in the welding industry due to its exceptional durability and high melting point. It is commonly used as an electrode material for various welding applications. However, cutting tungsten to the desired length is often a necessary step before it can be effectively utilized. This article focuses on providing insights and guidance for safely and efficiently cutting welding tungsten.
Buying Welding Tungsten: Local Welding Supply Store (LWS)
When purchasing welding tungsten, a convenient option is to visit a local welding supply store (LWS). These stores provide a variety of welding materials and equipment, including welding tungsten. It is important to exercise caution when opting for the cheaper welding tungsten available at these stores.
Experiences With Bad Batches Of Welding Tungsten
In my personal experience, I have encountered a few cases of bad batches when purchasing welding tungsten from local welding supply stores. These instances include containers that split randomly, leading to potential contamination and wastage of tungsten. Such occurrences can be frustrating and highlight the importance of scrutinizing the quality of the product before making a purchase.
Issues With Tungsten OD And Collet Tightness
Another issue I have come across regarding welding tungsten is its odd outer diameter (OD) under 1/8. This thinner diameter can pose challenges in terms of keeping the tungsten tight in the collet, leading to instability during welding. It is crucial to ensure a secure grip on the tungsten to achieve precise and quality welds.
Comparison Of Name Brand Welding Tungsten
To address the potential drawbacks associated with cheaper welding tungsten options, some welding professionals opt for name brand products. However, in my own experience, I have not noticed a significant difference in performance or quality between various name brands. While individual preferences may vary, it is worth considering if the higher cost truly justifies the perceived benefits.
Conclusion: No Significant Difference In Brand Preference
Cutting welding tungsten is a crucial step in the welding process that requires careful consideration when purchasing this material. While local welding supply stores offer convenience and potential cost savings, it is essential to inspect the product for signs of poor quality. Moreover, the odd OD of some welding tungsten may pose challenges with collet tightness, emphasizing the need for a secure grip to ensure optimal welding performance. When comparing name brand options, it may be found that there is no significant difference in preference, and the decision ultimately depends on individual preferences and budget constraints. By following these guidelines, you will be well-equipped to safely and efficiently cut welding tungsten, ensuring high-quality welds in your projects.
Frequently Asked Questions
What do you use to cut tungsten?
When it comes to cutting tungsten, using a diamond saw blade would be an effective choice. The hardness of tungsten necessitates a cutting tool that can handle its durability, and a diamond saw blade is capable of precisely slicing through this challenging material with ease. Another option might be using a plasma cutter, which generates a high-temperature plasma arc to swiftly and accurately cut through tungsten. Both methods offer efficient ways to cut tungsten, providing smooth and clean results.
How do you cut tungsten bars?
To cut tungsten bars effectively, there are several methods that can be employed. One approach is using an abrasion wheel grinding technique, which grinds down the tungsten carbide rods to the desired size. Another method involves machining by super hard materials, where a tool made of exceptionally hard materials is used to cut through the tungsten bars. Alternatively, electrolytic machining (ECM) can be utilized, where an electric current is passed through an electrolyte solution to dissolve the tungsten and achieve the desired shape. Additionally, electric discharge machining (EDM) can be employed, which involves using electrical discharges to erode the tungsten bars and cut through them effectively.
How do you shape the end of a tungsten electrode?
In order to shape the end of a tungsten electrode, the recommended approach involves a two-step process. First, carefully grind the tungsten to achieve a taper, as mentioned earlier. Once the taper is achieved, it is essential to then grind approximately 0.2-0.5 mm of the tip to create a flat end. The purpose of this flat end is to prevent the transfer of tungsten through the arc and the formation of a ball end. By following these steps, the tungsten electrode can be properly shaped, ensuring optimal performance and preventing any unwanted issues during use.
What is the easiest way to cut tungsten?
When it comes to cutting tungsten, the most effective method involves utilizing a diamond cutting wheel. This is crucial due to tungsten’s exceptional hardness, which requires a tool equally as resilient to achieve consistent and clean cuts. The diamond cutting wheel ensures precision and durability during the cutting process, enabling the successful manipulation of this tough material.
