LHA series Gantry type H Beam Submerged Arc Welding Equipment has wide application in steel structure industry. The attached photos show various sizes and configurations of such LHA models H Beam Welding Machine put into use at customer site and Wuxi JACK facility. It is sketch is as below: (Fig.1)
The LHA Gantry type H Beam Welding Machine is a kind of fully automatic I Beam SAW Machine (Submerged arc welding), integrating manipulation of below into one single set of equipment:
1) SAW Main Machine --- By way of machine operating panel;
2) Two sets of SAW power supply --- By way of its own control console and operating panel of the LHA model Gantry type I Beam Welding Machine;
3) Two sets of flux recovery and recycling unit--- By way of operating panel of this LHA model Gantry type I Beam SAW Machine;
4) Two sets of SAW wire feeder --- By way of operating panel of this LHA series Gantry type H Beam Welding Machine;
5) Two sets of arc tracing unit --- Mechanical type, no need to have manual manipulation during SAW welding in the LHA H Beam Welding Machine;
Into a convenient and easy operation. One operator can manage all these working cells.
The abovementioned manipulation of all function units is realized under the condition of, these components are deployed at different specific sections inside this large overall dimension H Beam Submerged Arc Welding Equipment:
1) SAW power supplies are put on the workshop floor alongside the long parallel traveling rails, in fixed manner;
2) Together with its hoppers, flux recovery and recycling units are put on the top side of beam of the gantry, and move along together with gantry moving during welding process of the H Beam Welding Machine;
3) Wire feeders and arc tracing units are assembled with SAW welding torch, composing into a complete set of SAW welding unit, which is fit on the transverse moving carriage of this LHA model gantry type I Beam SAW Machine. And each set of the carriage is installed on the beam of the gantry frame, at its front side.
To give a clear introduction, please check below picture: (Fig.2)
1) Control of this LHA Gantry type H Beam Submerged Arc Welding Equipment (also LHC and LHT) is realized with “One Button Starting on and Shutting off the entire H Beam Welding Machine”;
2) Which means, with the “WELDING ON” button being pressed on the operating panel of this LHA model H Beam Welding Machine, the machine itself and all the above-mentioned auxiliary units will be started on for working together, or shut off for break together. Please check attached sketch on machine operating panel of the LHA Gantry type H Beam Welding Machine exported to Russia: (Fig.3)
3) Same as LHT series I Beam Gantry Welding Machine, control board of LHA Gantry type I Beam Welding Machine is put on bed of gantry frame, at its lateral side. Please check below picture. Such arrangement has advantage of concise and short distance cable routing in the entire Gantry type I Beam SAW Machine, as well as playing as counter weight to give double insurance against the gantry frame from toppling down (although this is very low probability): (Fig.4)
a) For the other kind of common used H Beam Welding Machine besides LHA and LHT: The column structure LHC model I Beam SAW Machine, please check product section of “LHC Column type H Beam Submerged Arc Welding Equipment”;
b) For understanding on specific model of LHA models Gantry type I Beam Welding Machine as an example, please check product section (Or other section) of “4m Rail Span LHA4Z Automatic I Beam Gantry Welding Machine”.
