Insights into elevating weld designs to achieve successful hollow structural section connections. Hollow structural section (HSS) steel shapes allow for many geometric framing possibilities in structures with the benefit of aesthetic appeal. Maximizing the benefits of HSS sections in a design involves understanding the intricacies of various welding types for connections between members. Several considerations when designing welded HSS connections include the flexibility of the HSS connecting face, corner radius of square and rectangular HSS, and interior access for welding the tube. This article will explore weld selection and design considerations to ensure successful, cost-efficient HSS structures.
