Metallurgical & Tribological Analysis

Self-Shielded Flux Cored Arc Welding (FCAW-S) Technology

The Physical Chemistry of Gasless Open Arc Welding Wires

In industrial wear management, Self-Shielded Flux Cored Arc Welding (FCAW-S), widely referred to as open arc welding, is a vital technological pathway. Unlike gas-shielded processes (FCAW-G), gasless open-arc wires rely entirely on the chemical composition within their flux core to form a localized shielding atmosphere. Highly active deoxidizers and denitriders such as Aluminum (Al), Magnesium (Mg), and Titanium (Ti) are integrated into the core. During arc plasma generation, these elements immediately react with oxygen and nitrogen drawn from the surrounding ambient air to form dense oxides and nitrides, which quickly float into the slag layer. This in-situ chemical barrier protects the weld pool from porosity and ensures a high-density, crack-free, hard deposit.

Tangshan Runxing Machinery’s proprietary formulations utilize precise ratios of active agents. This configuration maintains arc stability and reduces spatter, ensuring that the deposit exhibits high volumetric density. The primary metallurgical structure yields a matrix dense with primary M7C3 Chromium Carbides, achieving hardness levels between 58 and 65 HRC.

Microstructure Engineering: Eutectic Matrix & Primary Carbides

The durability of an overlay plate is determined by its microstructure, not just its surface hardness. The wear-resistant layer of Runxing's Chromium Carbide Overlay (CCO) plates comprises primary carbides ($Cr_7C_3$) distributed within a carbon-saturated eutectic austenite matrix. These primary carbides form as hexagonal prisms oriented perpendicular to the wear surface. This microstructural arrangement withstands severe sliding wear and high-stress grinding abrasion.

Our ongoing partnership with research institutes (such as Tangshan University) allows us to analyze crystallization behavior under varying solidification rates. High cooling rates during the surfacing process prevent carbide coarsening. Finer, well-distributed carbides reduce micro-cracking and prevent macro-spalling under impact conditions.

Innovative Development

Technology Roadmap & Future Outlook

Complex Multicomponent Carbides

Traditional chromium-iron wear systems face degradation in temperatures above 450°C. Our technological roadmap includes developing multicomponent carbide alloys containing Niobium (Nb), Tungsten (W), Titanium (Ti), and Vanadium (V). These elements form secondary MC/M2C carbides, ensuring reliable performance in high-temperature environments (up to 750°C).

Clean Hardfacing Wires

Environmental compliance is a priority for modern industrial operations. We are engineering self-shielded wires that reduce hexavalent chromium (Cr-VI) emissions in welding fumes by up to 40%. This is achieved by altering the slag-forming system to capture particulates before they enter the workshop atmosphere.

Submicron & Nano-Structure Alloys

By refining the eutectic spacing to a submicron scale, our future alloy systems will provide higher fracture toughness without sacrificing abrasion resistance. This microstructural advancement prevents crack propagation, making CCO plates suitable for high-impact applications in heavy mining.

Questions & Technical Support

Frequently Asked Questions (FAQ)

Q1: What are the primary advantages of Self-Shielded Flux Cored Arc Welding (FCAW-S) over Gas-Shielded methods?

FCAW-S does not require an external shielding gas supply, making it suitable for outdoor applications and onsite repairs where wind might disrupt gas coverage. The flux core contains active deoxidizers and denitriders that protect the weld pool, ensuring high-quality deposits in challenging conditions.

Q2: How does Tangshan Runxing ensure the bonding quality of its Bimetallic CCO Plates?

We use proprietary weld deposition techniques to manage dilution rates between the backing steel and the hardfacing overlay. All plates undergo ultrasonic testing to verify bond integrity, preventing delamination under impact loading.

Q3: Can these CCO plates be cut, formed, or welded onsite?

Yes, our CCO plates can be cold-formed or rolled according to design specifications. They can be cut using plasma arc processes or high-pressure waterjets. Welding can be performed on the structural backing plate using standard structural low-hydrogen electrodes.
