    1. Structure character
  • Appearance see below picturePHJ15 H-beam Assembly-Welding-Straightening Integrating machine is an advanced and high efficiency equipment for welding H-beam production, integrating precision assembly, stable SAW welding, flange deformation straightening and welding of H-beam together. It has merits of compact structure, small area occupying, high automatic and high productivity. It mainly consists of assembly unit、welding unit、straightening unit、conveyor、hydraulic system and electrical control system, etc.2.1 Assembly unit:

    There are 3 sets of manipulator among input conveyors of the equipment, for roughaligning and positioning of flange and web. When sheets are hoisted onto the equipment, these manipulators can support the sheets and align them, preventing the sheets from dumping, making operation safe and reliable.

    There are 2 sets of positioning units for flange and web each, with the positioning style of both sides are hydraulic cylinder( not one side lead-screw, the other side hydraulic cylinder), making accurate positioning of the work-piece.

    The lead-screw positioning units(2 for flange, 2 for web) are joint together thru coupling shaft of reducer, guaranteeing in-phase working of the units, as well as simple and quick adjustment for different size of H-beam.

    After web and flange are sent into the equipment, the tail aligning unit will be raised

    automatically, making sure alignment of face of flanges and web.

    2.2 Welding unit

    2 sets of U.S. LINCOLN DC-1000 SAW system(or china brand 1000A power source) welding power source.

    2 sets of automatic flux recycling system are used for conveying flux to the welding seam and screening and recycling un-sintered flux by way of the suction hole at the rear side of torch, and sucking the flux back into flux barrel for re-use.


    2.3 Straightening unit:

    Deformation happens at the flanges post welding. For this reason, 1 set of flange straightening unit is equiped at the output side of the equipment. It is mechanic down-stroke style, of strong force and easy control.

    Thickness of flange that can be straightened see below table(tensile strength σb≈345MPa)

    Flange thickness


    6~12 12~18


    18~22 22~26




    Flange width


    200~800 450~800 560~800 650~800 700~800


    Thickness of flange that can be straightened see below table(tensile strength σb≈235MPa)

After welding, one side of web will be subjected to heat input, making H-beam expanding and bending upward. For this reason, 2 sets of elevating conveyor are used for supporting H-beam.

The equipment has the same speed for assembly、welding and straightening which is VF controlled and displayed in digit, adapting to manufacture of H-beam of various specification.
