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;
2) This is the reason that, for firmly welding the T Beam H Beam with reliable outcome, large current submerged arc welding technique is the most proper solution, and it needs to be in the position of 45° fillet welding. Please check on below close up on working moment of H Beam Welding Machine:
1) The jumbo T Beam H Beam welded in such position at H Beam Welding Machine have the best degree of penetration and welding cover, which can meet the requirement on steel structure use;
2) Besides, the most convenient and intuitive visual angle for operator can be got, to check the SAW welding process in the H Beam Welding Machine, as you can find from the above photo;
3) Different from H Beam Fabrication Machine, which welds T Beam and H Beam with the traveling of working parts, in H Beam Welding Machine, the working way is like this: Workpiece is laid stationary on its holding rack, while welding torch moves two ways to perform welding.
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”;
4) For quick understanding on technical strong points of this equipment in H Beam Production Line, please check thematic page of “Wuxi JACK H Beam Welding Machine Slides”.
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;
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;
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:
4) If you have interest, please check product of LHC Column type SAW Automatic H Beam Welding Machine.
As a technology company, Wuxi JACK concentrates on exploring technical knowhow in our product, to get the best performance of product. For H Beam Welding Machine, one of the critical control points is welding seam tracing mechanism, which determines submerged arc welding quality of the H Beam Welding Machine directly:
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.
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.

LHT T Frame H Beam Welding Machine is the intermediate product comes into middle between LHC and LHA:
1) The main body of LHT H Beam Welding Machine has T shape structure, this is where its product name of T Frame H Beam Welding Machine coming from, which looks fairly similar to a set of LHA Gantry H Beam Welding Machine;
2) Also, same as LHA Gantry H Beam Welding Machine, in one set of LHT T Frame H Beam Welding Machine, there are 2 pieces of welding torch installed on 1 set of machine. So, 2 pieces of working parts can be welded at the same time in this machine;
3) Same as LHA, LHT H Beam Welding Machine is also for being applied in semi automatic H Beam Production Line. So, its material handling including overturning and transporting of workpiece is also toilful, which needs special attention in the process for operator safety and workpiece protection;
4) Same as LHC column structure H Beam Welding Machine, and different from LHA Gantry H Beam Welding Machine, LHT H Beam Welding Machine has open style main body of T Frame, which has no limitation on its workpiece size. So, there is only one model in LHT H Beam Welding Machine;
It has universal application, or, sometimes we call it “One machine with triple use”, that benefitting from its mechanical structure of T frame, the suitable workpieces for LHT H Beam Welding Machine is not confined to H Beam and or T Beam. Instead, BOX Beam and Cross Beam can also be welded in the LHT;
