An H Beam Assembly Machine is a specialized equipment used to position, align, and tack-weld the three components of an H-beam—web plate (the vertical center section) and two flange plates (the horizontal top and bottom sections)—into a complete H-shaped section prior to main welding. It ensures accurate centering and consistent gap control, providing properly assembled beams for downstream submerged arc welding (SAW) machines.

The H Beam Welding Machine is available in two configurations: gantry gate move type and double cantilever move type, both driven by AC motors with R-series worm reducers. The system features an arc guide frame head for mechanical tracking (up/down and left/right), ensuring precise torch positioning. Welding speed is adjustable from 0.15 to 1.5 m/min, with imported frequency converters enabling stepless speed control, high accuracy, and constant torque output. Electrical control includes a main cabinet and remote operation box for flexible operation. The machine supports simultaneous welding of two workpieces at once, significantly improving production efficiency.

The H-beam welding machine is an automatic system designed for high-efficiency fabrication of steel H-beams. It is available in two configurations: gantry type and double cantilever type, both driven by an AC motor with R-series worm reducer.
Welding speed is adjustable from 0.15 to 1.5 m/min via an imported frequency converter, enabling stepless speed control with high accuracy and constant torque. The arc guide frame features mechanical up/down and left/right tracking for precise torch positioning along the weld joint.
Control is managed through a main cabinet and a convenient remote operation box. The machine is capable of welding two workpieces simultaneously in one pass, significantly boosting productivity.
Ideal for steel structure fabrication, bridge building, and heavy machinery manufacturing.

The HYJ-800 H Beam Straightening Machine is a specialized equipment designed for correcting flange distortion and side bending of H-shaped steel beams after welding. It is an essential component in H-beam production lines, ensuring finished products meet dimensional accuracy and straightness requirements.

The YTJ-60A and YTJ-80A are compact, high-performance H-beam straightening machines designed for correcting flange distortion and side bending of small to medium-sized H-shaped steel beams after welding. These models are ideal for light to medium-duty fabrication workshops where precision, reliability, and cost-effectiveness are key priorities.

The machine features a stress-relieved integral frame, CNC-machined for high strength and rigidity. Upper roller is 35CrMo (heat-treated, wear-resistant); main transmission roller is 40Cr forged (quenched and ground for precision). Geared motor drives continuous flange straightening. Separate control and operation boxes enable convenient handling. Optional small pressing roller expands straightening range for various flange sizes.

The 3-in-1 H Beam Welding Machine features a patent-protected heavy-duty assembly host with automatic web/flange centering for high precision and efficiency. The independent welding gun mechanism enables flexible height, horizontal, and angle adjustments for quality welds. Its unique correction unit uses two active wheels without obstructing operator view. The system offers versatile use—assembly host can work alone as a welder or combine with the correction unit for full assembly and welding. The correction unit can also be modified into a small straightening machine, adding extra value.

1.Introduction for Horizontal H beam line:
Horizontal h beam welding line includes Horizontal H beam assembly machine,Horizontal H beam welding machine,tilting machine and transmission roller,its most suitable big quantity light duty h beam manufacturing,H beam manufacturing speed is 1.2-1.5 times comparing to conventional h beam welding line.
Technical functions:

As a highly automated H-beam production line, this system is designed with a key objective: minimizing the use of overhead cranes. By employing automatic machines such as roller conveyors, turning machines, and transfer conveyors to handle the conveying, turning, and moving of H-beams during the welding process, the line significantly improves production efficiency and reduces manual intervention.

H beam Shot blasting machine is primarily for shot-blasting of steel structural parts, aluminum profiles,steel sheets and steel billets to remove the rusty spot, rusty layer and scale cinder on steel to obtain a uniform, smooth and glossy metal surface allowing improved coating quality and higher anti-corrosion performance. Shot blasting machine To ensure the high shot-blasting performance and extend the service of rollers, a high-chromium grinding-resistant sheath is installed on the room rollers to extend its service life by scores of times,Automatic H beam Shot blasting machine.
