Learn More DetailsBulgaria’s strategic position as a logistical bridge between Europe and Asia has stimulated an expansion of industrial manufacturing, automotive parts fabrication, and infrastructural development. Heavy industrial clusters in Plovdiv-Trakia Economic Zone, Sofia, Devnya, and Ruse are experiencing an influx of automotive component factories and mechanical workshops requiring robust, reliable gas metal arc welding (GMAW / MIG) consumables. To reduce logistics costs and secure supply chain resilience, local metal manufacturers are upgrading from importing welding consumables to setting up localized, state-of-the-art CO2 Solid Welding Wire Production Lines.
Standard gas-shielded CO2 solid wires (such as SG2/SG3, conforming to EN ISO 14341 G3Si1/G4Si1 standards) are the backbone of this metallurgical expansion. With construction companies, railcar repair works in Ruse, and shipbuilding yards in Varna demanding premium welding wire, having local manufacturing capabilities using Beijing Orient Pengsheng technology ensures competitive pricing, swift delivery, and compliance with strict European Quality and CE standards.
Environmental standards in the European Union mandate minimal chemical discharge. Our mechanical descaling units integrated with industrial ultrasonic washing machines ensure chemical-free scale removal, making your operations compliant with the Bulgarian Executive Environment Agency (ExEA) regulations.
An in-depth look at our CO2 solid welding wire production process chain.
The manufacturing process begins with a raw wire rod (typically ER70S-6 or SG2 steel chemistry, 5.5mm diameter). The surface oxide scale must be completely removed. We provide a mechanical descaling system featuring high-velocity bending pulleys followed by belt-sanding or high-efficiency wire brushing. This eliminates acidic waste streams, reducing environmental permitting overheads for Bulgarian businesses. Next, an inline Ultrasonic Cleaning Machine uses hot water with minimal detergent to wash off remaining lubricants and iron powder before drawing.
Our drawing benches are engineered to reduce wire cross-section uniformly down to final sizes like 0.8mm, 1.0mm, 1.2mm, or 1.6mm. Unlike old-generation slip-type drawing machines, our Straight-Line Wire Drawing Line utilizes individual AC servo-motor drives controlled via Profinet/Ethernet IP networks. Each drawing block features a separate PID-controlled dancer arm system for active tension control. This prevents micro-slips and reduces structural deformation, avoiding the internal stresses that cause wire snapping or uneven feeding in robotic welding torches.
To prevent rust during storage and to ensure excellent electrical contact during high-speed feeding, a thin, uniform copper coating is chemically deposited on the steel wire surface. Our inline copper plating line consists of:
Acid Wash -> Rinsing -> Chemical Copper Plating -> Rinsing -> Neutralizing -> Hot Air Drying.
We precisely control the coating density to be between 0.15g/m² and 0.35g/m² through temperature and chemical concentration regulators. This guarantees optimal performance in manual and automated MIG/MAG setups across Plovdiv metal fabrications.
The final step involves rewinding the copper-plated wire from large take-up spools onto plastic (spool BS300/D300) or metal baskets (K300). The CE Certified Layer Winding Machine utilizes dual-axis servo systems: one for spool rotation and one for the traverse assembly. The traversing pitch is automatically adjusted to the measured wire diameter. This level of accuracy guarantees zero crossovers or overlapping loops, which is a major selling point for end-users operating robotic welding stations in Sofia’s automotive industry.
