TIG Welding Services at Greno Industries

TIG welding—also known as Gas Tungsten Arc Welding (GTAW)—is one of the most precise and controlled welding processes available today. At Greno Industries, TIG welding plays a critical role in producing high‑integrity components for demanding applications in power generation, defense, heavy equipment, and industrial machinery.

While MIG welding supports high‑volume fabrication, TIG welding is the method of choice when accuracy, cleanliness, and metallurgical quality are paramount. Among its advantages, TIG welding is widely recognized for producing exceptionally clean, high‑quality welds on metals such as stainless steel, aluminum, and exotic alloys, making it essential for industries where weld integrity cannot be compromised.

What Makes TIG Welding Unique?

TIG welding uses a non‑consumable tungsten electrode to generate an arc while shielding gas—typically pure argon—protects the weld pool from contamination. Filler metal is added manually, giving the welder full control over heat input and bead formation. This level of precision is why TIG welding is often described as the “gold standard” for high‑accuracy fabrication.

Unlike MIG welding, which uses a continuously fed wire electrode, TIG welding separates heat generation from filler addition. This allows for:

• Exceptional weld appearance

• Minimal spatter

• Superior control over penetration

• Reduced distortion

• High‑quality welds on thin or heat‑sensitive materials

Ultimately, TIG welding is ideal for applications requiring flawless welds, tight tolerances, and metallurgical stability.

TIG Welding at Greno Industries

Greno Industries integrates TIG welding into our broader machining and fabrication workflow, ensuring that welded components meet the same high standards as our CNC‑machined parts. TIG welding is especially valuable for:

• Stainless steel components

• Thin‑wall tubing

• Precision assemblies

• High‑temperature alloys

• Critical turbine and power‑generation parts

Because TIG welding requires a high degree of operator skill, Greno’s welders are trained to maintain consistent torch angle, travel speed, and heat input—factors that directly influence weld quality and structural performance.

Applications Across High‑Demand Industries

TIG welding supports many of the same markets served by Greno’s machining operations, including:

Power Generation

In the power generation industry, turbine components, housings, and high‑temperature alloys often require TIG welding due to its ability to maintain metallurgical integrity under extreme conditions.

Defense and Military

Precision welds are essential for components exposed to vibration, shock, and thermal cycling. TIG welding provides the reliability required for mission‑critical hardware in defense and military applications.

Heavy Equipment

Hydraulic components, brackets, and structural parts benefit from TIG’s clean, strong welds—especially when working with stainless steel or alloy steels.

Industrial Machinery

TIG welding supports custom assemblies, repairs, and prototype development where accuracy and repeatability matter in industrial manufacturing.

Quality Control and Welding Precision

Greno’s TIG welding operations follow industry‑recognized best practices, including:

• Proper tungsten selection (material and diameter) based on the metal being welded

• Shielding gas purity and flow control to prevent porosity

• Heat‑input management to avoid warping or metallurgical degradation

• Surface preparation to ensure clean, contaminant‑free joints

• Process monitoring to maintain consistency across production runs

TIG welding’s sensitivity to parameters makes process control essential. Each adjustment—current, gas flow, electrode type—directly affects weld quality, making TIG a process that rewards precision and expertise.

Why TIG Welding Matters at Greno

TIG welding enhances Greno’s ability to deliver complete, ready‑to‑install components. By combining machining, fabrication, and welding under one roof, Greno reduces lead times, improves quality control, and ensures that every welded assembly meets the performance requirements of high‑demand industries.

TIG Welding FAQs

What is TIG welding used for at Greno Industries?

TIG welding is used for precision‑critical components, thin‑wall materials, stainless steel, and high‑temperature alloys. It supports turbine parts, defense components, and custom industrial assemblies.

What materials can be TIG welded?

TIG welding works on stainless steel, carbon steel, aluminum, titanium, Inconel, magnesium, and other exotic alloys. Its versatility makes it ideal for high‑performance applications.

How does TIG welding differ from MIG welding?

TIG welding uses a tungsten electrode and manually added filler rod, offering greater control and cleaner welds. MIG welding uses a continuously fed wire and is faster for high‑volume production.

Why choose TIG welding for precision components?

TIG welding provides unmatched heat control, minimal spatter, and excellent weld appearance—making it ideal for tight‑tolerance parts and heat‑sensitive materials.

Is TIG welding suitable for repairs?

Yes. TIG welding is often used for repairing thin materials, stainless steel, and high‑value components where precision and metallurgical quality are essential.

Does Greno offer both prototype and production TIG welding?

Absolutely. Greno supports one‑off prototypes, short‑run fabrication, and full‑scale production TIG welding with consistent quality across all parts.
