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

As can be check from attached pictures:

1) H Beam Assembly in ZHJ8020 Vertical H Beam Welder:

In this machine:

a) The first step is rough positioning web and flange, by means of 3 sets of yellow color hydraulic drive manipulators (pulling rod system), deployed along input conveyor roller tables of the machine. See below: (Fig.3)

b) The second step is precise positioning web and flange by means of the 6 pairs of alignment rollers, installed at main frame central working unit of the machine.

In this way, T Beam /H beam is assembled into shape;

2) H Beam Welding in ZHJ8020 Pull Through H Beam Welder:

a)  The 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, of 1000A ~ 1250A output welding power supplies;

3) Straightening Unit in ZHJ8020 Model 3 in 1 H Beam Fabrication Machine:

H Beam flange straightening unit is installed at outlet of machine main frame, right following assembly and welding units. It straightens on the welded flange with the downward straightening rollers; See below: (Fig.4)

4) Application of the ZHJ8020 Model Vertical H Beam Welder:

ZHJ series machine has bigger market share than PHJ series in Chinese Steel Structure industry. It takes around over 60% selling volume.
