Industrial Grade TIG Welding Rods ER70S-2 – Buy Online at feelandeal.com

Achieve sound, porosity-free, and high-impact-resistant welds with premium ER70S-2 Mild Steel TIG Welding Filler Rods brought to you by feelandeal.com. Precision copper-coated for long shelf life and superior electrical conductivity, ER70S-2 is the premier choice for critical pipe welding, structural steel fabrication, and pressure vessel construction.

Key Features & Benefits:

• Triple Deoxidized Formula: Formulated with Aluminum, Titanium, and Zirconium to combine with oxygen, eliminating porosity and defects when welding on rusty, oily, or mill-scale surfaces.

• Radiography-Quality Welds: Produces clean, ductile, and defect-free weld joints that easily pass X-ray and ultrasonic testing in pressure applications.

• Smooth Arc & Copper Coating: High-purity copper coating prevents rust formation in storage, extends shelf life, and ensures smooth arc stability with low spatter.

• High Impact & Tensile Strength: Delivers strong mechanical properties suitable for low-temperature toughness and heavy-load structural joints.

• Wide Range of Applications: Essential for process piping, oil & gas pipelines, sheet metal work, structural repairs, boiler tubes, and automotive fabrications.
