The Extensive Use of H Beam Gantry Welding Machine in Industries

The General Purpose Application of H Beam Gantry Welding Machine

 

1. H Beam Gantry Welding Machine has the widest application range in the product group of H Beam Welding Machine. In certain respect, it is the default name of “Individual equipment for submerged arc welding”: When talking about “H Beam Gantry Welding Machine”, people refer to the type of large scale equipment for implementing large current SAW on large size working parts;
2. Not only producing H Beam I Beam T Beam for steel structure industry, H Beam Gantry Welding Machine is also widely used for fabricating other kinds of big workpieces which need long length welding, for example, lamp post, large diameter pipe, etc. This makes customers of Gantry Welding Machine come not only from Steel Structure Industry, but also Municipal Construction, Petroleum Pipeline, etc. This is the main difference between Gantry Welding Machine, and Open Structure H Beam Welding Machine: It is an universal and general purpose welding equipment;

Category of H Beam Gantry Welding Machine:

Compared with LHC and LHT H Beam Welding Machine, the uniqueness of LHA H Beam Gantry Welding Machine is its closed style machine frame, which gives confinement on available workpiece size, and corresponding variation of models for different workpiece size, as well as where should operator stand during working;
Based on structure and applied workpieces, H Beam Gantry Welding Machine can be classified into 3 types of:

1. LHAZ Center Control H Beam Gantry Welding Machine;
2. LHAC Lateral Control H Beam Gantry Welding Machine;
3. LHG / LHD Dedicated Design Gantry Welding Machine;


Let us have a short review on it one by one.

2. LHAC Side Control H Beam Gantry Welding Machine:

More >>

1. Definition on LHAC Side Control H Beam Gantry Welding Machine:

1) As you can find right hand photo of the LHAC H Beam Gantry Welding Machine, during working, operators stand at external sides of the H Beam supporting rack, beneath and inside the traveling main body of the machine;
2) Correspondingly, the orientation of the two arrays of workpiece racks is also different from that of the LHAZ;
3) In one set of LHAC side control H Beam Gantry Welding Machine, two operators need to work together for welding 2 pieces of workpieces at the same time;

4) Technical features of LHAC H Beam Gantry Welding Machine are same as LHAZ, in terms of welding technique (Large current SAW), productivity (2 pieces simultaneously), and material handling;
5) The difference is, in LHAC side control H Beam Gantry Welding Machine, there should be interlock in electric control system of the machine, so that the working in pace between the 2 operators is 100% guaranteed, and no wrong operation happened, which may bring negative effect to the Gantry Welding Machine.


2. Prons and Cons of LHAC Lateral Operating H Beam Gantry Welding Machine:
1) The first strong points of LHAC lateral operating H Beam Gantry Welding Machine is, compared with LHAZ, it occupies smaller workshop area. In other words, the equipment has compact overall dimension;
2) Besides, operators of the LHAC lateral operating H Beam Gantry Welding Machine do not have as stressful workload as operator of the LHAZ. During working, one operator takes care on SAW process of one working parts only, instead of two pieces as in the case of LHAZ center control;

3) Correspondingly, the weak point of LHAC lateral operating H Beam Gantry Welding Machine is its double of variable cost compared with LHAZ center management style.


3. Standard Models of LHAC Lateral Management H Beam Gantry Welding Machine:

There are 2 standard models in LHAC H Beam Gantry Welding Machine:
1) LHA4C: For producing H Beam and T Beam with web height up to 1500mm. This is the model with the biggest sell volume of H Beam Welding Machine, for used in standard model of HB1500 H Beam Production Line;
2) LHA5C: For producing H Beam and T Beam with web height up to 2000mm. This model is used in heavy duty HB1800 and HB2000 H Beam Production Line;

1. LHAZ Center Control H Beam Gantry Welding Machine:

More >>

1. Definition on LHAZ Center Control H Beam Gantry Welding Machine:

1) This is the earliest type of H Beam Welding Machine put to market, and is used in semi automatic H Beam Production Line. Or, in other words, LHA H Beam Gantry Welding Machine is used separately at customer site;
2) As you can find right hand photo of the LHAZ H Beam Gantry Welding Machine, during working, operator stands at middle position beneath traveling main body of machine, between the two arrays of H Beam supporting racks;

 

2. Prons and Cons of LHAZ Middle Operating H Beam Gantry Welding Machine:

1) So, there is only 1 operator necessary for operating and monitoring working process of 1 set of LHAZ H Beam Gantry Welding Machine. For this reason, you can imagine that labor intensity of operator for LHAZ is fairly intensive;
2) Compared with LHAC side managing H Beam Gantry Welding Machine, which has 2 operators for working on 1 set of equipment, the advantage of LHAZ is its labor saving, which reduces variable cost of customer;
3) The disadvantage of the LHAZ Center control H Beam Gantry Welding Machine is, for producing the same max. size of workpiece, LHAZ takes 10% wider workshop area than LHAC side control.

 

3. Technical Features of LHAZ H Beam Gantry Welding Machine:

1) There are 2 sets of welding torch in one set of LHA. So, one time running of the LHA H Beam Gantry Welding Machine can implement SAW welding on two pieces of H Beam and or T Beam at the same time;

2) Compared with LHC, the material handling in LHA H Beam Gantry Welding Machine is hard and toilful: Every piece of workpiece needs to be flipped 4 times for completing its 4 passes of welding seam with the help of traveling crane, this poses great challenge on operator safety, working pace, and workpiece protection during running of the LHA H Beam Gantry Welding Machine;
3) The welding technique in LHA H Beam Gantry Welding Machine is single arc, or twin arc submerged arc welding. This is true with LHC and LHT H Beam Welding Machine also. For detail, please check product of Advanced SAW Technology LHA Model H Beam Gantry Welding Machine.


4. Standard Models of LHAZ H Beam Gantry Welding Machine:
There are 3 standard models in LHAZ H Beam Gantry Welding Machine respectively:
1) LHA4Z: For producing small height H Beam and T Beam, with max. web height 1200mm;
2) LHA5Z: For producing medium height H Beam and T Beam, with max. web height 1800mm;
3) LHA55Z: For producing large height H Beam and T Beam, with max. web height 2000mm;
