Tungsten inclusion is a welding defect found in gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding. This welding process uses a non-consumable tungsten electrode to generate an arc—and a tungsten inclusion occurs when some of the material from this electrode is deposited into the molten…
Tungsten has been an important part of the welding industry with a specialized welding process named after it–TIG or Tungsten Inert Gas Welding. Since the 1940s, tungsten electrodes have proven to be a reliable component for welding a wide variety of metals including–aluminum, carbon steel, titanium, and many more. Tungsten…
Welding technology investments only become successful when manufacturers take the small details into account. These details can include weld parameters such as feed rate amperage, oscillation, and the material used during the process. Electrode selection, likewise, represents a relatively low-cost detail; however, an improperly selected electrode can result in thousands…
Tungsten electrodes are preferred in welding because they create excellent fusion in arc welding processes such as GTAW (Gas Tungsten Arc Welding) or PAW (Plasma Arc Welding). However, the same electrode can cause inclusions that present an issue during high-spec weld applications. To reduce the tungsten inclusion during GTAW, welders…
Tungsten is a robust metal with unique properties commonly used for the manufacturing of welding electrodes. It has the highest tensile strength of any metal and can retain it even at a high melting point of all at 3422° C (6192° F). This makes it an excellent choice for Gas…
Inconel® is a specialty metal that blends nickel and chromium together into an alloy that is extremely resistant to corrosion, even under extremes of heat and pressure that typically increase corrosion on metals like steel and stainless steel. Inconel is also far stronger than these more common metals, being able…
What is zirconiated tungsten used for? Zirconiated tungsten electrodes are generally used to weld metals whose surfaces have a higher melting point than the subsurface metals underneath. This type of tungsten is most widely used to weld aluminum using alternating current (AC). Zirconiated tungsten is also excellent at resisting contamination….
The properties of tungsten change when it is alloyed with thorium. For instance, a thoriated tungsten electrode has a greater current carrying capacity than pure tungsten. This allows it to carry more heat and reduces the potential for tungsten inclusions. It also makes a weld arc easier to start and…
Tungsten is an ultra-dense metal with unique properties that make it ideal for everything from high-strength machine tools to punching holes in armored vehicles. Its most salient property in the field of welding is its ability to endure very high heat without degradation of its tensile strength. This lets it…
Titanium has a curious nature. It is thought of as futuristic and expensive, and yet titanium is the ninth most abundant element in the Earth’s crust and the seventh most abundant metal. It’s so common, in fact, that titanium oxides are used in sunscreen and as pigment in white paint….
