TIG Welding: Refined Precision and Sustainable Results 

TIG welding, which stands for “Tungsten Inert Gas”, is an advanced method characterized by its concentrated arc and accuracy. This method involves the use of a stable electrode of tungsten or a tungsten alloy. A short circuit between the grounded workpiece and the positively charged electrode generates the heat. 

The unique aspect of TIG welding is that the electrode is not consumed during the process; only the base material and any additives melt. The electrode is continuously cooled, often with water, to maintain its temperature below the melting point, contributing to its longevity and cost-efficiency. To protect the weld joint, a shielding gas, usually pure Argon, is supplied. TIG welding can be performed with both direct and alternating current, and the heat is generated through short-circuiting between the grounded object and the workpiece.

We offer TIG welding procedures for a variety of materials, including Titanium from 1 mm to 80 mm thick, stainless steel 316L between 2-30 mm thick, C276 between 2-30 mm, CuNi 90/10 (Copper Nickel) between 2-10 mm, and 904L material between 2-20 mm. Additionally, we have procedures for Duplex materials between 2-7 mm, in accordance with standards such as EN15614-5 and ASME IX. With our expertise and modern equipment, we can deliver high-quality and precise welds for various industrial needs and projects.
