Weldable Rebar coupler

Weldable Rebar coupler is a mechanical connection device used for splicing steel reinforcement bars through welding. Manufactured from high-quality structural steel with factory-prefabricated welding grooves, it allows two rebars to be welded to the sleeve either on-site or in the factory, forming a continuous force-transferring rigid joint. This product is suitable for all engineering scenarios permitted by the reinforcement welding operation specifications, particularly for large-diameter rebars, connections between different types of steel, and complex joint areas.

How to Connected

STEP 1 ：Rib Peeling: A specialized rib-peeling and thread-rolling machine is used to precisely remove the longitudinal and transverse ribs from the ends of the reinforcing bars, forming a smooth and regular cylindrical surface. This step eliminates interference from the ribs during subsequent rolling, ensuring a consistent base diameter.

STEP 2 ：Thread Rolling: The cylindrical section after rib peeling undergoes cold-rolling via thread-rolling wheels. Under plastic deformation, the metal fibers are redistributed and strengthened, forming continuous, dense, high-strength threads. This process does not involve metal cutting but rather enhances the metal's properties.

STEP 3 :Reba coupler Connection: The two reinforcing bars with processed threads are screwed into the sleeve. A specialized wrench is used to tighten them until the bar ends are firmly pressed against each other inside the sleeve, enabling the transfer of force.
