LHA4C Side Control Gantry Type H Beam Submerged Arc Welding Machine

The attached photos were taken on a set of LHA4C Gantry H Beam Welding Machine exported to India by Wuxi JACK.  (Fig.1)

1.     Application of LHA4C H Beam Gantry Welding Machine in welding H Beam Production Process:

1)      For the H Beam with its max. web height of 1500mm, the LHA4C Gantry H Beam SAW Machine does not have counterpart in center control H Beam Gantry Welding Machine: The largest workpiece size in LHA4Z Gantry I Beam Welding Machine is 1200mm, and LHA5Z is 1800mm;

2)      On the other hand, in all the process step of H Beam production equipment, 1500mm is one of the standard indexes in terms of max. web height, and also the most used one, due to its medium size. For this specific model of LHA4C Gantry I Beam Submerged Arc Welding Machine, the corresponding suitable H Assembly machine is Z15, the H Beam Straightening Machine is HYJ800.

2.     Strong Points of LHAC Side Control H Beam Gantry Welding Machine in Operation:

Judging on the surface, as a side control (Operators stand at external side of H Beam at the outside of machine rail, please check below sketch), this series of automatic Gantry H Beam SAW Machine has the “drawback” of needing two operators to manage the SAW (Submerged arc welding) of two workpieces, instead of only one operator:

(Fig.2)

However, as a saying goes “Anything existing must be reasonable”, with such kind of arrangement in the LHAC Gantry H Beam Welding Machine, it has several merits, which is important for customer:

1)     Land Occupation of LHAC H Beam Gantry Welding Machine:

As explained before, for the same size of H Beam web height, LHAC gantry H Beam SAW machine is more compact than LHAZ in terms of machine size (10% less);

2)     Welding Quality Assurance in LHAC Gantry H Beam SAW Machine:

a)       With each operator takes care on each piece of H Beam welding, he or she does not need to distract attention from this H Beam to the other during the simultaneously two H Beam SAW process. Which means, the operator can focus on the welding of specific H Beam whole heartedly, and thus can deliver welded H Beam of high quality in greater probability from this H Beam Gantry Welding Machine;

b)      Anyway, as introduced in product category of these series of high quality Gantry I Beam Submerged Arc Welding machine (LHAZ, LHAC, LHC, LHT), submerged arc welding is the most important step for in H Beam production process technology, in terms of finished product quality control;  

3.     Working Process Management in LHAC Gantry H Beam Welding Machine:

Also, because two operators work at the same time, they can manage working process of this high efficiency gantry H Beam SAW machine easily and calmly:

1)      Cooperate and act as each other’s back up. When any one of the operators needs to leave working site in a short time during working of the LHAC H Beam Welding Machine, the other operator can substitute his or her job immediately;

2)      Monitor SAW process of the two H Beam in the gantry H Beam Welding Machine together. If one operator has an absent mind at certain time, the other operator can make up for the ignorance;

3)      If ever contingency or problem happens with the Gantry I Beam Welding Machine, they can deal with the condition without in a hurry.

4.     Interlock Operation in LHAC H Beam Gantry Welding Machine:

1)      On the other hand, with two operators operate on this LHAC automatic H Beam SAW machine together, synchronous work is very important. Otherwise, suppose such a situation, that one operator starts on welding process of one welding torch, while the other does not start on the other one…

2)      For this reason, in control system of this side control HA4C automated Gantry H Beam Welding Machine, there is interlock between the two welding stations in the machine. Which means, as in the above mentioned case, only two operators start the SAW welding power supplies together, can begin the process of gantry travel and SAW in the whole LHAC H Beam Gantry Welding Machine.
