ZHJ8018 Medium Size Three in One H Beam Fabrication Machine

The attached master picture (The first photo) is a set of ZHJ8018 model 3 in 1 integrated function SAW H Beam Welding Machine (SAW T Beam Welding Machine).

1. Application of ZHJ8018 H Beam Assembly Weld Straighten Machine:

1) Application Feature: ZHJ8018 is the medium size in ZHJ series Welding H Beam Fabrication Machine, but not takes the largest share of application. The most extensive selected model is ZHJ8015 H Beam Welding Machine (Also T Beam welder) of previous product section, because welding H Beam/ T Beam with web height up to 1,500mm is the most popular used size of raw material in steel structure construction, while 1,800mm and 2,000mm are only for minority of large size jobs;

2) In the product section of “PHJ20 Symmetric and Asymmetric 3 in 1 H Beam Fabrication Machine”, we discussed major disparity between PHJ and ZHJ T Beam welder, in terms of workpiece/ operation (Flange/web alignment)/machine structure. Let’s have a review, that in PHJ series Integral function H Beam Fabrication Machine, the flange alignment and web alignment are made with working mode of one side hydraulic driving, the opposing side manual handwheel;

3) Comparatively, in ZHJ series H Beam Welding Machine (T Beam Welding Machine), the flange alignment and web alignment are realized in the manner of both sides in phase positioning and clamping, driven with hydraulic cylinders, and guided with moving horizontal guiding shafts;

4) Please check attached video of a ZHJ8018 model 3 in 1 H Beam Fabrication Machine: In the video, the 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;

5) 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. This explains major difference in precise assembling happened between ZHJ series Welding H Beam Fabrication Machine and PHJ series H Beam Assembly Weld Straighten machine.

2. Welding Operation of ZHJ8018 Model 3 in 1 H Beam Fabrication Machine:

1) The attached 2^nd picture shows an instant of assembling/welding/straightening simultaneously happened at a set of ZHJ8018 model 3 in 1 SAW H Beam Welding Machine (SAW T Beam Welding 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;

2) As mentioned in the previous product section of ZHJ8015 Welding H Beam Fabrication Machine, that both SAW (Most majority) and CO₂ (Minority) welding can be carried out in this H Beam Welding Machine (T Beam Welding Machine). The attached 3^rd and 4^th photos take welding seam and welding moment of SAW and CO₂ respectively in this T Beam welder (H Beam Fabrication Machine);

3) The attached 5^th picture is the close distance shooting on machine hand (Manipulator) deployed along input conveyor of the Welding H Beam Fabrication Machine. They serve as preliminary fit up of flange and web.
