Do you know what type of alloy is known to have oxidation – and corrosion-resistant materials? Inconel, a brand name for specific nickel-chromium alloys, is well-suited for service in extreme environments subjected to pressure and heat.
It is often used by industries that use forged materials exposed to extreme heat because of this capability. However, did you know that it’s extremely hard to weld on its own?
Weld Inconel with TIG Welding
What is Titanium Inert Gas (TIG) Welding?
Titanium belongs in the family of reactive metals; meaning, it possesses a resilient affinity for oxygen. At room temperature, this metal reacts with oxygen to produce titanium dioxide. The passive and impenetrable coating combats further interaction from the surrounding particles. With titanium inert gas welding, manufacturers can secure the weld area from water vapor and oxygen.
How Does TIG Welding Enhance Inconel Welding?
As stated earlier, Inconel is generally complex to weld since the welds tend to crack because of too much heat and pressure. Nonetheless, certain types of Inconel are specially designed to be weldable.
In welding Inconel, industries must use an Inconel 625 filler metal. This is usually the most common weldable type of Inconel. According to metal experts, this type is useful in welding two pieces of Inconel together. Another good part of using Inconel 625 is that it can also be welded with other metals. For instance, most welding industries use stainless steel and Inconel to produce durable and heat-resistance metal.
For welding Inconel, you have to expect an ill-defined weld pool that may seem dirty and substandard for welders used to steel; however, this is normal. The important thing is that it welds a resilient and highly corrosion-resistant product.
