The 3D welding table is a core tooling for industrial welding operations. Made of high-grade cast steel by integral casting, it undergoes aging treatment to eliminate stress, with precision up to 0.02-0.05mm. Its surface is densely covered with standard positioning holes and T-slots, enabling quick splicing and positioning of workpieces, adapting to various welding scenarios, reducing debugging time, improving welding precision. It is wear-resistant, anti-deformation, with long quality guarantee and strong adaptability, widely used in machinery, automobile, steel structure and other foreign trade export fields.
