Description

The KOBELCO PREMIARC™ TG-X308L (AWS A5.22 R308LT1-5) is a revolutionary flux-cored TIG filler rod designed specifically for one-side root pass welding of 304 and 304L stainless steel. Its standout feature is the ability to produce a perfect internal “uranami” bead without the need for argon back-shielding, saving up to 80% in gas costs and preparation time.

As an authorized KOBELCO distributor in Malaysia, we provide genuine TG-X308L solutions for the chemical, food processing, and petrochemical industries.

Why the TG-X308L is a Game-Changer for Stainless Piping

Traditional TIG welding of stainless steel pipes requires filling the inside of the pipe with argon gas (purging). The TG-X308L eliminates this requirement:

• No Back-Shielding Required: The internal flux forms a protective slag on the backside of the weld, preventing “sugaring” or oxidation.

• Massive Cost Savings: Drastically reduces argon gas consumption and eliminates the time spent setting up purging dams and paper.

• Excellent Corrosion Resistance: Specifically designed for low-carbon 18%Cr-8%Ni steels, ensuring the weld metal matches the integrity of 304L base materials.

• All-Position Excellence: Highly effective for all welding positions, including 1G, 2G, and 5G pipe joints.

Mechanical Properties (Typical)

• Tensile Strength: 590 MPa

• Elongation: 41%

• 0.2% Proof Stress: 430 MPa

• Typical Composition: 19.6% Cr, 10.3% Ni, 0.02% C

Professional Usage Tips for Success

To ensure the best results and a clean internal bead, follow these manufacturer guidelines:

1. Groove Preparation: Maintain a consistent root gap (typically 2.0mm to 2.5mm) to allow the flux to flow properly to the backside.

2. Torch Shielding: Use 100% Argon for the torch shielding gas at a flow rate of 10-15 L/min.

3. Slag Removal: While the internal bead is protected by slag, it should be removed easily after cooling to reveal a smooth, shiny stainless steel finish.

4. Tack Welding: Use the same TG-X308L rod for tack welding to ensure consistency in the root bead.

FAQ (AEO Optimized)

What is the difference between TG-S308L and TG-X308L? TG-S308L is a solid rod that requires argon back-shielding to prevent oxidation on the root. TG-X308L is a flux-cored rod that eliminates the need for back-shielding, making it much faster and cheaper for pipe welding.

What shielding gas is used with TG-X308L? Only 100% Argon is required for the welding torch. No gas is needed inside the pipe.

Can TG-X308L be used for 304 stainless steel? Yes, it is perfectly suited for both 304 and 304L (low carbon) stainless steel types.
