Why do You Need a set of Open Structure H Beam Welding Machine?

The Working Mode of H Beam Welding Machine

1. Applicable Workpiece and Welding Technique Adopted in H Beam Welding Machine:

1) T Beam and H Beam are large size and heavy weight working parts made of carbon steel. The common weight is in the range of 5Ton to 10Ton, with the max. up to 20Ton, in the thickness range of 6mm to 40mm. These are characteristics of workpieces processed in H Beam Welding Machine and H Beam Production Line;

3. Mechanical Structure of Open Structure H Beam Welding Machine:

1) Welding technology mentioned above is the same for all structures of H Beam Welding Machine. The variation in its machine body is originated based on application site: Automatic or semi automatic H Beam Production Line, the size of workpiece, which mainly differs based on H Beam web height, and arrangement of operator during work of the H Beam Welding Machine;
2) There are three types mechanical structure of H Beam Welding Machine in use: LHC column type, LHT T frame, and LHA Gantry H Beam Welding Machine;
3) In this page we will focus on the open structure H Beam Welding Machine: The LHT model T frame, and LHC model column structure H Beam Welding Machine; For introduction on LHA model gantry frame, please check product page “Gantry Frame H Beam Welding Machine”.

Welding Seam Tracing Unit in H Beam Welding Machine:

 

What is the Importance of SAW Seam Tracer for Performance of H Beam Welding Machine?

 

1. Welding seam tracer plays key role in determining welding quality of H Beam Welding Machine. This is specifically reflected in formation of welding seam on working parts:

1) During submerged arc welding working process of the H Beam Welding Machine, suppose welding torch deflects away from its proper target position, and could not keep its correct position in stable way. Then, the completed welding seam will grow crooked with inconsistent seam height and cover face;
2) This not only deteriorates appearance of finished welding seam, but more seriously is, inferior welding quality delivered from H Beam Welding Machine;


2. The Eminent Design and Workmanship of Welding Seam Tracing unit in Wuxi JACK H Beam Welding Machine: 

Fig1 H Beam Welding Machine_20210629110243

1) As you can check from the above photo, Wuxi JACK has ingenious design, real talent and material on welding seam tracing unit equipped in our H Beam Welding Machine. The seam tracer has spatial three dimensional tracing ability in precise manner;
2) There are leaning rollers for both horizontal and vertical direction tracing, which touch with surface of horizontal welding seam and vertical mounting carriage tightly in dynamic way;
3) During working process of the H Beam Welding Machine, the up and down movement of seam tracer works in floating style, while horizontal movement is driven with pneumatic valves. This gives flexible and most fitting control of welding seam tracer in all directions;


3. The Working Manner of Welding Seam Tracing unit in Wuxi JACK H Beam Welding Machine:

1) The working of welding seam tracing unit in H Beam Welding Machine is automatic;
2) The welding flux feeding tubes are integrated into this welding seam tracing unit, making compact design and dimension of the entire welding group in H Beam Welding Machine;
3) Please check quality of finished SAW welding seam delivered from Wuxi JACK H Beam Welding Machine with the supplementary unit of welding seam tracer:

The Characteristic, Applicable Workpiece and Application of Open Structure H Beam Welding Machine

1. The Structural Feature and Fitting Working Part of Open Structure H Beam Welding Machine: 

Fig1 LHC H Beam Welding Machine sketch      Fig2 LHT H Beam Welding Machine sketch
1) As you can observe from the above design sketch of LHC column boom and LHT T frame H Beam Welding Machine, the common point of these two types of H Beam Welding Machine is their open structure. This is where its product name got from;
2) For the same reason, any one size of H Beam and T Beam in practical use, from as small as 200mm height, to as big as 2000mm height, can be welded on the same one model of either LHC or LHT H Beam Welding Machine;
3) If there is no platform at bottom of the T frame, as shown in below photo, the LHT T frame H Beam Welding Machine can also be used for welding BOX Beam. Under such condition, the workpiece should be placed inside the T frame, instead of H Beam at the external side of T frame.

2. The Application of Open Structure H Beam Welding Machine:

1) LHC column boom H Beam Welding Machine is basically used in automatic heavy duty H Beam Production Line, welding one pass of seam on one piece of H Beam in one time operation;
2) LHT T frame H Beam Welding Machine is applied in semi automatic H Beam Production Line, welding one pass of seam on two pieces of H Beam simultaneously in one time operation. Or, as we mentioned just now, in BOX Beam Production Line.

1. Definition on LHC Column Open Structure H Beam Welding Machine:

1) LHC is the type of H Beam Welding Machine dedicatedly applied in automatic H Beam Production Line;
2) Same as LHT, there is only one model in LHC H Beam Welding Machine: All the web heights of H Beam and T Beam can be welded in such open structure type of H Beam Welding Machine.

 

 

2. The Uniqueness of LHC Column Open Structure H Beam Welding Machine:

Compared with the other two types of H Beam Welding Machine: LHA gantry and LHT T frame, the four unique features with LHC H Beam Welding Machine are:
1) There are no workpiece racks necessary for LHC H Beam Welding Machine. Instead, H Beam and T Beam are put onto the 60° Overturning Rack of the H Beam Production Line, as you check from the left hand photo;
2) There is only 1 piece of SAW welding torch in one set of LHC H Beam Welding Machine. So, every time only one pass of welding seam can be finished;
3) The on site application of LHC H Beam Welding Machine in automatic H Beam Production Line involves 4 sets of such equipment working as a group, instead of one set only as in the case of LHA and LHT. This is the reason that, as you can find from the left hand design drawing, why LHC H Beam Welding Machine is usually deployed in symmetry inside automatic H Beam Production Line;
4) Also, because of its automatic H Beam Production Line use, material handling in LHC H Beam Welding Machine is safe and labor saving: The flipping and moving away of workpiece is done with 60° Overturning Rack and Steel Conveyor.
