Rebar Welding and Auxiliary Machines for the Site

Why Rebar Welding and Auxiliary Machines Matter

On a modern rebar processing site, cutting and bending are only part of the story. To deliver complete fabricated rebar assemblies, you also need reliable welding and auxiliary equipment. Gongda, based in Hefei, Anhui, China, offers a range of machines that complement our CNC benders and shears, helping you handle joints, threads, and custom shapes efficiently.

CO2 MIG Welding for Strong, Consistent Joints

For on-site or workshop welding of rebar and steel structures, the Gongda NB-350 and NB-500 CO2 MIG welding machines provide dependable performance. Both models feature digital DSP control, which ensures stable arc and consistent weld quality, even for less experienced operators. The NB-350 (350 A output) is ideal for light to medium fabrication, while the NB-500 (500 A output) handles heavier sections and high-duty cycles. They are suitable for carbon and stainless steel, making them versatile for various construction and fabrication tasks.

Thread Rolling and Other Auxiliary Equipment

Mechanical splices are a common alternative to lap welding in rebar connections. The Gongda HGS-40 rebar thread rolling machine rolls threads onto 14–40 mm bars, producing precise threads for couplers. This speeds up on-site assembly and reduces rebar congestion. In addition, our range includes spring making machines and band saws, which help with producing custom reinforcement elements and cutting bars to length. Together, these auxiliary machines form a complete rebar processing line, from straightening and cutting to bending, threading, and welding.

When planning your equipment set, consider your typical rebar diameters, production volume, and the types of connections you use. Our team can help you select the right combination of Gongda machines to match your workflow. Contact us via WhatsApp or email for a tailored quote and more details.
