Sawyer Tackless Internal Welding Clamps are custom built to accommodate 2” to 6” pipe and tube with custom wall thickness. The Tackless Internal Clamp is designed for automatic welding but can be used with most flange-to-pipe or pup to-pup applications. A Quick Release Nut allows the clamp to be easily released from its position once the weld is complete. The replaceable Copper Backing prevents weld spatter.
