Submerged Arc Welding (SAW) overlay cladding for wear-resistant steel plates has become the preferred solution in industrial wear-resistant applications due to its high efficiency, stability, and long service life. This process utilizes high-current submerged arc welding combined with high-hardness alloy wires (such as chromium carbide or high-manganese steel) to deposit a 5-30mm wear-resistant layer on a mild steel base plate, achieving a hardness of HRC50+, significantly enhancing abrasion resistance.
The automated production mode enables continuous overlay welding, with a 3-5 times higher deposition rate than manual welding, greatly reducing production time. The flux layer effectively shields the molten pool from air, ensuring dense, defect-free cladding layers. Additionally, the "low-carbon base + wear-resistant overlay" composite design reduces material costs while minimizing equipment weight.
This technology is widely used in harsh working conditions, such as mine crusher liners, metallurgical rollers, and coal mill components in power plants. With its high cost-performance and reliability, SAW overlay cladding helps enterprises extend equipment lifespan, reduce downtime, and achieve cost-effective performance optimization.
