Product Overview

The Oerlikon Spezial E7016-H8 is a premium low-hydrogen, basic-coated electrode engineered for high-integrity welding of carbon and carbon-manganese steels. With a diameter of 3.2mm, this electrode delivers exceptional weld quality, superior mechanical properties, and reliable performance across structural, pressure vessel, and general fabrication applications where crack resistance and weld soundness are critical.

Key Features

• AWS Classification: E7016-H8 – meets stringent international standards for tensile strength and hydrogen control
• Low-Hydrogen Basic Coating – minimizes the risk of hydrogen-induced cracking (HIC) in the weld and heat-affected zone (HAZ)
• H8 Diffusible Hydrogen Rating – guarantees diffusible hydrogen content below 8 ml/100g of deposited weld metal, ideal for high-restraint and thick-section joints
• 3.2mm Diameter – suited for medium-to-heavy section welding, root and fill passes
• Smooth, Stable Arc – easy strike, low spatter, and self-releasing slag for minimal post-weld cleanup
• X-Ray Quality Welds – produces dense, porosity-free deposits suitable for radiographic inspection

Mechanical Properties

• Tensile Strength: ~490–620 MPa (70,000+ PSI class)
• Yield Strength: High yield point suitable for structural load-bearing applications
• Elongation: Excellent ductility for demanding service conditions
• Impact Toughness: Good notch toughness at sub-zero temperatures, suitable for critical structural work

Applications

• Structural steel fabrication (bridges, buildings, cranes)
• Pressure vessels and boiler construction
• Shipbuilding and offshore structures
• Pipeline and pipe fabrication welding
• Heavy equipment and machinery manufacturing
• General repair and maintenance welding requiring crack-resistant, high-strength joints

Recommended Base Metals

Suitable for welding carbon steel, carbon-manganese steel, and low-alloy steels commonly used in construction and industrial fabrication.

Welding Positions

Can be used in flat, horizontal, vertical, and overhead positions, depending on current settings and operator technique (verify against manufacturer datasheet for position-specific parameters).

Storage & Handling

As a low-hydrogen electrode, proper storage is essential to maintain H8 diffusible hydrogen performance:

• Store in a dry, controlled environment
• Use a holding oven (100–150°C) once opened
• Re-bake as per manufacturer guidelines if exposed to moisture
