Rebartec® Bar Weld is a coupler designed for projects where steel and reinforced concrete are used together. One side of the coupler is a butt left open for welding and the other side is upset threaded system coupler. With this method, transition from steel to reinforced concrete is provided by a coupler. When this coupler is used, the coupler is first welded to the steel area. Cold headed threaded reinforcement is rotated to coupler and the assembly is completed.

Welding of Couplers
Rebartec® Weldable Couplers offer the perfect solution for connecting the iron rod to a steel superstructure or individual assemblies. The fasteners have the same mechanical properties with Bar Weld of Rebartec® Standard Couplers and an inclined tip for welding.

Welded joints can be arc welded at the manufacturing workshop or in the work site. Some welding factors and welding design depend on the material to which the couplers are welded. Rebartec® recommends a qualified engineer to review all common design and data requirements, including the procedure for selection of welding filler, local rules and advises.

For reasons of applicability, there are normally two general arc welding processes used in construction sites and manufacturing workshops:
For reasons of applicability, there are normally two general arc welding processes used in construction sites and manufacturing workshops:
1-Manual metal arc welding (MMA) / (SMAW): Suitable for accessibility problems and / or welding conditions at construction site.

According to the dominant application codes Rebartec® Bar Weld Couplers don’t require pre-heating before welding. However, there are several factors that may require pre-heating. Therefore, carbon equivalent and thickness measurements of the material to which the coupler is welded are important. Rebartec® recommends you to follow the American Resource Association (AWS) Structural Source Code D1.1.

Operation sequence
Operation sequence
Before welding Rebartec® Bar Weld Couplers the local area must be cleaned or wire brushed and the plastic cover should be removed from the couplers. In the correct assembly, both surfaces should be aligned without any visible voids between the coupler and the material it is welded. The couplers should be welded in three symmetrical positions and then balanced to ensure proper alignment.
