What is a Beam Tack Welding Machine?

Beam Tack Welding Machine is used to tack weld 2 beams at the same time using 2 welding torches on both sides. After the steel is cut into sheets from a cnc plasma cutting machine or cnc oxy-gas cutting machine, the sheets are tack welded through an automatic beam tack welding machine into an H beam using a hydraulic system and welding source.

Reasons to Choose the Smart H Beam Tack Welding Machine BZJ2000-S1 PLUS

Smart H Beam Tack Welding Machine BZJ2000-S1 Plus is a new generation of tack welding machines researched and improved by Bruco – Weldcom based on the evaluation of the performance of older generations of tack welding machines to bring improvements in both mechanical structure and technology to enhance productivity and product quality for beam tacking work.

• Compact machine body, sturdy, reasonable structure, and flexible layout, with the main roller motor neatly housed within the machine body
• The wing/waist clamp of the main machine body uses lead screws, and the motor is hydraulic, ensuring stable, precise operation with a large clamping force and wide clamping range
• Integrated with a cylinder to support the beam wing for beams with longer wings than the waist or bent wings, minimizing operational effort
• Uses a user-friendly touch interface from KEYENCE with the ability to connect to SCADA and MES systems without additional equipment
• High tacking speed, can reach from 0.6 – 3 m/min

Structure of the Smart H Beam Tack Welding Machine BZJ2000-S1 PLUS

Main components of the BZJ2000-S1 Plus include:

• Main machine: main body, upper beam, waist, wing, and center clamping device, main drive and reduction gear, manual support device)
• Output roller
• Input roller
• Hydraulic system: 1 set including oil pump station, high-pressure pipe, hydraulic cylinder
• Electrical control system: 1 set including control cabinet, control cable
• Automatic welding system: 2 Weldcom VMAG 500 or Megmeet Artsen CM350R welding sources

Centering Clamp:

Centered by 4 pressure rollers for the wings and 8 rollers for the waist, ensuring almost absolute accuracy (error only <<1mm ).

• Can easily remove 04 waist clamping rollers when tacking small-sized beams (can tack beams with a small waist plate of 160mm)
• Smart, compact design allows for quick, precise eccentric beam welding adjustments
• Hydraulic motor-driven mechanism combined with chain, smooth and precise lead screw and slide rail movement (noise reduction)
• Additional auxiliary clamp for processing large beams to ensure accuracy and safety

Compression Cylinder:

• The compression cylinder guide wheel is designed to be large, strong, stable, and easy to adjust
• The compression roller is always centered, ensuring accuracy

Tack Welding Torch Mechanism:

• The tack welding torch mechanism is designed right at the compression point between the compression cylinder and the main roller shaft, ensuring very precise tacking without gaps between the waist and wing plates
• The welding torch clamp head is sturdy and self-adjusting, ensuring the tack weld is always precise at the exact corner between the waist and wing of the beam.

Drive Mechanism:

The main drive motor is neatly housed under the machine with a protective cover, saving workshop space and ensuring operational safety.

• Uses a 5.5kW main motor with a compact machine body design, saving workshop space
• The load-bearing capacity of the motor and roller is up to 20 tons
• The roller conveyor is securely welded directly
• Uses thicker and harder pipes

Electrical Cabinet and Control Unit:

• The machine uses Yaskawa inverters, making the electrical cabinet more compact than conventional machines
• The control panel is compact yet fully functional and easy to use
• Controlled by PLC with flexible automatic control programs, ensuring automatic waist centering, flexible adjustment of tack weld length and skip welds

Hydraulic System:

Compact oil tank with a capacity of 160l, saving workshop space.
