Modular Welding Table System consists of welding tables with grid pattern of system holes and standard reusable accessories. Like playing building block or magic cube, you can freely build up a set of welding fixture in short time using this system. Comparing with traditional dedicated fixtures, this system has advantages of high flexibility, high precision, little storage space requirement, time saving and reduced cost. This system was first used for fixturing prototypes to production or products of little production but with frequently changed design. Now this system is widely used for fixturing weldments as frame structure , vehicle, railway track, construction, electronics etc.
