Topwell's submerged arc welding (SAW) system comprises two specialized series, engineered to address both heavy industrial thick-plate welding and the challenges associated with more precise energy management in thin-plate and nickel-based alloys welding applications. These systems are suitable for the fabrication of corrosion-resistant pressure vessels, wind power generation components, H-shaped steel, and pipeline construction.
                    With arc voltage feedback technology, Topwell’s SAW system ensures stable arc performance with minimal operator involvement, delivering consistent and repeatable weld results for critical applications across a broad range of material thicknesses and long-seam welding requirements.
Topwell’s SAW systems support seamless automation with versatile IoT interfaces, enabling users to unlock advanced capabilities and enhance flexibility in modern industrial manufacturing.
Advanced Features and Benefits
                        Precision Energy Control for Thin Plates and Nickle-based Alloy Welding
                    In constant voltage mode, welding current is precisely regulated to support high-precision welding processes. This allows for the use of welding wires as fine as 1.2mm, producing high-integrity welds on thin-gauge sheet metal. The system also delivers superior performance in welding nickel-based alloys, maintaining stability even at elevated temperatures and providing exceptional oxidation resistance. Through accurate control of linear heat input, the heat-affected zone is minimized, thereby reducing distortion and mitigating the risk of cracking. 
Hardfacing with High Deposition and Aesthetic Formation
                    
                                    • Produces consistent, high-strength weld seams;
• Attains 60–80% deposition efficiency for material savings;
• Avoids hydrogen cracking and porosity formation;
• Decreases grinding and eliminates extra passes.
Ready for IoT Connection
                    Versatile IoT interfaces, including communication, sensor, user interaction and power supply interfaces, allows unlimited possibility of interconnections, so as to meet the needs of modern industrial production.
