4. Technical features of ZHJ8020 Model 3 in 1 H Beam Fabrication Machine:

As can be check from attached pictures:

1) Assembly Unit in ZHJ8020 H Beam Assembly Welding Straightening Integral Machine:

In this integrated function H Beam Welding Machine:

a) The first step is rough positioning web and flange, by means of 3 sets of yellow color manipulators (pulling rod system), deployed along input conveyor of the Vertical I H Beam Welder. See below:

Hydraulic manipulators in Wuxi JACK 3 in 1 H Beam Fabrication Machine:  (Fig.3)

b) The second step is precisely positioning web and flange by means of 6 groups of alignment rollers, installed at mechanical main frame central working unit of the Pull Through I H Beam Welder. The T Beam and H beam is assembled into shape;

2) Welding in ZHJ8020 Integrated function H Beam Welding Machine:

a) ZHJ8020 H Beam Assembly Welding Straightening Integral Machine adopts with Single Arc or Twin Arc SAW (Submerged arc welding);

b) The welding power supply can be Chinese brand or U.S. Lincoln;

3) Straightening Operation in Wuxi JACK ZHJ8020 3 in 1 H Beam Fabrication Machine:
