SMART H BEAM ASSEMBLING MACHINE BZJ2000-S1 PLUS

What is a Beam Tack Welding Machine?

A beam tack welding machine is used to tack-weld two H-beams simultaneously using two welding torches positioned on either side. After steel plates are cut by CNC plasma or oxy-gas cutting machines, they are automatically assembled into H-beams by the tack welding machine through a hydraulic system and welding power source.

Why Choose the BZJ2000-S1 PLUS Intelligent H-Beam Tack Welding Machine?

The BZJ2000-S1 PLUS is a new-generation tack welding machine developed and improved by Bruco – Weldcom, based on comprehensive evaluations of previous models. This latest version features enhancements in both mechanical design and control technology to increase productivity and improve weld quality.

Key Advantages

• Compact machine body with rigid structure, logical layout, and flexible design. The main drive motor is neatly integrated inside the machine frame.

• The flange/web clamping system utilizes ball screws and hydraulic cylinders, offering firm clamping, wide working range, high stability, and precision.

• Integrated flange support cylinders help support beams with flanges longer than the web or deformed flanges, minimizing manual handling.

• User-friendly touch interface by KEYENCE with built-in SCADA and MES connectivity – no additional hardware required.

• High tack welding speed, ranging from 0.6 to 3 m/min.

Machine Configuration of BZJ2000-S1 PLUS

Main Components:

• Main machine body: upper beam, clamping system for web, flange and center, primary transmission & reducer, manual supports.

• Output roller table

• Input roller table

• Hydraulic system: 1 set (oil pump station, high-pressure hoses, hydraulic cylinders)

• Electrical control system: 1 set (control cabinet, cables)

• Automatic welding system: 2 Weldcom VMAG 500 or Megmeet Artsen CM350R power sources

Centering Clamp System:

• Beam flanges are centered by 4 pressing rollers; webs are centered by 8 rollers to ensure almost absolute accuracy (deviation < 1mm).

• Easy removal of 4 web clamping rollers allows for tack welding of small-size beams (as small as 160 mm web height).

• Smart, compact design allows for quick and accurate centering adjustments, even for off-center beams.

• Clamping movement is driven by a hydraulic motor with chain transmission, using ball screws and linear guides for smooth and precise operation with low noise.

• Additional auxiliary clamps ensure safe and accurate processing of large beams.

Pressing System:

• Large, robust guide rollers for hydraulic pressing cylinders ensure stable pressure and easy adjustments.

• Centerline alignment of pressing rollers guarantees clamping accuracy.

Welding Torch Assembly:

• Welding torches are positioned precisely between the pressing cylinder and main drive roller, ensuring accurate tack welds with no gaps between web and flange.

• The welding torch holder is firm and self-aligning, ensuring exact weld placement at the web-flange joint.

Drive System:

• The main drive motor is enclosed under the machine bed, saving workshop space and improving safety.

• Equipped with a 5.5 kW motor, the system supports loads up to 20 tons via reinforced rollers.

• Roller conveyors are solidly welded and built with thick, high-strength tubing for long-term durability.

Electrical Control System:

• Uses Yaskawa inverter for a compact control cabinet.

• Compact yet fully functional control panel with intuitive operation.

• PLC-controlled, enabling automatic centering, flexible weld length adjustment, and variable tack intervals.

Hydraulic System:

• 160L oil tank designed to be compact and space-saving for efficient workshop layout.
