H Beam Gantry Welding Machine from Wuxi JACK, Welding Wide Range of Workpiece for Customer!

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;

3. Below are sketches of three examples of working parts that can be manufactured with Gantry Welding Machine:   

1) Welding H Beam/ T Beam: Length 3m~ 15m, web height 200mm ~ 2000mm:

2) Lamp Post: Length 9m~ 16m, cross section diameter: 300mm ~ 2500mm:

3) Oil and Gas Pipeline: Length 15m, cross section diameter: 500mm ~ 1500mm:

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;

5. Technical Parameters of LHAZ H Beam Gantry Welding Machine:
Below are specifications of LHA4Z, LHA5Z, LHA55Z center control H Beam Gantry Welding Machine:

4. Technical Parameters of LHAC Lateral Management H Beam Gantry Welding Machine:

1. Definition on LHG / LHD Dedicated Design Gantry Welding Machine:

1) This series of Gantry Welding Machine belongs to special purpose welding equipment, or dedicated use: One design for one case of application. Unlike the LHA/ LHC/ LHT H Beam Welding Machine, that one time design can be replicated to numerous application cases;
2) This series of Gantry Welding Machine is for meeting the niche demand, from as small as for lab use, to as large as for carrying out SAW back welding on lamp post.

2. Technical Features of LHG/ LHD Dedicated Design Gantry Welding Machine:

1) Overall Dimension of the Gantry Welding Machine:

This series of Gantry Welding Machine has broad range of overall size, from as short as 1.6m, fitting for line of sight height of an adult people, to as high as 4m, which needs motor drive up and down movement of welding torch;

2) Welding Torch Degree of Freedom in the Gantry Welding Machine:

a) To fulfil the complicated welding process, such as taper, the welding torch in this series of Gantry Welding Machine has more control axis than that of the LHA/ LHC/ LHT H Beam Gantry Welding Machine;
b) Not only can the gantry travel along the 15m ~ 20m length rail, the welding torch can move leftward and rightward along horizontal beam of the gantry, but also the traveling carriage can move inside the entire box gantry frame along horizontal and vertical direction, under motor drive;
