H Steel Beam Production Line

Welding straightening machine is a special equipment that directly assembles, welds and corrects the wing plate and web plate of H-shaped steel. This advanced steel beam welder integrates multiple functions to optimize the production process.


The process that is traditionally completed by three equipment, such as assembling machine, gantry welding machine and straightening machine, is concentrated in one equipment, significantly improving production efficiency. This all-in-one steel beam welder reduces equipment costs, saves space, and conserves human and material resources and electricity. It is a highly efficient production equipment for H-shaped and T-shaped steel.


The equipment consists of welding assembly main machine, straightening auxiliary machine, pre-centering system, active roller table, passive roller table, flux recovery system, hydraulic system, electric control system, welding power supply, and other components, making it a comprehensive steel beam welder solution. As one of the leading auto welding machine manufacturers, Minghua is ready to offer solutions tailored to your needs.

Features of H beam production line

  • The main engine adopts three groups of wing plate and web center clamping mechanism to solve the web tail swing in use Phenomenon.

  • The positioning and pressing are all mechanical manual and hydraulic clamping, with fast speed and high precision.

  • Hydraulic system control valve adopts advanced superposition valve control, compact structure, easy maintenance, low failure rate

  • The main drive roller is controlled by frequency converter, and the workpiece conveying realizes stepless speed regulation, which makes its group efficiency higher.

  • Automatic spot welding function: Automatic spot welding system includes two sets of automatic spot welding mechanism and NB-500 inverter gas protection.Two sets of welding machines
