TIG Fill Wire 5kg: Technical Properties & Specifications

Understanding the chemical metallurgy and structural physics that drive flawless, zero-defect TIG (GTAW) welding operations.

Optimal Wire Chemistry & Deoxidization

TIG welding (Gas Tungsten Arc Welding) requires an extremely clean weld pool. When working with carbon steels (like ASTM A36) or low alloy steels, residual mill scale and surface rust can trigger pocket porosity. Our ER70S-6 TIG Solid Wire features enhanced levels of silicon (Si: 0.80% - 1.15%) and manganese (Mn: 1.40% - 1.85%). These elements act as powerful deoxidizers, combining with oxygen and impurities to form slag that floats to the surface, leaving behind a clean, porosity-free joint.

For stainless steel projects, we supply ER308L and ER316L grades. By controlling carbon content under 0.03%, we prevent chromium carbide precipitation at grain boundaries. This is crucial for avoiding intergranular corrosion in chemical processing plants and high-temperature environments.

Why the 5kg Spool/Box Configuration Matters

While manual TIG welding often uses 1000mm straight rods, the 5kg spool format is increasingly preferred for modern mechanised and semi-automatic GTAW setups. It offers several benefits:

  • Continuous Wire Feed: Ideal for automatic orbital TIG machines, allowing long run times without interrupting the gas shield.
  • Precision Layer-Winding: Every spool is precision-wound to prevent tangles and micro-slips during wire feed, ensuring a stable arc length.
  • Optimal Protection: Compact packaging makes it easy to store in clean dry lockers, minimizing moisture absorption.
AWS Classification C (%) Mn (%) Si (%) P & S (%) Typical Yield Strength Elongation (%)
ER70S-6 0.06 - 0.15 1.40 - 1.85 0.80 - 1.15 ≤ 0.025 ≥ 420 MPa ≥ 22%
ER308L ≤ 0.03 1.00 - 2.50 0.30 - 0.65 ≤ 0.030 ≥ 350 MPa ≥ 35%
ER316L ≤ 0.03 1.00 - 2.50 0.30 - 0.65 ≤ 0.030 ≥ 370 MPa ≥ 30%

China Factory 4.0: Supply Chain Resilience & Manufacturing Excellence

Inside Wulian Yuxin's advanced workshop where precision engineering meets high-volume output capability.

With an annual capacity of 3,000 tons, our facility relies on advanced automated production to ensure consistent quality. Every wire drawer and spooling line is monitored for tolerances that are 30% stricter than standard industry requirements. We control the process from raw wire drawing to final copper coating and layer winding.

This vertical integration ensures our clients benefit from stable pricing and guaranteed delivery schedules, even during global supply chain volatility. Our facility features advanced inline detection equipment that checks for copper coating consistency and diameter uniformity, preventing issues like micro-arcing and liner wear during use.

To reduce carbon footprint and meet European ESG import demands, Wulian Yuxin is introducing eco-friendly paper packaging and recycled plastic spools. Our 15,000-square-meter facility operates with low-waste processes, ensuring compliance with strict environmental regulations.

Frequently Asked Questions

Common questions from procurement directors and engineering managers regarding our TIG welding wires and services.

Q1: What is the main difference between ER70S-6 and other carbon steel wire grades?
ER70S-6 contains higher levels of Manganese and Silicon deoxidizers. This makes it more forgiving when welding over mill scale, minor rust, or surface contaminants compared to grades like ER70S-3, helping to prevent porosity.
Q2: How does Wulian Yuxin ensure uniform copper coating on the wires?
We use an inline chemical electroplating process during drawing. This control ensures consistent electrical conductivity, stable arc performance, and reduced tip wear, while helping to prevent rust during storage.
Q3: What certifications accompany your shipments?
Our products meet ISO9001 and CE requirements. We provide chemical analysis, mechanical property test reports, and mill test certificates (MTC) to meet regulatory requirements.
Q4: What packaging options are available for the 5kg wire configuration?
The 5kg wire is precision wound on standard-dimension spools, sealed in vapor-barrier bags, and packed in reinforced cardboard boxes. We can also provide custom brand packaging for OEM orders.
Q5: Do you support custom chemical composition requirements?
Yes, for qualified order volumes, our metallurgy team can adjust element levels within the AWS range to match specific design requirements, such as controlling silicon levels for particular slag behaviors.
