The attached master picture (The first photo) is a set of Wuxi JACK designed and produced ZHJ18 model integrated function SAW welding mode, 3 in 1 I Beam Fabrication Machine. The photo was taken at front side, which is finished T Beam/ I Beam coming side of the machine.
1) ZHJ18 is the medium size model in ZHJ series 3 in 1 T Beam Welder Machine also for producing Welded I Beam, for producing welded T Beam/ I Beam of max. web height of 1,800mm height:
2) The erected welded I Beam fabricated from Wuxi JACK ZHJ18 machine, at Russian customer facility: (Fig.1)
ZHJ18 model does not take the largest share of application. The most extensive selected model is ZHJ15 model, because welded I Beam/ T Beam with web height up to 1,500mm is the most popular used size of raw material in steel structure construction, while I Beam and T Beam with web height of 1,800mm (Corresponding to ZHJ18 model) and 2,000mm (Corresponding to ZHJ20 model) are only for minority of large size jobs;
In the product section of “PHJ20 Symmetric and Asymmetric”, we discussed on major disparity between PHJ and ZHJ series 3 in 1 T Beam Welder Machine, in terms of workpiece/ operation (Flange and web alignment), as well as machine structure. Let us have a brief review that:
1) In PHJ series Integral function 3 in 1 I Beam Assembly Weld Straighten Machine, the alignment on flange with web are implemented with working mode of one side hydraulic drive, and the opposing side with manual handwheel:

2) Comparatively, in ZHJ series equipment, the T Beam and I Beam flange and web alignment are carried out in the manner of both sides in phase positioning and clamping, driven with hydraulic cylinders, and guided with moving horizontal guiding shafts:

1) Please check attached video of a Wuxi JACK ZHJ18 model 3 in 1 T Beam Welding Machine: In the video, the eccentric alignment rollers are still not installed, just their guiding shafts. We can see that there are 2 pairs of guiding shafts (At the upper location) for guiding web alignment rollers, and 2 pairs of guiding shafts (At the lower location) for guiding flange alignment rollers;
2) Driven with oil cylinders, these guiding shafts move synchronously toward each other in each pair. And can be imagined, with alignment rollers installed at the terminal of these guiding shafts, these alignment rollers will position and assemble the flange and web in phase automatically. This explains major difference in precise assembling implemented between Wuxi JACK ZHJ series and PHJ series 3 in 1 I Beam Welding Machine.
1. Integrated Running: The attached 2nd picture shows an instant of T Beam assembling/ welding/ straightening simultaneously carried out at a set of Wuxi JACK ZHJ18 model 3 in 1 T Beam Welder Machine. The three steps are implemented simultaneously in practical daily work, that we can only divide the three steps and make analysis on it during installation and validation process, as what is the case with the attached video:
Vertical view on commissioning moment of Wuxi JACK ZHJ18 model: (Fig.4)
Depending on thickness range of flange and web, there are 2 major types of welding mode:
1) SAW: Submerged arc welding, which takes over 90% of welding operation in T Beam and I Beam fabrication, for producing medium to thick plate I Beam and T Beam: (Fig.5)
2) CO2 Welding: Takes less than 10% application in steel structure welding, for fabricating thin plate workpieces, with high strength: (Fig.6)
The attached 3rd and 4th photos take welding seam and welding moment of SAW and CO2 respectively in this 3 in 1 I Beam Assembly Weld Straighten Machine;
3. Hydraulic Drive Manipulator: The attached 4h picture is the close distance shooting on machine hand (Hydraulic drive manipulator, or pulling rod boxes) deployed along input conveyor of the machine. They serve as preliminary fit up of flange and web during its feeding into the machine:
