Features

• These H-beam welding lines are already widely used in the steel structure industry. More than 800 heavy-duty lines have been supplied to manufacturers in China, and nearly 100 have been exported to countries such as Iran, Ukraine, Vietnam, South Korea, and India.
• The production flow is arranged in a well-coordinated way, so the welding line runs more smoothly from one stage to the next. This layout makes automatic production easier to achieve, and in normal operation, overhead crane support is only required during assembly and final unloading.
• Travel and conveying speeds are shown digitally. This makes operation easier for workers and helps improve production control and processing consistency.
• The movable 180° hydraulic flipper can travel along rails, so flipping is not limited to one fixed position. Hydraulic operation also reduces the impact on the support structure during flipping, which improves stability and safety.
• The cantilever type structural steel beam welding system is equipped with a digital speed display, which makes the welding speed easier to check and adjust during operation. Its dual-axis dual-drive traveling system, combined with mechanical and pneumatic seam tracking, helps the welding head move more steadily along the seam and supports more consistent welding quality.
• The 60° hydraulic flipping system can be positioned at any angle from 0° to 60°. This design is suitable not only for standard symmetrical H-beams, but also for asymmetric H-beams that require non-45° boat-position welding.
