ArcFlat Weld Tables were specifically designed to be bolted together so that the size and configuration of your weld table is virtually limitless. Each 2’x3’ weld block is guaranteed to be flat within .015”. To ensure that the entire multi-block table surface is also as flat as possible, a special assembly and bolting process is required. You can find more information about how the precision leveling bolt kit works to maintain flatness here:
Alternatively, ArcFlat weld blocks can be joined with standard 1/2" bolts; however, the ±0.0075” flatness rating can only be maintained across the entire surface of two adjoining weld blocks using the precision leveling bolt kit.
