You're a construction component manufacturer or precast plant, struggling to meet tight deadlines for truss production. Manual welding is slow, inconsistent, and labor-intensive, while older machines lack the speed and precision you need. What you need is a smart, fully automated solution that delivers quality, speed, and reliability. That's where this steel bar truss weiding equipment comes in.
-
SGHJ-IV Reinforced Steel Truss Welding Production Line (Four Servo Swing Arm Style) is a versatile equipment developed by our company's R&D team after years of effort. It combines the latest truss technology from abroad with comprehensive technical improvements and upgrades. In addition to producing regular angle trusses and right angle trusses, customers can choose to install components for the production of detachable mold truss floor plates (currently supports square tube connectors, T-shaped connectors, and seven-bar truss reinforcement), allowing for multiple applications, enriching their own products, and increasing market share.

Common Faults & Quick Solutions
Welding Quality Issues
Symptoms: Weak welds, uneven heat, or burn-through.
Causes: Incorrect current settings, dirty electrodes, or misaligned parts.
Solutions: Adjust welding parameters based on rebar size; clean or replace electrodes; check and calibrate the alignment system.
Programming & Control Errors
Symptoms: Truss dimensions are incorrect, or the machine stops mid-cycle.
Causes: Faulty PLC programming, sensor calibration drift, or power supply fluctuations.
Solutions: Re-upload and verify the program; calibrate sensors; install a voltage stabilizer.
Mechanical Jamming or Misalignment
Symptoms: Rebar feeds unevenly, or the truss drifts during production.
Causes: Worn rollers, debris in the track, or misaligned guides.
Solutions: Clean and lubricate the track; inspect and replace worn rollers; realign the guide system.
