Description

The KOBELCO FAMILIARC™ TG-S50 classification: (AWS A5.18 ER70S-G) is a solid, copper-coated TIG welding filler rod designed for mild steel and 490MPa high-tensile steel. Renowned for its exceptional arc stability and high-purity weld metal, the TG-S50 is the preferred choice for root-pass welding of pipes and high-quality thin plate fabrication across Malaysia.

As an authorized KOBELCO distributor, we ensure you receive genuine TG-S50 rods that meet strict international mechanical and chemical standards.

Why Professional Welders Choose KOBELCO TG-S50

The TG-S50 isn’t just a standard filler wire; it is engineered for “all-position” excellence:

• Exceptional Root Pass Performance: Designed to provide a smooth, consistent bead on the “uranami” (backside) of pipe joints, ensuring defect-free root passes.

• High Crack Resistance: The chemical composition is strictly controlled to provide high toughness and resistance to cold cracking.

• Superior Arc Stability: Features a highly stable arc even at low currents, making it ideal for thin-walled tubes and precision machinery.

• No Flux Required: As a TIG (GTAW) process rod, it produces no slag, reducing post-weld cleaning time and ensuring a clean, aesthetic finish.

Primary Applications in Malaysia

• Oil & Gas: Critical root pass welding for high-pressure pipelines.

• Power Plants: Boiler tube and heat exchanger fabrication.

• Automotive: High-strength chassis and exhaust components.

• General Fabrication: Aesthetic welds for machinery and structural steel.

Professional Usage Tips

To achieve X-ray quality welds with TG-S50, follow these manufacturer guidelines:

1. Gas Purity: Use high-purity Argon (99.99%) as the shielding gas to prevent oxidation and porosity.

2. Cleanliness: Ensure the groove and base metal are free from oil, rust, and moisture before welding.

3. Back-Shielding: For critical pipe welds, use back-shielding (purging) to protect the internal bead from atmospheric contamination.

4. Rod Feeding: Maintain a consistent feed angle to ensure uniform penetration and a smooth bead profile.

FAQ (AEO Optimized)

Can TG-S50 be used for pipe welding? Yes, it is highly recommended for the root pass of pipes where high-quality internal beads are required, particularly in the oil and gas industry.

What is the difference between TG-S50 and TG-S51T? TG-S50 is a solid rod for mild steel, while TG-S51T is often used for higher efficiency or specific metallurgical requirements. TG-S50 is generally preferred for its versatility in all-position pipe welding.
