B. Major Steps and Related Equipment in HB Series Welded H Beam Production Line:

Process Technology for producing welded H Beam: (Fig.5)

1. Step One: Plate Cutting:

With CNC-CG4000 CNC Strip Plate Cutting Machine:

1) Task: This step is for cutting carbon steel plate into strip plates, which will be used as flanges and web, in the subsequent steps of H Beam assembly and stitch welding/ SAW welding and straightening:

2) Wuxi JACK CNC Strip Plate Cutting Machine and cut off strip plates: (Fig.6)

2. Step Two: H Beam Fitting Up and Tack Welding with Welded H Beam Assembly Machine:

1) Task: This step is the first crucial work station at Welded H Beam Production Line:

2) T Beam Assembly: First one piece of flange and one piece of web are assembled into T Beam, and strengthened with CO₂ tack welding at the same time;

3) H Beam Assembly: Then, the T Beam is flipped 180°. The 2^nd piece of flange is loaded into H Beam Assembly Machine. And the T Beam is assembled and tack welded into H Beam:

4) Wuxi JACK Z20 model H Beam Assembly Machine works at steel structure customer workshop: (Fig.7)

3. Step Three: H Beam SAW (Submerged Arc Welding) with Welded H Beam Welding Machine:

1) Task: This is the central working zone of Welded H Beam Production Line. The assembled H Beam will be performed with 45° fillet SAW welding;

2) Welding Frequency: There are 4 passes of welding seam in one piece of H Beam. Consequently, there are 2 options of H Beam Welding Machine for customer choice:

a) Automatic Line: 4 sets of Wuxi JACK LHC model column structure H Beam Welding Machine, runs at export to East Europe fully automatic H Beam Production Line: (Fig.8)

b) Semi-automatic Line: 1 set of Wuxi JACK LHA or LHT model gantry frame H Beam Welding Machine: (Fig.9)

4. Step Four: H Beam Flange Straightening with Welded H Beam Straightening Machine:

1) Why Need: Flange of H Beam has upward bend deformation after SAW welding, because of heat input. H Beam Straightening Machine is for flattening such deformation:

2) Working theory indication on H Beam Straightening Machine: (Fig.10)

3)  Major Types of Wuxi JACK H Beam Straightening Machine:

Based on: Tensile strength/ thickness/ deformation position of H Beam flange, there are 3 major types of:

(1) Straightening force motor drive, for light to medium duty H Beam;

(2) Straightening force hydraulic oil cylinder drive, for heavy duty H Beam;

(3) Longitudinal deflection H Beam:

(1) Wuxi JACK HYJ800 motor drive H Beam Straightening Machine, for straightening H Beam with material Q235 carbon steel up to 40mm thickness: (Fig.11)

(2) Wuxi JACK YTJ80 hydraulic H Beam Straightening Machine, for straightening H Beam with material Q345 carbon steel up to 80mm thickness: (Fig.12)

(3) Wuxi JACK HJ300 longitudinal H Beam Straightening Machine, for straightening steel structure workpieces along horizontal body: (Fig.13)

5. Step Five: H Beam End Face Milling with H Beam End Face Milling Machine:

1) Task: This step is EOL (End of line) work station of welded H Beam Production Line. It polishes end faces of fabricated H Beam/ T Beam, removing burr and dirt, making end faces of workpieces gloss and clean:

2) Wuxi JACK DX1520 H Beam End Face Milling Machine works at steel structure facility: (Fig.14)

6. Material Transfer: The WIP (Work in process) working parts transfer among all the above work stations of welded H Beam Production Line, is implemented with Welded H Beam Turntable Machine.
