Robotics and AI in Welding and Fabrication – Durban, a key industrial hub of South Africa, is undergoing a significant technological transformation. The city’s leading welding and fabrication companies are now shifting from traditional methods to highly sophisticated, AI-driven and robotic solutions. The reason? To meet international-grade metalwork standards and remain competitive in the global supply chain. This evolution marks a critical moment for Durban’s manufacturing and engineering sector, which is now embracing automation to achieve enhanced accuracy, faster turnaround times, and scalable operations. Earlier, welding and fabrication involved manual labor, inconsistent results, and slow project cycles. But the adoption of robotics and AI has introduced smarter, safer, and more cost-effective workflows that benefit not only manufacturers but also their global clients. This shift is creating new job roles, upskilling opportunities, and setting new benchmarks in South African industry quality.
