The D16 nitrided 2000×1000 3D flexible welding station is an industrial-grade precision welding fixture platform. It utilizes HT250 high-strength gray cast iron as its base material and undergoes professional gas nitriding treatment to form a surface nitrided layer with a hardness of HV600-650, providing excellent wear resistance, rust prevention, and resistance to weld slag adhesion. The platform dimensions are 2000mm×1000mm×200mm (length×width×height), equipped with a standard D16 hole system with a grid spacing of 50×50mm, providing five precision-machined working surfaces suitable for welding, assembly, and inspection of various small and medium-sized workpieces.
