TIG or Tungsten Inert Gas welding is a highly demanding technique for diverse industries. These types of welding contain an essential component that refers to filler wires. A filler wire for TIG welding fills the gap between the welded metal pieces. The wire also strengthens the weld and lets you get a seamless finish. However, choosing the type of filler is essential to get the best results. Here, you will get a comprehensive guide on the right kind of wire and its applications.
Overview of TIG Filler Wire
A TIG filler wire is often available in metal-cored and solid forms. Solid wires consist of only one type of alloy material. In contrast, metal-core wires combine diverse metals, like aluminum alloy, stainless steel, and chromium-nickel to give the required weld strength.
Regardless of the type of TIG wire, you will get flux to promote sustainable arc stability during the welding process. Consider the specific application, type, and grade of material while choosing a filler wire type for the welding process. Simultaneously, you must check the joint fit-up configuration to achieve an optimum welding performance with fewer possible defects/problems during the weld operations.
Types of Filler Wires for TIG Welding
You will find various types of filler types of TIG welding wires from Castron Electrode, which include the following-
Aluminum Filler Wires
Aluminum filler wires work well for welding aluminum and its alloys. These wires provide seamless weld finishing. Accordingly, aluminum wires are perfect for the construction, automotive, and aerospace industries.
Copper Filler Wires
Copper filler wires weld copper and its alloys. They are in high demand in the electronic and electrical industries. The reason for this is that copper wires offer outstanding electrical conductivity to deliver the best results.
Mild Steel Filler Wires
Mild steel welding wire possesses a low percentage of carbon with a high iron percentage. Hence, one can consider it an ideal option to weld thin metallic sheets. Common applications of any mild steel TIG wire are general fabrication, construction, and automotive industry.
Stainless Steel Filler Wires
Filler wires made of stainless-steel work well to weld stainless steel only. These TIG wires possess nickel and chromium in a relatively high percentage. In this way, you will achieve the highest possible resistance to corrosion. Stainless steel-made wire is mainly used in the chemical, food processing, and pharmaceutical industries.
Nickel Filler Wires
Nickel filler wires are for petrochemical, chemical, and power generation industries. These wires may weld nickel and related alloys. Like stainless-steel wires, nickel wires even provide enough strength and corrosion resistance.
Conclusion
To conclude, selecting the appropriate type of filler wire is crucial to achieve success. Every filler wire comes with certain features and applications. Make sure you choose the right one to accomplish your job. Knowledge of different TIG welding/filler wires lets you make informed decisions.
