Here is the English translation of the detailed explanation about TIG welding applications.
TIG welding, known for its high precision and superior weld quality, is considered a premium welding process. It uses a non-consumable tungsten electrode and an inert shielding gas (such as argon).
Stainless Steel Piping and Fittings: Ideal for pipelines transporting food, pharmaceuticals, and chemicals because it produces perfectly clean, pore-free welds resistant to corrosion.
Fabrication of Stainless Steel (SS) Tanks: Used for constructing storage tanks for raw materials, process vessels, and reactors that require a perfectly smooth and hygienic internal surface.
Welding Sensitive Engine and Airframe Components: Welding titanium alloys, stainless steels, and specific aluminum alloys used in high-temperature and high-pressure environments.
Fabrication of Hydraulic and Fuel Systems: Joining pipes and fittings with very high precision and reliability.
Root Pass for Pressure Pipes: Used for the first weld layer (root pass) in critical piping to achieve high quality and complete penetration.
Welding Nickel and Inconel Alloys: These high-temperature alloys are often welded using TIG.
Repair of High-Value Components.
Fabrication of Stainless Steel and Titanium Exhaust Systems: Especially in racing and luxury vehicles.
Fabricating Chassis for Specialty Cars and Carbon/Aluminum Bicycles.
Repair of Aluminum Engine and Cylinder Head Components.
Welding Aluminum Hulls for Boats and Ships: Aluminum is widely used in shipbuilding due to its resistance to saltwater corrosion, and TIG is the best method for high-quality welds.
Repair of Stainless Steel Marine Structures.
Creating Metal Sculptures: Allows artists to work with great precision on various metals.
Fabrication of Stainless Steel Railings, Benches, and Decorative Elements: To create beautiful, uniform weld seams (which often require polishing).
Fabrication of Modern and Designer Furniture.
Welding Copper and Copper Alloys: For manufacturing heat exchangers, coils, and radiators.
Repair of Plastic Molds and Die-Casting Molds.
Welding Magnesium and Other Special Metals.
Highest Weld Quality: Produces very clean welds with excellent penetration and minimal defects (such as cracks and porosity).
Superior Control: The welder can independently control the heat input and the amount of filler metal.
Ability to Weld a Wide Range of Metals: Includes stainless steel, aluminum, copper, magnesium, titanium, nickel, and even reactive metals like titanium.
Slag-Free Welds: No slag is produced, so the final weld is very clean and requires no cleanup.
Welding in All Positions: Enables welding in difficult positions.
Focused and Narrow Arc: Ideal for welding edges and very narrow joints.
Low Speed: Significantly slower than methods like MIG/MAG.
High Skill and Experience Required: Demands a highly skilled and experienced welder.
Sensitivity to Contamination: The base metal surface and filler rod must be perfectly clean and free of oil, paint, and oxide (especially for aluminum and titanium).
High Cost of Equipment and Gas.
TIG welding is a process for "first-class" and sensitive applications. It is used where quality, precision, cleanliness, and reliability take precedence over speed and cost. This process is the king of welding non-ferrous metals like aluminum and titanium, and is also the premier choice for stainless steel in hygienic and critical industries.
